The Nuaire NU-437-400 is a Class II Type A2 bio safety cabinet that can either be exhausted back into the lab space or connected to facility HVAC system. The cabinet’s airflow is 30% exhausted/70% recirculated, minimizing cross-contamination of low to moderate risk biological in the absence of volatile toxic chemicals. The NU-437-400 features Nuaire’s FlowGard Control System which monitors plenum pressure and provides both audible and visual alarms to alert users to problems with airflow.

All of our equipment is used and reconditioned. Our technicians test each bio safety cabinet to insure that the controls and blower motor work properly. Unless otherwise specified all bio safety cabinets come with new HEPA filters installed by our technicians at our facility prior to shipment. Our testing procedure includes all the elements of a bio safety cabinet certification in order to insure that the unit will pass certification once it is at your site.

Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
