GD/X 13mm Syringe Filter, Cellulose Acetate Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6880-1302

Whatman GD/X Cellulose Acetate (CA) Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6880-1302

Whatman places a fibrous glass mat before the final membrane in every GD/X device, clearing a turbid sample in one pass through the same housing. Sterilizing-grade syringe filters deliver sterile-grade retention as a single-use format, eliminating the autoclaving and cleaning cycle a reusable sterile filtration setup would require. Low-binding cellulose acetate provides sterile-grade retention with high recovery while keeping filtrate clean ahead of analysis and shield the polymer chains from direct protein adsorption. The polypropylene housing presses snugly against the membrane during the pass while holding its form through high-temperature sample preparation conditions and stays inert across common laboratory solvents. Where bacterial contamination must stay out of the sample, manufacturer-tested retention keeps the instrument and downstream assay protected without a housing to maintain or clean.

Membrane Characteristics

• Stable in aqueous saline, buffer, and protein solution matrices
• Biologically nontoxic cellulose ester provides a clean filtration surface
• Smooth membrane face with even pore distribution across the active filtration area
• Dilute samples retain their true, unadsorbed concentration through the membrane
• Naturally hydrophilic surface wets readily with aqueous samples

Housing Characteristics

• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• The seal formed against the membrane blocks bypass at rated operating pressure
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.
• Resists stress cracking from aqueous salt and buffer solutions

Reproducible separations start with samples that reach the column free of particulates. Upstream sample clarification keeps your separations clean and reproducible across your HPLC and UHPLC methods.

• Ophthalmic Formulation Prep - Low-extractable CA filters ophthalmic solutions ahead of quality testing and release without contributing contaminants.
• Urinalysis Prep - CA clarifies urine samples by removing particulates ahead of automated urinalysis without altering biochemical composition.
• Beverage Clarification - Removes haze-causing particulates from wine, beer, and juice samples ahead of quality and stability testing.
• Dissolution Testing - Clarifies drug-release samples of undissolved particulates pulled from dissolution vessels, ensuring accurate potency results.
• Protein Recovery - Maximizes yield of target proteins by minimizing nonspecific binding, preserving valuable biological samples.
• Biological Solutions - Offers a stable, hydrophilic membrane for sensitive aqueous fluids, letting critical analytes pass through freely.
