Laboratory Furnace Applications and Selections

Posted by Chia-yu Chen on

Furnaces have been a common equipment in laboratories. Furnace can be used for sintering, annealing, debinding, calcining etc. Different applications will require different functions of the furnaces such as the temperature range and furnace configurations. If the applications require inert gas, a furnace that allows introduction of gases is necessary. Types of furnaces include box furnace, muffle furnace and tube furnace.

MSE Supplies offers various types of furnaces such as muffle furnace, tube furnace and chamber furnace.

Muffle Furnace

Muffle furnace is a type of laboratory furnace that has ceramic muffle and is heated by conduction, convection or blackbody radiation from heating elements. It is often a box-type oven or kiln for high temperature applications. One of the applications is to determine the proportion of non-combustible and non-volatile material in a sample.

MSE Supplies offer various muffle furnaces.

1100°C

Heating

Encased in quartz glass

Muffle heated from four sides

Heating from two sides

Applications

Metal heat treatment, catalysts etc.

Aggressive gasses and vapors

Determining loss on ignition, ashing food and plastics for subsequent substance analysis.

Advantages

Fast heat-up rates

 

Ceramic muffle plates provide a good temperature uniformity and  protection of the heating elements from aggressive atmospheres.

High air exchange rate. Preheat incoming air for good temperature uniformity.

 

Tube furnace 

One of the main applications for tube furnace is to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis. In addition, tube furnaces can be used for coating, drying, hardening, annealing, degassing, sintering etc.

Tube furnaces consist of a working tube where sample is placed and heating elements which are around the working tube to optimize temperature distribution. Due to its precise temperature control, a laboratory tube furnace can be used for thermocouple calibration, crystal growth, fuel cells testing, or in catalyst research.

MSE Supplies offers different types of tube furnaces including split, rotary, horizontal and vertical types.
