Forma Reach-in refrigerated incubator chambers are perfect for applications that require temperature control below and/or above ambient, e.g. storage, testing, and incubation at low temperatures. The refrigerated incubator chambers meet International Conference on Harmonization (ICH) guidelines for drug substance and product storage testing. The units are ideal for drug stability studies, shelf life testing for packaged products, and insect and other large-scale biological research.

These chambers feature a 0°C to 60°C (32°F to 140°F) temperature range that can be set in 0.1°C increments. The broad temperature range, and optimum temperature uniformity and recovery contribute to an ideal test environment, even when the chamber contains large product loads and low-output, heat-generating equipment. They also feature a humidity control system, which allow you to set the RH level between ambient and 95% in 1% incriments. The humidity system requires a water purity in the risistance range of 50K to 1M Ohm/cm, or a conductivity range of 20.0 to 1.0 uS/cm. The water source can be either presurized (up to 40PSI) or unpresurized. If an in-house water supply of the required purity range is not available, an alternate method can be used. A large vended carboy (5 gal. minimum) of water in the required purity range can be placed on top of the unit.
This combination directs air across the surface of each solid shelf. Even when filled with samples or equipment, each shelf receives a consistent flow of conditioned air for optimum temperature uniformity and recovery. As opposed to a horizontal airflow system, top-to-bottom (non-directed) airflow systems use a top-mounted fan to push air down through wire shelves. Temperature uniformity and recovery can deteriorate quickly when shelves are filled because air movement is blocked. That variation in temperature, alone or when combined with frequent door openings, may compromise environmental conditions, or make process validation difficult.
The Thermo Scientific Directed Airflow System promotes an ideal growth environment. The enhanced design includes a positive pressure feed plenum on the right side of the chamber and a negative pressure return plenum on the left to distribute the airflow uniformly throughout the chamber.
All of our equipment is used and reconditioned. Our technicians test incubators using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts. 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.
