Large discs, sheets, and rolls are suitable for industrial wastewater filtration, flat-sheet filtration, custom cutting, and test-strip production.
Use clean forceps to place the filter in the filtration device. Ensure proper edge sealing and pre-rinse with ultrapure water or sample solution when required. Add the sample slowly and collect either the filtrate or the filter according to the analytical method.
For trace analysis, include filter blanks and replicate samples to control background contamination.
For highly turbid samples, sedimentation, centrifugation, or coarse prefiltration is recommended before using GF/F. Avoid touching the filter directly to minimize contamination.
GF/F is intended for particle retention and analytical sample preparation. It is not a sterilizing-grade membrane.
GF/F low-chloride high-purity glass microfiber filters are designed for heavy metal testing, trace element analysis, environmental sample filtration, and ICP/ICP-MS sample preparation. Their low extractables, 0.7 μm retention rating, and wide range of formats make them suitable for both laboratory analysis and industrial processing.
