Carbolite Gero – Laboratory Chamber Furnace
Carbolite Gero’s extensive chamber furnace range has a maximum operating temperature of 1800°C and chamber capacities up to 725 liters. They are suitable for a variety of laboratory, pilot scale and industrial applications. Although there is flexibility in size and temperature, if the application requires the use of modified atmosphere (above 1100°C) or vacuum then a furnace from Carbolite Gero’s tube furnace range should be selected.
An extensive range of chamber / muffle furnaces is available for your laboratory.
Whether you need a small bench mounted affordable solution or a high temperature furnace built to the highest quality, Carbolite Gero has a model that is sure to meet your needs and budget. Ranging from the entry level ELF models at 1100°C through to the laboratory sized HTF model with a maximum temperature of 1800°C our experience of building quality furnaces for customers around the globe over the last eight decades has ensured that the Carbolite Gero name is synonymous with Leading Heat Technology.
Whether you need a front, top or bottom loading chamber furnace our extensive portfolio virtually guarantees there is an appropriate standard solution that will meet your requirements but of course our bespoke design service allows us to meet almost every scenario we have ever been consulted about.
