Whatman Puradisc Nylon Syringe Filters, 1 µm, 25 mm, 1000/Pk - 6753-2510

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. Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. The nylon matrix handles alcohols and aliphatic and aromatic solvents while stopping particulates too coarse to pass its pore opening and wicks moisture into the disc on contact. Polypropylene construction resists chemical degradation from routine sample matrices while keeping sample purity intact through the filtration pass and maintains structural integrity through elevated-temperature sample preparation. 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

• Resonance-stabilized amide bonds anchor nylon's resistance to alkaline hydrolysis
• Solvent compatibility extends to both acetonitrile and methanol
• Low extractable contribution to sensitive analytical preparations
• Non-fibrous membrane structure resists media shedding into the filtrate
• Absolute pore size rating holds consistent across every protocol

Housing Specifications

• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Thermal-bonded construction keeps adhesives out of the fluid path
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics

A clean particulate separation keeps your aqueous sample preparation dependable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
