Source Capture Is the Cheapest Air-Quality Win in a Fertility Clinic

Embryology laboratory suite with benchtop incubators, a laminar flow workstation and HEPA-filtered clean air
Culture suites depend on clean, stable, positive-pressure air — source capture keeps contaminant out of that air path

An assisted reproductive technology laboratory is one of the very few environments where the product being handled has no protection of its own. Gametes and embryos sit in open dishes under oil, in an incubator that breathes the room, for days at a time. Airborne volatile organic compounds do not need to be at an occupational-exposure concentration to matter here — the published thresholds discussed for IVF suites are in micrograms per cubic meter, orders of magnitude below anything an industrial hygienist would flag.

Most of that contaminant load is generated inside the clinic, not outside it: alcohol used to wipe benches and equipment, fixatives and stains on the andrology bench, solvents from adhesives and flooring, aerosol cleaners, and off-gassing casework. A lab snorkel — an articulated extraction arm you position an inch or two above the release — removes that contaminant at the point it is created, using a fraction of the air a fume hood or a room-air change would need.

That is the honest role of a snorkel in an IVF clinic. It is not a substitute for HEPA and carbon filtration, positive pressure or a properly designed pressure cascade. It is the layer that stops solvent vapor from ever entering the air path those systems have to clean.

Where the VOCs in an ART Laboratory Actually Come From

Air-quality work in a fertility clinic goes wrong when it is treated as a filter purchase. The published reviews of embryology-laboratory air quality consistently trace measurable VOC load back to building materials, furniture, cleaning practice and adjacent processes. Each of those needs a different control — and only some of them are solved at the bench.

Contaminant Typical source in a clinic Control that actually works
Alcohols (isopropanol, ethanol) Bench and equipment disinfection, sample handling Capture at the bench with an extraction arm; switch to lower-emission wipe protocols
Formaldehyde Wood-based casework and furniture, adhesives, fixatives Specify low-emission casework; capture fixative work under a CHEM arm or hood
Solvents from flooring and adhesives PVC flooring, carpet, vinyl floor adhesive, paints Low-VOC materials plus a documented off-gassing period before the lab is commissioned
Cleaning-product volatiles Waxes, ammonia-based and aerosol cleaners Approved cleaning list for the clean suite; do the aggressive cleaning under capture
Refrigerant and combustion products HVAC equipment, loading docks, generator exhaust Fresh-air intake siting and pressurization — an HVAC design issue, not a bench issue
Particulates and microbial contamination Personnel, corridors, positive-pressure failures HEPA filtration and a positive-pressure cascade into the culture room

What the guidance says

The ESHRE revised guidelines for good practice in IVF laboratories call for laboratory air to be subjected to high-efficiency particulate (HEPA) and VOC control, with positive pressure recommended to minimize air contamination. The Cairo consensus on the IVF laboratory environment and air quality treats facility design, the HVAC system, particulates, microbial contamination and VOCs as one linked problem, and published clinical work has reported improved outcomes after laboratory air quality was improved. Use those documents with your embryology director — no equipment purchase, including ours, delivers compliance on its own.

Where Lab Snorkels Belong in an IVF Clinic

The rule is simple: put the arm where the contaminant is created, and keep it out of the culture room. These are the placements we specify most often in fertility and reproductive medicine laboratories.

Articulated extraction arm positioned over an andrology bench during semen analysis sample preparationAndrology & Semen ProcessingSperm wash and preparation stations use fixatives, stains and alcohol. A 2″ or 3″ arm over the bench pulls those vapors away before they can migrate toward the embryology suite next door — the single most common lab snorkel placement in an ART clinic.
Extraction arm capturing alcohol vapor above a media preparation bench in an IVF laboratoryMedia Preparation & Bench DisinfectionIsopropyl alcohol from routine wipe-down is one of the most persistent airborne contaminants measured in IVF laboratories. A dome hood over the prep bench captures the vapor at release instead of letting the room air handler dilute it.
Extraction arm capturing solvent fumes over a histology staining bench beside an embryology laboratoryStaining, Fixing & HistologyOpen staining dishes and fixatives are a point source of formaldehyde and solvent vapor. A CHEM arm with a metal hood is the right specification here; an ORIGINAL arm will corrode.
Ceiling-mounted extraction arm above cryogenic storage dewars in a fertility clinic cryostorage roomCryostorage & Transfer StationsExtraction arms are used over cryo transfer and thaw workstations to carry off vapor and solvent fumes. Important: an extraction arm is not oxygen-deficiency protection — liquid nitrogen rooms still need dedicated room ventilation and an O₂ monitor.
Row of articulated extraction arms installed over benches in a working laboratoryAdjacent Analytical & QC BenchesClinics that run their own hormone assays, water testing or QC chemistry install arms along the analytical bench line so one duct run serves several stations.
Laboratory technician in a mask working beneath a wall-mounted fume extraction armInstrument & Maintenance AreasAdhesives, sealants and cleaning solvents used during instrument service produce short, intense releases. A single arm over the service bench keeps those out of the shared air path.

