Sterile PP Syringe Filter, 0.45µm, 13mm, Hydrophobic Membrane, Luer-Lok, 100/Pk
LabExact SKU: LE-IWT-ES10134

LabExact Polypropylene (PP) Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10134

Many syringe filters ship with lot-specific quality documentation, giving analysts documented traceability beyond what an ad hoc bulk filtration setup typically provides. Polypropylene tolerates solvents and acids that degrade many membranes and combines water-repelling character with wide chemical durability. Thermal-bonded PP construction leaves no seam for sample to bypass the membrane and resists degradation from routine sample matrices. When chromatographic methods demand particle-free injections, the column stays clean from run to run, protecting method performance and column life.

Membrane Characteristics

• Compatible with dilute acids, ketones, and aliphatic esters at room temperature
• Broad solvent tolerance includes glycols, aliphatic alcohols, and dilute salt solutions
• Captures coarse particles near the surface and fine particles deeper within
• Nonpolar surface chemistry favors organic solvents and other non-aqueous liquids
• Halogen-free composition avoids hazardous fluorine byproducts during incineration

Housing Characteristics

• Thermal-bonded construction keeps adhesives out of the fluid path
• Polypropylene housing tolerates ethylene oxide gas sterilization cycles without softening or dimensional distortion
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• PP housing supplied sterile in individual packaging for immediate use in aseptic filtration without bench preparation

Particulates left in your organic solvents and reagents carry downstream into the step that depends on a clean feed. Reliable solvent prefiltration keeps a stray particulate from carrying into your downstream work so your downstream method starts with a clean sample.
