Description
The unique integral nozzle design reduces weight and breakage. The entire assembly is lightweight and uses no O-rings which allows for testing at much higher temperatures.
Quartz filter assemblies are available for testing in temperatures up to 1000°C.
We offer two different filter media (glass and quartz). The thimbles are seamless, high-purity filters, tapered for ease of loading. The gas collection efficiency of the thimbles is 99.9% (%0.3 mm DOP). The thimble filter media comes in boxes of 10.
GFA-2590-K – Glass fiber thimble, 25 x 90 mm, max 500°C. These borosilicate glass fiber thimbles are acid-washed to reduce the trace metal content to an absolute minimum.
GFA-2590Q-K – Quartz fiber thimble, 25 x 90 mm, max 1000°C. Silica fiber thimbles are strengthened with alumina and are pre-fired at 900°C for 2 hours during manufacturing to stabilize the weight prior to use.
