Cellulose Qualitative Filter Paper, Grade 93, 43-48um Retention, 90mm, Very Fast, 100/Pk
GVS SKU: FP090DME93QALC01

Featuring a refined cellulose depth medium with a 43 to 48 micron retention range, this Grade 93 qualitative filter paper delivers very fast filtration for routine laboratory separations. Each 90mm circle measures 170 microns thick with a nominal basis weight of 80 g/m2 and a low ash content of less than 0.1%, providing dependable clarification of coarse to medium particulates without compromising flow.

Key Cellulose Media Characteristics

• Hydrophilic cellulose structure that wets readily and supports rapid, even flow across the disc
• Nominal particle retention of 43 to 48 microns for capturing coarse and medium particulates
• Very fast filtration speed suited to high-throughput routine work and clarification of liquids
• Low ash content of less than 0.1% for qualitative analytical separations
• Depth medium offering generous dirt-holding capacity for heavily loaded samples

Key Construction Characteristics

• Circular disc format with a diameter of 90mm
• Nominal thickness of 170 microns
• Nominal basis weight of 80 g/m2
• Qualitative grade, supplied nonsterile
• Packaged 100 discs per box

This filter paper maintains consistent flow and clean separation across repeated use, helping preserve sample integrity during routine clarification and gravimetric prep. The fast, uniform medium reduces filtration time while reliably removing particulate from aqueous and common laboratory liquids.

• Liquid Clarification Removes coarse to medium particulates from cloudy aqueous samples and laboratory liquids for clearer filtrates.
• Qualitative Analysis Supports routine qualitative analytical separations where residue weight accuracy is not required.
• Sample Prefiltration Protects downstream membranes and instruments by capturing larger particulates ahead of fine filtration.
• Soil and Environmental Sample Prep Filters soil extracts and environmental samples for routine monitoring and analysis.
• Food and Beverage Testing Separates solid foodstuffs from associated liquids during general laboratory food analysis.
• General Laboratory Filtration Handles high-throughput, less-critical filtration tasks thanks to its very fast flow rate.
