Physitemp's BFS-Series of temperature con­trolled freezing stages incorporates a wide range of several Instuments. The new line of temperature con­trolled freezing stages has innovative features at a lower cost than older TC series controllers. These controllers are designed around a new generation of switch­ing power supplies which are smaller and lighter than the older BFS supplies. The sup­plies are overated 100% to ensure cool opera­tion and continuous service.

Technical features include:

¤  110 and 220V operation by switch selection
¤  Temperature control to within 0.5°C in the range of -40°C to ambient
¤  Thaw switch to quickly defrost frozen samples
¤  Safety features include overtemperature alarm with power shut down in the event of inadaquate flow of cooling
     water or overuse of the thaw feature
¤  Controller incorporates fan assisted internal cooling to maintain low internal tempera­tures
¤  Continuous display of both set and run tem­peratures
¤  Simple temperature control setup
¤  Auxiliary switched AC output for acces­sories ( option
¤  P.I.D. microprocessor based temperature controller with autotuning feature and sensor breakage warning
¤  Combined carrying handle with adjustable base for convenient adjustment of display viewing angle
