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, insect and other large-scale biological research.\u003c\/p\u003e\n\u003ch2 class=\"MsoNormal\"\u003eThermo Forma 3940 features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCapacity: 29 Cu.

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% increments.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe humidity system requires a water purity in the resistance 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 pressurized (up to 40PSI) or unpressurized.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eIf 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.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThis 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.\u003c\/p\u003e\n\u003ch3 class=\"MsoNormal\"\u003eThermo Forma 3940 - additional features\u003c\/h3\u003e\n\u003cp class=\"MsoNormal\"\u003eTemperature 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. \u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe 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.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003ca title=\"Link to YouTube\" href=\"https:\/\/youtu.be\/8KqqdMnrR1U\"\u003e\u003cem\u003e\u003cstrong\u003eCLICK HERE \u003c\/strong\u003e\u003c\/em\u003e\u003c\/a\u003e\u003cstrong\u003eto see the unused Thermo Forma 3940 refrigerated environmental chamber on our YouTube channel\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/8KqqdMnrR1U?si=h8ohXtVgEYLnUDb7\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch3 class=\"MsoNormal\"\u003eThermo Forma 3940 Refrigerated Environmental Chamber Testing\u003c\/h3\u003e\n\u003cp class=\"MsoNormal\"\u003eMost of our equipment is used and reconditioned.
