<h2>How to Choose a Biosafety Cabinet</h2>
<p>Selecting a biosafety cabinet requires matching the cabinet's design to your specific workflow, facility infrastructure, and containment requirements. Key considerations include:</p>
<ul>
<li><strong>Cabinet class and type:</strong> Class II cabinets are the most common for biological research. Type A2 recirculates a portion of air through HEPA and exhausts the remainder — suitable for most BSL-1 and BSL-2 work not involving volatile chemicals. Type B2 exhausts 100% of air through hard ducting — required when working with volatile toxic chemicals alongside biological agents.</li>
<li><strong>Cabinet width:</strong> 3-foot, 4-foot, and 6-foot work surface widths are standard. Match cabinet width to your workflow volume and available bench space.</li>
<li><strong>Exhaust requirements:</strong> Type A2 cabinets can be used unducted or with a canopy connection. Type B2 cabinets require a dedicated hard-ducted exhaust system — confirm facility HVAC compatibility before ordering.</li>
<li><strong>Electrical requirements:</strong> Confirm voltage, amperage, and outlet configuration match your facility.</li>
<li><strong>Ergonomics and sash design:</strong> Sash height, work opening, and interior depth affect operator comfort during extended use.</li>
<li><strong>Serviceability:</strong> Consider filter access, blower serviceability, and local service availability for the manufacturer.</li>
<li><strong>Certification requirements:</strong> Field certification is required after installation and after any relocation. Confirm certification expectations with your biosafety officer before purchasing.</li>
</ul>

<h2>Biosafety Cabinet Classes and Types</h2>
<h3>Class I</h3>
<p>Class I cabinets provide personnel and environmental protection through inward airflow but do not protect the product or sample from contamination. Rarely used in modern laboratory settings.</p>
<h3>Class II Type A2</h3>
<p>The most widely used configuration in academic and research laboratories. Type A2 cabinets recirculate approximately 70% of cabinet air through a HEPA filter back into the work zone and exhaust the remainder through a second HEPA filter. Suitable for BSL-1 and BSL-2 biological agents not involving volatile toxic chemicals. Can be used unducted or with a canopy exhaust connection.</p>
<h3>Class II Type B2</h3>
<p>Type B2 cabinets exhaust 100% of cabinet air through HEPA filtration to a dedicated hard-ducted exhaust system. Required when working with volatile toxic chemicals in combination with biological agents. Requires facility exhaust infrastructure — confirm compatibility before sourcing.</p>
<h3>Class III</h3>
<p>Fully enclosed, gas-tight cabinets providing the highest level of containment for BSL-3 and BSL-4 work. Operators work through attached gloves. Not represented in the current mLab Supply catalog.</p>
<p>The products listed on this page are Class II configurations. Contact us to confirm the specific class and type of any unit before purchasing.</p>

<h2>Biosafety Cabinets vs Laminar Flow Hoods</h2>
<p>Biosafety cabinets and <a href="/collections/laminar-flow-hoods">laminar flow hoods</a> are not interchangeable. Class II biosafety cabinets are designed to protect personnel, product, and the environment during work with biological agents through HEPA-filtered inward and downward airflow. Laminar flow hoods (clean benches) direct HEPA-filtered air across the work surface toward the operator — they protect the sample from contamination but do not provide personnel protection from biological hazards. Laminar flow hoods are appropriate for non-hazardous sterile work only. If your workflow involves biological agents, infectious materials, or requires personnel protection, a biosafety cabinet is required. Consult your institutional biosafety officer if you are uncertain which equipment is appropriate for your application.</p>

<h2>Buying Used and Refurbished Biosafety Cabinets</h2>
<p>Used and refurbished biosafety cabinets can offer significant cost savings compared to new units. When evaluating a used cabinet, key inspection points include:</p>
<ul>
<li><strong>Blower condition:</strong> Motor and blower performance affect airflow and containment. Request airflow data where available.</li>
<li><strong>HEPA filter history:</strong> Filter age, condition, and replacement history vary by unit. Do not assume filters have been replaced — confirm per unit.</li>
<li><strong>Sash and glass condition:</strong> Inspect for cracks, chips, or seal degradation.</li>
<li><strong>Airflow controls and alarms:</strong> Confirm controls and alarm systems are functional.</li>
<li><strong>Work surface and interior:</strong> Inspect for corrosion, damage, or contamination.</li>
<li><strong>UV lamp:</strong> Where present, confirm lamp age and output — UV lamps have limited service life.</li>
<li><strong>Exhaust connections:</strong> Confirm exhaust configuration matches your facility requirements.</li>
<li><strong>Service history and documentation:</strong> Request available service records and prior certification documentation.</li>
</ul>
<p>Certification status, filter condition, and qualification requirements must be confirmed per unit and per buyer application. mLab Supply does not guarantee that any used or refurbished unit meets specific regulatory or institutional requirements without independent verification.</p>
</section>
<section class="mlab-collection-certification">
<h2>Certification and Installation Considerations</h2>
<p>Biosafety cabinets require field certification after installation and after any relocation. Certification is performed by a qualified certifier in accordance with NSF/ANSI 49 or applicable institutional standards. Key installation considerations include:</p>
<ul>
<li><strong>Room airflow:</strong> Cabinet placement relative to HVAC supply and return vents affects performance. Avoid high-traffic areas and locations with cross-drafts.</li>
<li><strong>Clearance:</strong> Maintain required clearances above, behind, and beside the cabinet per manufacturer specifications.</li>
<li><strong>Exhaust ducting:</strong> Type B2 cabinets require dedicated hard-ducted exhaust — coordinate with facilities before delivery.</li>
<li><strong>Transport and rigging:</strong> Large biosafety cabinets require specialized rigging for safe transport and placement. Confirm logistics requirements before ordering.</li>
<li><strong>Recertification after relocation:</strong> Any cabinet that has been moved must be recertified before use.</li>
</ul>
<p>Confirm all site requirements with your biosafety officer and facilities team before finalizing a purchase.</p>

</section>
<section class="mlab-collection-exhaust">
<h2>Facility and Exhaust Planning</h2>
<p>Type A2 biosafety cabinets can operate in recirculating mode without a dedicated exhaust connection, or with a canopy (thimble) connection to building exhaust for added chemical protection. Type B2 cabinets require a dedicated hard-ducted exhaust system sized to the cabinet's exhaust volume — this must be confirmed with your facilities team before ordering. Consider room pressure relationships, HVAC load, and exhaust fan capacity when planning installation. Model-specific exhaust requirements vary — always confirm with the manufacturer's installation documentation for the specific unit being installed.</p>
