Isolation Value

The basic function of this manually operated isolation valve is to isolate the drying accessory and sample from the ice condenser and pump. This is also useful in injecting inert gas before sealing the vials and for determining the dryness of the sample by measuring the vapour pressure in the drying accessory.

The system has acrylic vacuum chamber with lid and upto five shelf rack assembly and trays. The acrylic vacuum chamber gives a clear view of the product and transmits radiant heat energy for drying. It is easily sealed by drop on acrylic lid with lead through for heater accessories. A conveniently designed rack supports up to 5 one litre stainless steel trays, and is ready wired to accept low voltage, heater pads under each tray. The design allows selection of any tray & heater combination for maximum utilization. It can be easily lifted in and out of freezer units. This system can also be used with temperature control unit for careful control of drying rate.

The heater control unit is a freestanding power supply unit designed to deliver a thermostatically controlled low voltage power supply to the heaters. The heat energy produced by the heater mat under each shelf enhances the drying rate.
