Vacuum oven VO

Drying food, cosmetics, clocks, books, PCBs or injection moulds: Design your own VO vaccuum oven according to your wishes!

Vacuum oven

Vacuum drying oven VO the gentle giant in the laboratory

With short warming up times, high-precision temperature control and turbo-drying, the vacuum oven VO shows off all its strength – at the same time it can handle heat-sensitive or oxygen-sensitive substances and materials such as cosmetics, food, clocks, books or PCBs and other electronic components with unparalleled gentleness when drying. The direct contact between chamber load and the heatable and removable thermal shelves guarantees in all vacuum oven VO models a quick and even temperature control without loss of heat. Because of the direct contact between heating and chamber load, the heating and operating times in the vacuum drying oven VO are reduced by some 75 per cent compared to a conventional drying oven.
  • Temperature range up to +200 °C
  • 3 model sizes (29 to 101 litres volume)
  • State-of-the-art control technology based on the P performance class for all models
  • Anti-splinter; VDE-tested door construction for all models
  • Pump control: Optimised rinsing procedures for pump membranes as needed, as well as signal output for pumps ON/OFF

Premium options in the Premium module

For elaborate applications a Premium module can be chosen, with its content depending on the model size. Apart from the option of inert gas inlet, the Premium module also contains one (VO 200) or two (VO 400, VO 500) additional connections for thermoshelves, as well as an extra thermoshelf (only VO 400 and VO 500), a drip tray and the printer port.

Considerably shorter heating and processing times in the vacuum 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.

Aluminium thermoshelves for optimum temperature distribution

To achieve an optimum temperature distribution on all separately heated levels in the chamber, the thermoshelves for our vacuum drying oven are made of anodised and surface-enhanced aluminium as standard. For applications with highly corrosive materials we optionally recommend that you choose stainless steel thermoshelves because of their resistance to chemicals.

A Memmert vacuum drying oven offers unique advantages

  • heating concept specifically adapted for a precise and homogenous temperature control
  • Up to 40 ramps with different temperature and vacuum setpoints can be programmed either directly on the controller or using the MEMory-Card. The ”Celsius“ software provides a practically unlimited number of ramps.
  • almost exclusive use of high-quality, corrosion-resistant and easily cleanable stainless steel for the working chamber and housing.
