产品介绍
Glass fiber filters meet all preparation requirements in Standard Methods for procedures 2540D and 2540E. Use in Total Suspended Solids and other gravimetric analyses.
- Only routine blank testing is required; no equivalency testing necessary
- After washing, drying and desiccation, filters are weighed to the nearest 0.1mg on certified electronic analytical balances
- Weights are printed on heat-resistant Mylar™ labels affixed to convenient aluminum pans
- 8% of all ProWeigh filters are redried and reweighed to ensure weight stability
- DoubleWeigh™ filters are 100% tested to ensure weight stability to within 0.5mg
- ProWeigh filters for Volatile Solids (09-735-57) are recommended when measuring fixed or volatile solids—they're heated to 550°C (1022°F) in a muffle furnace to drive off volatiles, then desiccated and weighed
