Whatman Puradisc Nylon Syringe Filters, 0.1 µm, 13 mm, 100/Pk - 6789-1301

Whatman has built such a strong track record in published methods that laboratories default to citing its name in standardized protocols. A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. Nylon wets on contact with aqueous samples while supporting high-volume routine filtration and reaches bacteria-retentive performance across sub-micron pore range. The polypropylene housing keeps the sample chemically unaltered across the pass while holding its seal true run after run 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.

Technical Specifications

• Moisture-plasticized amide linkages raise membrane impact toughness over dry resin
• Non-sterile format suits HPLC and GC sample clarification
• Tortuous, reticulated pore structure yields more usable filtration area than capillary-pore membranes
• Alkaline-resistant across a broad range of aqueous buffers
• Common ketone solvents, including acetone, methyl ethyl ketone, and methyl isobutyl ketone, cause no attack

Housing Specifications

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Thermal-bonded construction keeps adhesives out of the fluid path
• Dilute aqueous acids, bases, and alcohols used in sample prep do not degrade the polypropylene housing
• PP housing rated to 121°C holds its geometry through high-temperature sample preparation and processing.

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.
