Main Application

Drying samples such as protein
Drying of food sample for analysis
For other applications which requires lyophilization

Features

Available of nitrogen gas purge and output signal of recorder for vacuum

Side terminal panel of main body

When vacuum is released, it can make it filled up with N2 (nitrogen) gas etc. instead of air (nozzle Pisco φ6mm).When connecting cylinder, it becomes entry speed of about 1 L/min and below 0.1MPapressure.It also available of output signal of vacuum recorder by RS-232C.Optional connection cable is available.

User-friendly operation

It starts cooling chamber in 5 minutes after powered on.Blue LED is lit and tells you when reach to trapping temperature.Dryness can be judged by light position of LED when reached vacuum degree set in advance with our new digital Pirani vacuum gauge.

LED display setting of vacuum is possible

You can check current status and standard maintenance time of oil rotary vacuum pump in addition to number display of vacuum degree Pa by three LED displays of air pressure,vacuum dried area and freeze dried area.Even when you change pumps, changing LED light setting to meet capacity of the pump by no- load operation makes it easy to check causes of vacuum problem.

Designed to minimize influence by sample contamination.

A trap chamber or pipes are all made of stainless and connected each other with vacuum hoses free from dusts. It makes easier operation for analytical purpose since it uses 0.22 μm filters at leakage path.

Perfect cold tarpping of sublimated moisture.

Direct cooling system which vapor is coagulated and collected on the coil surface in chamber directly which means cooling temperature almost equals to the trapping temperature.

Quick thawing of trapped moisture by hot gas

You can thaw ice in short time by pressing “defrost button” with hot gas flowing around the coil. It can thaw ice the portion of dehumidified amount for about 30 minutes.
