Pura Disc 25mm GD2 GMF Syringe Filters, 2.0um, 100/Pk
Whatman SKU: 6783-2520

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 2 µm, 25 mm, 100/Pk - 6783-2520

Whatman standardizes its manufacturing platform to the point that consistency and thorough lot-level records come as a default, exactly what analytical laboratory work demands. Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. Glass fiber draws aqueous samples through without preconditioning while offering broad chemical compatibility and sustains high dirt-loading capacity through depth filtration. Polyolefin construction sheds virtually no extractable material into the sample while maintaining a low-dead-volume internal flow path and holds its seal true run after run. Where small-volume samples must reach the instrument clean, low hold-up volume keeps sample loss minimal while the instrument stays protected from particulate damage.

Technical Specifications

• Reduces bioburden and particulate load ahead of sterilizing-grade filtration
• Autoclave steam sterilization at 121°C leaves structural integrity intact
• Biologically inert borosilicate fiber with broad chemical compatibility
• Extends filterable sample volume three to seven times versus unprotected media
• Surface silanol groups attract water molecules for immediate aqueous wetting

Housing Specifications

• The seal formed against the membrane blocks bypass at rated operating pressure
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Translucent housing wall allows visual confirmation of sample flow during filtration

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day from reagent and buffer preparation through routine sample clarification.

• TOC Sample Filtration - Glass fiber prefilters aqueous samples ahead of total organic carbon analysis, removing particles without adding carbon.
• Viscous Fluids - Supports rapid processing of suspension cultures and lysates that quickly foul standard membrane filters alone.
• Pre-filtration - Acts as a robust depth filter that protects downstream membranes, significantly extending final filtration service life.
• Catalyst Sample Testing - Glass fiber removes fine catalyst particles from reaction product streams ahead of compositional and yield analysis.
• Wastewater Effluent Prep - Glass fiber removes suspended solids from industrial effluent ahead of COD, BOD, and nutrient compliance analysis.
• High Load Prep - Delivers exceptional dirt-loading capacity for filtering difficult, particulate-laden samples without early clogging today.
