The Forma 3950 reach-in incubator is a large capacity incubator provides a generous 29 cubic foot chamber for culturing large volumes of patient samples for bacterial growth, performing short-term growth studies and work with large volume products. The Forma 3950 features elevated relative humidity to prevent product desiccation in medium term cultures and three different water fill options. The heated, tripled-pane glass door minimizes condensation and provides users with a clear view of the chamber. Two through-wall access ports can be used to run sensors, probes, or power cords for small instruments into the chamber, or sealed. The Forma 3950 also features a directed horizontal laminar airflow system with positive and negative plenums so that each shelf receives a consistent flow of conditioned air for optimum temperature uniformity.

All of the equipment we sell is used and reconditioned. We test CO2 incubators using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts, as well as using a Fyrite indicator to measure CO2 levels in the chamber. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment.

The photos above are representative. 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.
