BFS-MP Series from Physitemp

Physitemp’s new line of temperature controlled freezing stages incorporates several innovative features at a lower cost than our 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.
