LabExact Polypropylene (PP) Syringe Filters, 0.45 µm, 25 mm, 100/Pk - LE-IWT-ES10136

Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. The polypropylene membrane holds up to aggressive process chemistries and stays well suited to solvent-rich, non-aqueous specimens. Polypropylene housing is factory-sterilized and packaged to preserve that state until use while keeping sample purity intact through the filtration pass and sustains efficient flow on viscous samples. 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

• Extractable levels remain very low across the depth matrix
• Dense polypropylene fiber network intercepts fine particles through the full medium depth
• Nominal pore ratings span submicron prefilter grades to coarse depth configurations
• Broad solvent tolerance includes glycols, aliphatic alcohols, and dilute salt solutions
• Flexible polypropylene fiber matrix adapts to modest pressure cycles without fracture

Housing Characteristics

• Resists stress cracking from aqueous salt and buffer solutions
• Impact-tolerant polypropylene body withstands routine bench handling without damage
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening

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.
