General Catalog

Features

Simple operation

Turn on the power. When the blue button lights up, the unit is ready for use. Pressing the yellow VAC START button will turn on the pump that is connected to the vacuum pump interlocking outlet on the back of the unit, and then vacuuming starts.

Secure cold trap for the sublimated water

Because of the direct cooling system in which water vapor is directly coagulated and collected on the surface of the cooling coil in the trap chamber, the cooling temperature becomes almost the same as the trap temperature.
Trapped water is quickly defrosted by hot gas. When the DEFROST button is pressed, hot gas will flow into the coil of the cold trap, and ice equivalent to the dehumidification capacity can be defrosted in about 30 minutes.

Setting and display function of Ultimate vacuum range

Displays Atmospheric pressure range/ Vacuum drying range/Lyophilization range in order with the LED when decompression starts to notify the progress of decompression. The setting can be changed according to the application. It can also be used for pump maintenance.

Signal output, leak port

The VD-550R and 800R can record the vacuum degree. For samples that are resistant to oxidation, a nitrogen gas purge can be performed from the leak port on the back of the main body (equipped on the 250R/550R/800R) when the vacuum is released to minimize the effects of oxidation.
