For some sectioning work it is necessary to cool a specimen below room temperature. The Bright Solid State Freezer incorporates a Peltier device cooling stage and will permit specimen cooling from ambient to -25°C or lower, depending on conditions.
The equipment consists of a control unit and a cooling stage, with the cooling stage available in two sizes – 30mm x 30mm or 40mm x 40mm. Primarily designed for use with the Bright 5040 rotary and the Bright 8000 base sledge microtomes, the Solid State Freezer may be used with other rotary and sledge microtomes.
The Solid State Freezer fits to the microtome in place of the normal specimen holder. It has a water inlet, a water outlet and an electrical connection to the control unit. The control unit permits temperature control but does not measure temperature directly, instead a reading of the current passed to the Peltier device is indicated on the front panel. The control unit also has a built in safety device, which detects low water flow. After sectioning, the specimen is quick and easy to remove.
