Active Drying Rack, 4L Dewar

The Dewar Rack provides a compact, convenient way to organize and reliably dry your 4L LN2 dewars. The active version automatically starts a drying cycle upon placing a dewar upon it and dries it out completely in 35 minutes.

A 4L dewar is placed upside-down onto the active Dewar Rack, with the drying tube inserted into the dewar. The dewar is automatically sensed and a drying cycle commenced. Ambient air is pulled through a filter and heated before being blown into the dewar; a short cooling phase brings the dewar to room temperature. An LED indicates cycle status. Compatible with both MVE and IC Biomedical 4L dewars.

Pair it with the Passive Drying Rack to organize dewars after drying, keeping the active rack free for the next cycle.
