The Glass and Quartz filter range from Munktell is now available in the UK and Ireland from Anachem.
Glass fibre filters are manufactured from borosilicate glass and are bound by synthetic binders.
The use of fine fibres provides high efficiency rates down to submicronic levels combined with high direct holding capacity and good air permeability.
This filter media is compatible with a large number of inorganic and organic solutions and is physically and biologically inert.
Micro-glass fibre filters with binders resist temperatures up to 180C and can be used for air-pollution control with or without chemical analysis, measurement of smoke-spot number, as well as exhaust emission tests.
The cylindrical glass fibre thimbles can be used for the retention of particulate dusts and aerosols from gas or air streams.
They have a high temperature resistance and the same chemical resistance as glass fibre filters.
These thimbles are the solution when condensation, water or oils have to be separated from compressed air, gases or exhaust air for analytical or technical purposes.
Quartz fibre filters without glass fibre and binders are used for emission control at high temperatures of 900-950C and wherever absolute purity of the filter medium is required.
These filters present filtration properties with minimal metal contents, plus weight and dimensional stability.
Unlike micro-glass fibre filters, they can also be used for the analysis of acidic gases.
The Glass and Quartz filters are available as circular filters, sheets, reels or thimbles in a variety of sizes and thickness.
A range of GE PTFE membrane filters that can be used to protect air-monitoring apparatus are also available from Anachem.
