Chamber Furnaces for Ashing and High Temperature Use

Carbolite chamber furnaces are used for heat treatment of larger samples of materials so as to change their

physical or chemical properties. Ashing furnaces have been designed to provide the optimum conditions to

ash samples, without damaging effects upon the furnace. In addition to versatile general laboratory products

Coal & Coke, Precious Metals Assay, Asphalt Binder Analysis through loss on ignition, and many other applications.

VOLUME

The Carbolite product range comprises chamber furnaces and ovens from as small as one litre up to 10,000 litres and tube furnaces with heated lengths from as small as 130 mm up to several metres.

For 75 years Carbolite products have been the instrument

of choice for research, testing and production processes

worldwide. Carbolite offers an unmatched level of choice from

standard product ranges and accessories or by customisation

scheme and are designed to comply with the EU Low Voltage

and EMC directives and carry the CE mark.

The two most important factors for selection of the correct

product are the task and the temperature range. For small

sample size and good temperature uniformity, tube furnaces

are the best choice. Tube furnaces also make it easier to collect

volatiles or to work under controlled atmospheres. For larger

sample volumes a chamber furnace may be more appropriate.

Tube Furnaces The Ideal Choice to Heat Small Samples

Where sample volumes are quite small or a high degree of uniformity is required, tube furnaces are a good

choice. When selecting a tube furnace in addition to the operating temperature other important factors

are needed, the heated length and the diameter. Some tube furnaces have the element wound directly

on the worktube while other ranges require the addition of a separate worktube unless the sample is to

be directly heated in an application such a tensile testing. This type of work is often easier if a split tube

design is chosen. Accessories are available to work with vacuum or the addition of gas to the tube.

The MTF series is suitable for heating small samples with a high degree of uniformity, especially where volatile materials need to be captured for analysis or an atmosphere other than air is required.