One placement to avoid

Do not install an extraction arm over an open embryo culture or micromanipulation station. Those areas are designed for stable, HEPA- and VOC-filtered, positive-pressure air with minimal turbulence; a local exhaust point works against that design and can draw room air across the work. Capture upstream instead.

Three Arm Models — ORIGINAL, ESD/EX and CHEM

All three share the same geometry, the same mounting brackets and the same optional hoods. What changes is the material set, and that is driven by the chemistry on the bench.

Nederman BenchTop ORIGINAL exhaust snorkel arm with anodized aluminum tubes and blue friction adjustment knobsORIGINAL ModelThe all-round arm for general laboratory work where there is little risk of electrostatic discharge or attack by aggressive chemicals. Anodized aluminum tubes, polypropylene joints and a transparent combi hood. This is the model most fertility clinics use over andrology and media-prep benches.
Nederman BenchTop ESD/EX exhaust snorkel arm built from conductive materials for static-sensitive workESD/EX ModelBuilt from conductive materials — conductive polypropylene joints, conductive EPDM duct connector and a conductive mini hood — so static electricity and sparks cannot build up. Specified for static-sensitive instrumentation areas and, after a formal risk assessment, for certain flammable-vapor applications. Carries ESD, CE and EX certifications.
Nederman BenchTop CHEM exhaust snorkel arm with double-anodized profiles and a corrosion-resistant metal hoodCHEM ModelProfiles are double-anodized aluminum and the hood is a painted, corrosion-resistant metal hood. This is the arm for aggressive chemistry: fixatives, acids, strong solvents and staining lines where an ORIGINAL arm would not last.

Lab Snorkel Specifications

Capacity by arm diameter

Pick the diameter from the release you are capturing, not from the duct you happen to have. Undersizing shows up as fume escaping around the edge of the hood.

Arm Diameter Airflow range Typical laboratory use
FX32 1-1/4″ (32 mm) One-piece self-supporting flexible arm for very low-volume capture
FX50 2″ (50 mm) 30–65 CFM (50–110 m³/h) Single-point capture at a microscope or prep station
FX75 3″ (75 mm) 65–140 CFM (110–240 m³/h) The standard laboratory size — open dishes, staining, general bench work
FX100 4″ (100 mm) 120–265 CFM (200–450 m³/h) Larger releases, higher heat, or a hood shared by two adjacent stations

3″ arm dimensions and reach

The 3″ (FX75) arm is the laboratory standard. Two arm lengths are stocked; both take the same hoods and the same bracket.

Materials and limits

Component Material Why it matters
Tubes Anodized aluminum (double-anodized on the CHEM model) Light enough to reposition one-handed; the CHEM finish resists corrosive vapor
Joints Polypropylene (conductive PP on ESD/EX) Ball-bearing-supported friction joints hold position without drifting
Duct connector EPDM rubber (conductive EPDM on ESD/EX) Flexible, chemical-resistant transition to your duct
Mini hood Polypropylene (conductive PP on ESD/EX; metal on CHEM) Universal interface for all optional hoods
Max fume temperature 158°F (70°C) Above that temperature you need a metal hood and a different arm family
Installation Indoor, wall / ceiling / floor / bench mount One bracket family covers every mounting position

Reach one arm, serve two benches

An extension profile increases the arm’s reach so a single arm can serve two adjoining workstations. In a small clinic that is often the difference between one duct penetration and three. Send us the bench layout and we will show you where the shared positions work.

Hoods: The Part That Decides Capture Efficiency

Every BenchTop arm arrives with a 5.5″ universal mini hood, and any of the optional hoods below attaches directly to it regardless of arm diameter. Choosing the right hood shape matters more than adding airflow.

