GLASS FIBER FILTER DATA
Glass Fiber Filters are
especially recommended wherever gravimetric weighing analysis
may be required because of their non-hygroscopic properties,
i.e. they will maintain constant weight under wide-ranging
conditions of ambient humidity. Their excellent loading
characteristics make them ideal for routine air monitoring and
for specialized monitoring of solid pollutants, microrganisms,
oil and acid smokes etc. They are particularly recommended where
higher efficiency collection of fine particles is required. They
exhibit higher particle capacity then cellulose filters. Their
fine optical characteristics make them ideal for sensitive and
accurate measurement of collected smoke particle. Used
especially for on-the-spot visual examination and
instrumentation. Glass Fiber Filters have a higher density
then paper filters and can tolerate a far wide useful
temperature range.
Composition of the Glass Fiber
Filter is of such a nature that the finely woven texture of
microfilaments of glass creates the highest sampling efficiency.
The efficiency of the Glass Fiber Filters at the relative flow
rate for particles as small as .3 micron is 99.98%.
Staplex Glass Fiber Filters are
binderless (i.e. they do not contain organic binders). The heat
resistance is up to approximately 470-490 degrees C.
