Laboratory Furnaces

Bottom loading furnaces are designed for uniform thermal distribution inside the chamber, easy loading and unloading of the sample with help of lifting arrangement. Bottom loading furnaces are ideal to achieve a variety of heating-cooling cycles without sacrificing temperature uniformity or product quality. These furnaces are well suited for calcining, firing and sintering oxide ceramic parts (i.e., alumina, zirconia), technical ceramics, co-fired substrate materials, capacitors, filters, thermistors, ferrites.

The high-temperature bottom loading furnace sare additionally equipped with a drying as well as a forced cooling function. For residual drying, the oven remains open gapwise during heating up to a defined temperature and thus ensures reliable removal of moisture. For accelerated cooling, the furnace is automatically opened step by step under program control.

Dental Furnace is a bottom loading type heat treatment equipment used to change the physical properties of samples at very high temperatures. These laboratory furnaces are widely used in scientific experiments in dental laboratories. Its major applications are in sintering translucent zirconia and dental ceramics operations. This furnace provides the following advantages: easy loading and removal of samples like molten glass, dental zirconia, etc. furnace uses an electrically operated elevator hearth, which as it rises into the furnace chamber, lifts the load into the heated zone.

Standard Features

• Max Operating temperature 1100°C
• Bottom loading type furnace
• Multiple Programmable PLC automatic controllers
• Display̵ LED display
• Easy operation and maintenance
• Outstanding temperature uniformity inside the chamber

High-temperature furnaces are another type of laboratory furnace capable of reaching higher temperatures between 1400°C up to 1800°C. A high temp furnace typically consists of heating elements located on both sides of the heating chamber to ensure good thermal uniformity. Process applications for a high-temperature furnace include sintering of high-temperature materials, glass melting, and high-temperature testing of ceramics, fusion and firing processes, and powder metallurgy processes.

High-temperature furnaces are insulated with fibre material. Furnaces with fibre insulation achieve significantly shorter heating up times because of the low thermal mass.
