Pura Disc 13mm GF/C GMF Syringe Filters, 1.2um, 100/Pk
Whatman SKU: 6822-1312

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 1.2 µm, 13 mm, 100/Pk - 6822-1312

Whatman maintains in-house specialists who set and verify material specifications separately for its cellulose, glass-fiber, and polymer membrane chemistries, tailoring quality control to how each one behaves in use. A syringe filter's small hold-up volume limits sample loss, a meaningful difference when working with a limited or precious sample. The glass microfiber matrix accepts water-based samples on contact and resists chemical attack across diverse solvents. The PP housing stays inert across common laboratory solvents and buffers in routine use while leaving no seam for sample to bypass the membrane and keeps the sample chemically unaltered across the pass. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Technical Specifications

• Autoclave steam sterilization at 121°C leaves structural integrity intact
• Biologically inert borosilicate fiber with broad chemical compatibility
• Inorganic construction suits demanding sample-preparation chemistries
• Surface silanol groups attract water molecules for immediate aqueous wetting
• Extends filterable sample volume three to seven times versus unprotected media

Housing Specifications

• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Optimized internal geometry minimizes backpressure in service
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it.

• Analysis Prep - Ensures reliable clarification in multi-stage filtration stacks, effectively removing gross debris and precipitates safely.
• Environmental Prep - Clarifies wastewater and soil analysis extracts efficiently, preventing premature clogging of finer analytical membranes.
• High Load Prep - Delivers exceptional dirt-loading capacity for filtering difficult, particulate-laden samples without early clogging today.
• Bioanalytical Prep - Clears precipitated plasma and serum proteins ahead of LC-MS/MS assay, protecting columns and autosampler needles.
• Cannabis Extract Analysis - Glass fiber removes lipid and plant wax particulates from cannabis extracts ahead of cannabinoid potency testing.
• Heavy Metal Digests - Glass fiber removes undissolved particulates from acid-digested soil and water samples ahead of ICP and AAS analysis.
