Laboratory Chamber Furnaces

Wide range of furnaces
THERMCONCEPT laboratory chamber funaces are available in sizes from 5 litres to 45 litres (see Technical Data). The inner dimensions and maximum operating temperatures are adapted to the needs of laboratories. Our range of furnaces also includes models with a Voltage of 230 V.

Accessories
Due to many different accessories and extras our laboratory chamber furnaces can be adapted to individual needs and applications:

Vent with / without fan
Vent with fan and catalytic converter
Adjustable temperature limiter to protect furnace and charge acc. EN 60519-2
Protective gas connection at the rear side
Further accessories see furnace accessories

With moveable bottom
Laboratory chamber furnaces can be also supplied with manually moveable furnace bottom to charge the bottom easily outside the furnace. Available for all chamber furnaces with a temperature range up to 1100 °C, 1200 °C and 1300 °C.

With integrated air circulation
Laboratory chamber furnaces can be supplied optional with fan for integrated air circulation. This air circulation system increases heat transfer from heating elements to the charge and temperature uniformity inside the chamber. Chamber furnaces with integrated air circulation are available for a maximum temperature of 1100 °C.
