Vacuum ovens are very versatile pieces of equipment with applications
in laboratory research, engineering and industry. Vacuum oven is
generally used for drying of substances which are hygroscopic and heat
sensitive and is based on the principle of creating a vacuum to decrease
the chamber pressure below the vapor pressure of the water causing it
to boil. It can be filled with inert gases, especially for rapid drying
of some compound material. The low pressure environment also minimizes
oxidation during drying.
The material to be dried is kept on
trays and pressure is reduced by means of vacuum pump. Steam is passed
through the space between trays and jacket, so that the heat transfer
occurs by conduction. The oven door is locked air tight and connected to
vacuum pump to reduce the pressure. Microprocessor controller with
digital display ensure precise and homogenous temperature control. Dual
layer tempered glass door is provided for clear observation. Adjustable
aluminum expansion shelves ensure optimal heat transfer within oven
chamber.
