Fast response from our specialists

Some analysis techniques may be affected by alumina or silica dust (Al2O3 and SiO2) – the materials normally used to construct furnace chambers.

To avoid this the GSM furnace chamber is constructed from a fused quartz material.

This design also offers superior containment of aggressive and corrosive vapours such as sulphuric, nitric and hydrochloric acids by keeping them away from the heating elements. Additionally if an optional gas inlet is specified, the enclosed design minimises gas leakages from the chamber.

Features:

1100 °C maximum operating temperature
v chamber, ideal for analyses where Al2O3 and SiO2 could contaminate test results
Chamber lining offers superior containment of corrosive & aggressive vapours such as H2SO4, HNO3, HCl
Moulded ceramic fibre door plug

Options (specify these at time of order):

Gas inlet for modified atmospheres (the fused quartz liner provides improved containment)
Sample trays & racks
A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications
