●For other applications which requires lyophilization
Features
Available of nitrogen gas purge and output signal of recorder for vacuum
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.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.Specifications
