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 verifies performance ratings at the lot level using process controls that stay uniform across its entire filtration lineup. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. Glass microfiber holds structural integrity through high-temperature conditioning cycles and stays biologically inert across diverse chemistries. Polypropylene construction maintains a low-dead-volume internal flow path while shedding virtually no extractable material into the sample and stays inert across common laboratory solvents. Where small-volume samples must reach the instrument clean, syringe filtration clears particulates in a single pass.

Technical Specifications

• Withstands autoclave steam sterilization at 121°C while maintaining structural integrity
• Suited for gravimetric fixed and volatile solids testing per Standard Methods 2540E
• Prefilters turbid samples ahead of standard microbial enumeration testing
• Clarifies protein-precipitated serum and plasma ahead of LC-MS/MS drug and metabolite quantification
• Suited for extractable matter determination in textile fibers and fabrics by Soxhlet extraction per ASTM D2257

Housing Specifications

• Standardized luer taper geometry provides secure engagement with standard syringe tips
• Injection-molded polypropylene housings accommodate threaded NPT and hose-barb port options beyond the standard luer taper
• Medical-grade polypropylene with broad chemical compatibility
• Dilute aqueous acids, bases, and alcohols used in sample prep do not degrade the polypropylene housing

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent.

• Hazardous Waste Testing - Meets EPA TCLP Method 1311 filtration specs for landfill leachate extracts in RCRA waste characterization testing.
• Dissolved Carbon Testing - Glass fiber's nominal 0.7 micron rating defines the standard operational cutoff for dissolved organic carbon analysis.
• Dissolution Testing - Clarifies pharmaceutical dissolution media of excipient particulates, protecting HPLC and UV assay systems from column fouling.
• High Load Prep - Delivers exceptional dirt-loading capacity for filtering difficult, particulate-laden samples without early clogging today.
• Pathogen Detection Prep - Clears turbidity from food and water samples ahead of Salmonella and Pseudomonas enumeration, preventing membrane clogging.
• Viscous Fluids - Supports rapid processing of suspension cultures and lysates that quickly foul standard membrane filters alone.
