Vacuum pump is option

Compact size to fit inside draft

Main Application

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

Features

Small trap for centrifugal condenser become tlyophilizer

This product is a set of specialized lyophilizing option to freeze trap VA-140S for centrifugal condenser on P.157. It is optimum for small amount of sample and can be used as small lyohilizer which can be set inside draft.

Stirling cooler save energy and non Freon

Operation current of cooler is only 1A and can save electricity during long operation time of lyophiliation.

Sublimated moisture can be trapped inside glass bottle at below -50ºC

Moisture is trapped in attached glass bottle and that makes discard easy and can be used for solvent such as acid which is difficult to use before. Sine cooling of glass bottle is indirect cooling with antifreeze, it can be used just like as low temperature trap of centrifugal condenser.

Can combine to centrifugal condenser

When connect vacuum hose to nitrogen gas purge nozzle of multi branched tube unit, it can be used as low temperature trap for centrifugal condenser VC-15S/ 15SP with keeping lyophilizer condition.
