Vacuum ovens, cooled, VOcool series

Supplier: Memmert
Using low temperature vacuum drying sensitive and unstable samples can be dried gently, avoiding damage to the cell structure. These cooled vacuum ovens have corrosion resistant, stainless steel inner chambers and housing. Direct contact between the load and thermoshelf ensures rapid and equal heating/cooling without thermal loss. The thermoshelf has a PT100 temperature sensor at the centre with integrated large-area heating and cooling in the lowest position (cannot be removed). This gives excellent thermal transition, very fast heating-up/cooling down times and precise control. Units feature an auto diagnostic system with fault indication. GLP/GMP compliance is assisted via the parallel interface and "Celsius" software for control and documentation of temperature and pressure. Internal log memory records all setpoint and actual values.

  • Digital LED display for all set and actual parameters and digital seven-day programme timer with real time clock
  • Integrated timer for temperature and pressure (vacuum) profiles of up to 40 ramps, each segment is adjustable from 1 min up to 999 h
  • Various protection features including digitally adjustable, microprocessor over-temperature controller TWW, (independent adjustable temperature safety device class 3.1, which protects the samples and the oven) maximum value for over-temperature, minimum value for under-temperature with audible and visual alarm
  • Adjustable pressure range 10 mbar up to 1100 mbar
  • Glass door, with a spring-loaded, 15 mm thick safety glass panel inside and a non-splinter screen on the outside
  • Temperature range extension from 0 to +90 °C is available as a factory fitted option

IP protection class according to DIN EN 60529: IP 20

Delivery information: Units supplied with bottom drip tray, software and one fixed thermoshelf with a calibration certificate (measurements taken at 50 °C and 50 mbar in the middle of the shelf), pump control, inert gas inlet. Additional accessories and factory fitted options are available on request, please enquire for further details. Note, units have a 3 year warranty period as standard. The optional additional 1 year extension to that 3 year period, gives 4 years in total.
