Temperature Controller

The Temperature Controller is a freestanding power supply that delivers a controlled low voltage output to up to six optional heater mats used in the drying tray kit. Adding heat energy enhances the drying rate of material in the product trays. The controller regulates heat input by monitoring the temperature of the mat. Mat temperatures may be adjusted from 0 °C to 45 °C, to a point that will add heat energy to, but not melt the samples.

Isolation Valve

The Isolation Valve is a high quality, multipurpose device that is used in conjunction with a variety of freeze drying accessories. The basic function of the manually operated valve is to isolate the drying accessory, and sample, from the ice condenser and pump. With the Isolation Valve closed, the condenser chamber can be evacuated while samples are loaded on the drying accessory. When opened, system vacuum levels fall more quickly. Isolating the drying accessory in this manner will allow the user to apply an external vacuum gauge and measure the vapor pressure in the drying accessory. This information is useful in determining the dryness of the sample. The same accessory port (pressure rise test) may also be used to back-fill the sample containers with an inert gas such as dry nitrogen prior to sealing.

The Isolation Valve will not work with the cold trap adapter (SAV-F05660000), pipeline attachment (SAV-F02305082) or Spin Freezer 96. The Isolation Valve may be used with the MicroModulyoD or SuperModulyo base units.