Transparent PET-G combi hood attached to a lab snorkel mini hood, usable as a dome or a screen hoodCombi HoodTransparent PET-G hood that works as both a dome and a screen hood, angled to suit the task. Fully transparent with no optical distortion, so a technician can watch the work while it is being captured. Part 70500144 (ORIGINAL) / 70500344 (CHEM).
Transparent dome hood on a lab snorkel arm for capturing high-dispersion fumesDome HoodThe transparent dome hood suits high-dispersion contaminants — vapor coming off an open dish or tube rack rather than a single point. Clips straight onto the universal mini hood. Part 70376982 (ORIGINAL) / 70376984 (CHEM).
Powder-coated aluminum metal hood on a lab snorkel arm for aggressive fumes and higher temperaturesMetal HoodPowder-coated aluminum for aggressive fumes, higher temperatures and dust, with excellent corrosion resistance. Standard on the CHEM arm. Part 70500444.
Close-up of the universal mini hood supplied as standard on every BenchTop extraction armUniversal Mini Hood (standard)Every BenchTop arm ships with a 5.5″ mini hood, so no extra extraction nozzle is required. It is also the universal interface — combi, dome and metal hoods all attach directly to it, regardless of arm diameter.
Transparent screen hood of a lab snorkel drawing dust and powder off a work surfaceScreen Position for PowdersAngled as a screen, the combi hood pulls dry powder and particulate away from the operator instead of over the bench. Useful anywhere a clinic weighs out media components or reagents.

Mounting, Ductwork and Installation

Wall-mounted arm positioned over a bench — the most common installation in a finished clinic

The multi-purpose bracket lets the same arm be mounted to a ceiling, a wall, the floor or directly to a bench top, with the duct connection running up or down to suit. That flexibility is what makes arms practical in a finished clinic where the ceiling grid and the casework are already in place.

Drop ceilings

Run the arm up through the grid using the 43″ (1,100 mm) trimmable extension tube, cut to the height you need, and finish the penetration with the optional ceiling cover plate. No custom fabrication is required.

Fans, filters and ducting

An arm is a capture device, not a complete exhaust system. It has to be connected to a fan and discharge — either a self-assembly kit with its own fan, filter, speed controller and hoses for a single station, or a tie-in to the building exhaust. That work belongs to a mechanical contractor, and in a fertility clinic the tie-in has to be reviewed against the room pressure cascade before anything is cut in. We coordinate that review; we do not guess at it.

1

Walk the workflow

We map every place a volatile is opened, poured, wiped or fixed, and how air currently moves between those rooms and the culture suite.

2

Size and site each arm

Diameter and hood come from the release; position comes from reach, sight lines and the bench the technician actually uses.

3

Coordinate the mechanical scope

Fan, duct route, discharge and the effect on room pressurization — agreed with your engineer or contractor before release.

4

Install and commission

Arms, brackets, extensions and hoods installed, dampers balanced, and capture verified at each station with the technicians who will use it.

When You Need a Bench Top Fume Hood Instead

An extraction arm is the right answer for a small, identifiable point source. Once the work itself needs to be enclosed — larger solvent volumes, splash risk, continuous use, or a protocol that calls for a certified containment device — you want a bench top fume hood on the same bench instead.

The ICI-JMP Isolator³ is the bench top hood we specify most often for research and healthcare laboratories. It achieves capture and containment at a 60 FPM face velocity with a 24″ (61 cm) sash opening by controlling baffle pressurization, rather than by adding air into the hood chamber. It is UL/CSA 1805 listed, tested in accordance with ASHRAE 110, SEFA 1 certified, and meets or exceeds SEFA 8 chemical resistance. The liner is chemically resistant Polyglass and the sash is tempered glass with a full-length formed steel handle. Lower face velocity means less conditioned air exhausted from the building, which matters in a clinic already paying for HEPA and carbon filtration.

Explore the full range on our laboratory fume hoods page, or compare it against the ESD-safe arm range on our Movex ESD snorkels page.

