Pura Disc FP 30mm CA Syringe Filter, 0.45um, Sterile, 500 Pk
Whatman SKU: 10462600

Whatman Puradisc Cellulose Acetate (CA) Syringe Filters, 0.45 µm, 30 mm, 500/Pk - 10462600

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. Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Cellulose acetate binds BSA at 3.8 micrograms per square centimeter while keeping filtrate clean ahead of analysis and relies on hydroxyl chemistry alone, no coating needed. The polycarbonate housing supports everyday aqueous filtration workflows while closing tightly enough that sample only exits through the membrane and supports demanding high-pressure filtration. For routine sample preparation across many methods, the syringe filter folds clarification into one disposable step.

Technical Specifications

• Cellulose acetate's open pore structure supports high flow rates at low operating pressure.
• Tolerates methanol and ethanol at typical laboratory working concentrations
• Accepts gamma irradiation or ethylene oxide exposure as alternative sterilization methods to autoclaving
• Naturally hydrophilic surface wets readily with aqueous samples
• Retains particles at the membrane surface instead of throughout its thickness

Housing Specifications

• Elongation at break lets the housing yield instead of shattering under overload
• Sustains high operating pressures without deformation
• Flexural rigidity resists housing collapse under vacuum-driven filtration
• High-impact-strength housing resists cracking under demanding handling

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 from the first sample of the day through the last.

Hydrophilic

• Groundwater Analysis - Separates the dissolved fraction of environmental water samples ahead of trace metal analysis by ICP-MS or ICP-OES.
• HPLC Sample Prep - Clarifies injection samples and mobile phases ahead of LC analysis, protecting columns from particulate fouling.
• Protein Recovery - Maximizes yield of target proteins by minimizing nonspecific binding, preserving valuable biological samples.
• UV Spectroscopy Prep - CA's naturally hydrophilic, low-binding surface avoids analyte loss during sensitive UV-Vis sample prep work.
• Diagnostic Assays - Delivers reliable results in enzymatic tests by limiting adsorption of active reagents to the membrane surface.
• Beverage Clarification - Removes haze-causing particulates from wine, beer, and juice samples ahead of quality and stability testing.
