Cooled vacuum oven VO29cool
For gentle drying of bacteria and starter cultures or simulation of intercontinental flights.
Standard delivery Cooled vacuum oven
The direct contact between the load and the heatable thermoshelves in the chamber of the vacuum oven ensures rapid and uniform temperature control of food, cosmetics, watches, books, PCBs or injection moulds, without the loss of heat.
