Thermo Forma 3911 Refrigerated Environmental Incubator

  • Single 11 cubic foot chamber
  • Temperature range: 0°C to 60°C
  • Humidity range: ambient to 95% at 37°C
  • 90-day warranty

The Thermo Forma 3911 environmental incubator is ideal for drug stability studies, shelf life testing for packaged products, cell culture, and insect and other biological research applications. The Thermo Forma 3911 meets ICH guidelines for drug substance and product storage testing and has a wide temperature range from 0°C to 60°C set in 0.1°C increments for compliance with regulatory requirements. A positive pressure feed plenum on one side of the chamber and negative pressure plenum on the other side creates a horizontal laminar airflow system that distributes air throughout the chamber and increases temperature uniformity, stability, and recovery after the door is opened. Watlow EZ-Zone control panels run temperature and humidity.

All of the equipment we sell is used and reconditioned. We 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.
