Vacuum oven VO series


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


Celsius Software - Secure programming and documentation included

The Memmert Celsius software for convenient and extensive programming and documentation of processes is included with every heating oven of the Perfect class, and for every CO2 incubatorvacuum drying ovenclimatic test chamber and humidity chamber – for an added charge, it is also available as an FDA version. For all ovens of the Perfect class the Celsius software, including the instruction manual, can be downloaded here.


Simple programming and reading out the data logger

The Memmert Celsius software runs on Windows 7, Vista and XP, and can be set to the languages German, English, French, Spanish or Italian. Convenience, safety, time savings and a clear presentation are the main advantages for the user: Each process chart can be given a legend for individual process parameters and the zoom functionprovides a way to view details from the graphically presented process sequences at any position you want. Thereport function saves log files in tabular form and analyses them automatically with minimum, maximum and average values. At the same time, the numerical output of sequences takes place directly via printer or via export to Excel. In Addition, the data from the internal controller data logger are saved automatically each day.
