LabExact Nylon Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10235

Because each syringe filter is dedicated to one sample, a failed or contaminated filtration stays isolated to its own analyst's run and leaves the next analyst's queue clear. The nylon membrane holds dimensional stability under rated backpressure while tolerating alcohols and aliphatic and aromatic solvents and fits routine analytical sample preparation. The polypropylene housing holds its seal true run after run while resisting degradation from routine sample matrices and maintains a low-dead-volume internal flow path. 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.

Membrane Characteristics

• Saturation moisture uptake reaches up to 8% by resin weight
• Layered prefiltration sustains flow through turbid, particulate-laden samples
• Amorphous-crystalline nylon blend composition doubles membrane burst strength over homopolymer nylon
• Resonance-stabilized amide bonds anchor nylon's resistance to alkaline hydrolysis
• Non-sterile format suits HPLC and GC sample clarification

Housing Characteristics

• Minimal extractable release from the housing supports sensitive analytical work downstream
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening
• The seal formed against the membrane blocks bypass at rated operating pressure
• Polypropylene housing withstands rated backpressure from dense sample matrices without deformation

Juggling several filter types for one routine clarification eats up your bench time. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows. Standardize your filtration purchases across every method with volume pricing and documentation from the Tisch Scientific team.

Sterilization Guidance

Standard autoclave cycles at 121°C for 30 minutes prepare the device for sterile workflows.
