Engineered for gentle handling of heat- or oxygen-sensitive materials: heatable and removable thermal shelves guarantee a quick and even temperature control without loss of heat. The basic facts: Temperature range up to + 200 °C, chamber volume 29, 49 and 101 litres.

Each of the maximum, up to four, aluminium thermoshelves that can be inserted as required is equipped with a separate shelf heating and its own sensors. Because of the direct contact between thermoshelves and chamber load, the heating and operating times in the vacuum drying oven VO are reduced by some 75% compared to a conventional drying oven.

If large amounts of powder and granulate need to be dried in the vacuum oven, the vacuum cycles, offered exclusively by Memmert worldwide, come into play: Two vacuum values can be set, between which the pressure is oscillated under controlled conditions. This way, a large amount of dry air is admitted within a short time, which absorbs humidity and is immediately extracted by the vacuum pump.
