Labconco Purifier 3980301 Class I Safety Enclosure

The Labconco Purifier 3980301 Class I Safety Enclosure is a compact personnel-protection enclosure designed for laboratory procedures involving biological agents, aerosols, powders, and other materials where operator containment is required but product protection is not. Available used and refurbished from American Instrument Exchange, this 3-foot enclosure provides an economical alternative to a Class II biosafety cabinet for applications that do not require HEPA-filtered supply air or protection of the material being handled.

Unlike a conventional chemical fume hood, the Purifier 3980301 uses controlled inward airflow and HEPA-filtered exhaust to help contain airborne particulates and aerosols generated inside the work area. The enclosure is designed for a nominal inflow velocity of 75 to 105 fpm and incorporates multiple airflow-management features to promote effective containment while maintaining a compact benchtop footprint.

Measuring approximately 35.75" W × 28.64" D × 37.05" H, the Purifier 3980301 is particularly useful for laboratories that need localized personnel protection without dedicating the space required for a full-size biosafety cabinet.

Class I Personnel Protection

The most important distinction when selecting the Labconco Purifier 3980301 is understanding what a Class I enclosure is designed to protect. Air is drawn inward through the front opening, helping prevent aerosols and airborne contaminants generated within the enclosure from escaping toward the operator.

Contaminated air is then drawn through the enclosure's exhaust filtration system before discharge. This airflow arrangement provides personnel and environmental protection for appropriate applications but does not provide product protection because unfiltered room air enters directly through the front opening.

For laboratories that need to protect personnel from an aerosol-generating process but do not need to maintain a sterile work area around the sample, a Class I enclosure can provide a practical alternative to a more complex Class II biosafety cabinet.

Common Applications

The Purifier 3980301 can be used for laboratory procedures capable of generating aerosols, particulates, or other airborne contaminants when Class I containment is appropriate. Applications may include microbiological procedures, sample preparation, tissue processing, small-scale biological research, powder handling, equipment manipulation, and other procedures where personnel protection is more important than protecting the sample from room air.

Its relatively small footprint also makes the enclosure useful for laboratories that need to isolate a specific procedure without installing a larger biosafety cabinet.

Application suitability should always be determined through an appropriate laboratory risk assessment based on the materials and procedures being performed.

Compact Benchtop Containment

At approximately 35.75 inches wide, the Labconco 3980301 provides localized containment without consuming the floor space required by a conventional freestanding biosafety cabinet or full-size laboratory hood. This makes it especially useful in crowded research laboratories, specialty testing areas, and facilities adding containment to an existing laboratory layout.

The enclosure measures approximately 28.64 inches deep and 37.05 inches high, allowing it to be positioned on an appropriate laboratory work surface or supporting base.

Its compact dimensions can also make the 3980301 attractive when a laboratory needs several dedicated containment stations for different procedures rather than one large centralized enclosure.

Airflow and Containment Design

Labconco designed the Purifier enclosure around controlled inward airflow. An ergonomic front air foil incorporates Clean-Sweep airflow openings, while side-entry air foils, an upper dilution air supply, an upper containment sash foil, and a zone-perforated rear baffle help direct air through the work area.

The enclosure is designed to operate at a nominal inflow velocity between 75 and 105 fpm. A built-in variable-speed blower allows airflow to be adjusted as required for the enclosure and installed filtration configuration.

These airflow features are particularly important during procedures that may generate aerosols or particulates, where maintaining effective inward airflow at the front opening helps reduce operator exposure.

Hinged Sash and Work Area Access

The Purifier 3980301 incorporates a tempered safety-glass front sash with a nominal 9.44-inch working opening. The angled sash provides visibility into the enclosure while maintaining the controlled opening required for normal operation.

For loading equipment or accessing the interior for cleaning, the sash can be hinged upward to provide a substantially larger opening. This makes it easier to position instruments, containers, and other laboratory equipment within the work area without compromising the smaller opening used during normal operation.

Ideal Laboratory Environments

The Labconco Purifier 3980301 is well suited for microbiology laboratories, biotechnology research facilities, pharmaceutical laboratories, university research laboratories, hospital and clinical research facilities, environmental laboratories, industrial laboratories, and other facilities that require compact personnel containment.

It can be particularly valuable where the process requires protection of the operator and surrounding environment but does not require protection of the sample from ambient laboratory air.

Refurbishment and Testing

This Labconco Purifier 3980301 is inspected and refurbished by American Instrument Exchange prior to shipment. Technicians inspect the enclosure, sash, blower system, lighting, airflow components, and other operating features as applicable to the individual unit.

Because proper containment depends on airflow performance and the condition and installation of the exhaust filtration system, laboratories should verify the required filtration and certification procedures for their application before placing the enclosure into service.

Please confirm the filter configuration included with the specific unit before purchase.

Choosing a Class I Enclosure vs. a Class II Biosafety Cabinet

A Class I safety enclosure and a Class II biosafety cabinet serve different purposes. The Labconco Purifier 3980301 is designed primarily to protect personnel and the surrounding environment. Because room air enters the enclosure through the front opening, the sample itself is not protected from contaminants present in the laboratory.

A Class II biosafety cabinet adds HEPA-filtered supply air to provide product protection in addition to personnel and environmental protection. Laboratories performing sterile cell culture, aseptic manipulations, or other procedures where sample protection is essential should generally consider an appropriate Class II biosafety cabinet instead.

For procedures where personnel containment is required but product sterility is not, the Class I design can provide a simpler and more compact solution.

Why Buy a Refurbished Laboratory Safety Enclosure from American Instrument Exchange?

Purchasing a refurbished Class I enclosure can allow laboratories to add dedicated containment capacity without the cost of purchasing a new biosafety cabinet when the application does not require Class II protection.

American Instrument Exchange refurbishes and tests used laboratory equipment before shipment and can help customers compare Class I enclosures, biosafety cabinets, chemical fume hoods, and other containment equipment based on the intended application.

The Labconco Purifier 3980301 is backed by a 90-day warranty from American Instrument Exchange.
