LabExact Polypropylene (PP) Syringe Filters, 0.22 µm, 25 mm, 100/Pk - LE-IWT-ES10130

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. Polypropylene tolerates solvents and acids that degrade many membranes while sustaining throughput as a depth medium and combines water-repelling character with wide chemical durability. The polypropylene housing presses snugly against the membrane during the pass and resists degradation from routine sample matrices. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Membrane Characteristics

• Sustains throughput on particulate-laden solvent samples
• Polyolefin structure resists saponification under prolonged base contact
• Aqueous liquid is repelled while air passes freely through
• Saturated hydrocarbon backbone resists the hydrolytic degradation common in ester-linked filter media
• Solvent-stable polypropylene handles aliphatic hydrocarbons and common process oils

Housing Characteristics

• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Optimized internal geometry minimizes backpressure in service
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening

A filter that softens or swells in your solvent fails you mid-run, batch after batch. Solvent-stream filtration handles the solvents and reagents your methods rely on from initial prep through final use. Request a quality certificate, lot documentation, or a blanket-order quote for your filtration order at any time.

Sterilization Guidance

The housing supports customer autoclave sterilization at 121°C for 30 minutes.
