Borosilicate glass filters create a biologically inert filter matrix that is resistant to both chemicals and pH extremes. Use as prefilters to extend membrane life, for water/air pollution analysis, or liquid clarification. Filters without binder withstand up to 932°F (500°C); filters with binder withstand up to 250°F (120°C). Grades GC90, GS25, and DP70 with binder offer higher wet strength and lower fiber release.
Quartz fiber filters have very low trace metal content and can withstand up to 1832°F (1000°C). Choose quartz fiber filters to sample acidic gases at high temperatures or for air pollution analysis.
