Pura Disc 13mm GF/D GMF Syringe Filters, 2.7 um, 100/Pk
Whatman SKU: 6823-1327

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 2.7 µm, 13 mm, 100/Pk - 6823-1327

Whatman's filtration expertise, refined across a century-plus of disciplined manufacturing, has made its name synonymous with laboratory-grade quality worldwide. Many syringe filters ship with lot-specific quality documentation, giving analysts traceability that an ad hoc bulk filtration setup typically lacks. The glass microfiber matrix accepts water-based samples on contact and offers broad chemical compatibility. The polypropylene housing routes flow to minimize backpressure in service and holds its seal true run after run. Where analytical results depend on clean samples, the preparation step stays consistent from sample to sample through a pre-tested syringe filter.

Technical Specifications

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

Housing Specifications

• Dilute aqueous acids, bases, and alcohols used in sample prep do not degrade the polypropylene housing
• Translucent housing wall allows visual confirmation of sample flow during filtration
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure.

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods. Standardize your filtration purchases across every method with volume pricing and documentation from the Tisch Scientific team.

• Analysis Prep - Ensures reliable clarification in multi-stage filtration stacks, effectively removing gross debris and precipitates safely.
• Sediment Porewater Prep - Glass fiber removes mineral and organic fines from sediment porewater samples ahead of ion and metals analysis.
• Tissue Culture - Clarifies tissue homogenates and cell lysates with ease, protecting finer downstream membranes from early blockage.
• Water Analysis - Delivers high retention efficiency for suspended solids in water quality testing, ensuring accurate environmental reporting.
• Wastewater Effluent Prep - Glass fiber removes suspended solids from industrial effluent ahead of COD, BOD, and nutrient compliance analysis.
• Pre-filtration - Acts as a robust depth filter that protects downstream membranes, significantly extending final filtration service life.
