LabExact Polypropylene (PP) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10131

Sample preparation for chromatography often ends with a syringe filter on the path to the vial. Low-binding polypropylene sustains throughput as a depth medium while tolerating solvents and acids that degrade many membranes and combines water-repelling character with wide chemical durability. The polypropylene housing holds its seal true run after run and sustains efficient flow on viscous samples. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Membrane Characteristics

• Compatible with dilute acids, ketones, and aliphatic esters at room temperature
• Broad solvent tolerance includes glycols, aliphatic alcohols, and dilute salt solutions
• Saturated hydrocarbon backbone resists the hydrolytic degradation common in ester-linked filter media
• Withstands repeated steam autoclave cycles at 121°C without structural degradation
• Metal-ion leaching resistance holds during acid-digested sample filtration

Housing Characteristics

• Plasticizer-free polyolefin construction keeps the fluid path clean
• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Rated operating pressure supports filtration of high-resistance and viscous samples without housing distortion
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening

An aggressive solvent can leach or break down a vulnerable filter and carry debris into your prep. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use. Standardize your filtration purchases across every method with volume pricing and documentation from the Tisch Scientific team.