  • Point source you can put a hood over, seen by the operator → extraction arm
  • Work that must be enclosed, or a certified containment device required → bench top fume hood
  • Corrosive fixatives, acids or aggressive solvents → CHEM arm or a hood, never an ORIGINAL arm
  • Static-sensitive or flammable-vapor area → ESD/EX arm after a documented risk assessment
  • Liquid nitrogen storage → room ventilation plus an oxygen monitor, not an extraction arm
  • Open embryo culture and micromanipulation → filtered positive-pressure supply air, no local exhaust

What We Need to Quote Your Lab

Specify capture around the technician’s real working position, not the drawing

Quoting extraction arms is quick once we know the work. Send us the following and we will come back with arm models, hoods, mounting kits and, if you want it, the installed price:

A floor plan or sketch with the benches marked; what is opened or wiped at each station and roughly how often; the bench and ceiling heights; whether there is an existing exhaust duct or fan nearby; whether the room is part of a pressurized clean suite; and whether the finish has to match existing casework.

We supply laboratory ventilation alongside the casework, shelving, storage and layout work we do for hospital, university and clinical laboratories across the Mountain West, so an arm can be quoted as part of a bench package rather than as an orphan line item.

Lab Snorkel FAQs

What is a lab snorkel?
A lab snorkel — also called an exhaust snorkel, extraction arm or fume extraction arm — is an articulated duct on a wall, ceiling, floor or bench bracket that you position directly over a source of fumes, vapor, dust or heat. The two outermost joints rotate and swivel through 360°, and friction devices in the joints lock the hood where you set it. Because it captures at the source rather than diluting the whole room, it removes contaminant with a fraction of the airflow a fume hood needs.
Should a lab snorkel be installed inside an embryology culture room?
Almost never directly over open culture work. Embryology culture areas are designed to run at positive pressure with HEPA and VOC-filtered supply air and very stable, low-turbulence airflow; putting an exhaust arm over an open dish works against that design and can pull room air across the work. The correct placement is in the rooms that generate the contaminant — andrology, media prep, staining, cryo transfer, QC chemistry and instrument service — so that vapor is removed before it can migrate into the culture suite. We size and site them with your embryology director and your mechanical engineer.
What sizes and airflows are available?
Nederman BenchTop arms come in 2″, 3″ and 4″ diameters with capacity ranges of 30–65 CFM (FX50), 65–140 CFM (FX75) and 120–265 CFM (FX100), plus a compact 1-1/4″ FX32 one-piece arm for very small volumes. In laboratories the 3″ arm is the usual choice; its maximum working radius is 42.9″ (109 cm) or 57.1″ (145 cm) depending on which arm length you order.
Which model do we need — ORIGINAL, ESD/EX or CHEM?
ORIGINAL for general fumes, dust and heat. ESD/EX where static discharge is a risk, or — only after a documented risk assessment — in certain flammable-vapor areas; it uses conductive joints, connector and hood. CHEM where corrosion resistance matters: double-anodized profiles and a painted metal hood for fixatives, acids and aggressive solvents. All three take the same optional hoods.
Do lab snorkels include a fan and ductwork?
The arm ships with its mounting bracket, a 43″ (1,100 mm) trimmable extension, a damper and the universal mini hood. It still has to be connected to an exhaust system. Nederman also offers self-assembly kits that include a fan, filter, speed controller, hoses and connectors for a single station. Tying an arm into a building exhaust or a new dedicated fan is mechanical-contractor work, and in a fertility clinic it must be reviewed against the pressure cascade of the clean suite before anything is cut in.
Can an arm be installed into a drop ceiling?
Yes. Use the trimmable 43″ extension tube, cut to the height you need, with the optional ceiling cover plate for a finished appearance. The bracket family also supports wall, floor and bench-top mounting, with the duct connection running either up or down depending on the position.
When should we use a bench top fume hood instead?
Use an arm when the release is a small, identifiable point source you can put a hood over. Use a bench top fume hood when the work itself has to be enclosed — larger volumes, splash risk, continuous solvent use, or a protocol that requires a certified containment device. Bench top hoods such as the ICI-JMP Isolator³ achieve capture and containment at a 60 FPM face velocity with a 24″ (61 cm) sash opening, are UL/CSA 1805 listed and tested to ASHRAE 110, and are SEFA 1 certified.
Do extraction arms replace VOC filtration in an IVF lab?
No. Published guidance for IVF laboratories asks for HEPA and VOC control on the air serving the lab, together with positive pressure, and the Cairo consensus on the IVF laboratory environment treats air quality as a whole-facility problem. Source capture is the first and cheapest layer: it stops contaminant from entering the shared air in the first place, which reduces the load on the carbon and permanganate media downstream. The two work together.
