LabExact Nylon Syringe Filters, 0.22 µm, 30 mm, 100/Pk - LE-IWT-ES10302

A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. The nylon membrane comes in a non-sterile format for routine analytical preparation while wetting on contact with aqueous buffers and delivers bacterial retention at the rated pore size. Low-extractable polypropylene keeps sample purity intact through the filtration pass while resisting degradation from routine sample matrices and presses snugly against the membrane during the pass. When sample preparation calls for a sterile filtrate at the point of injection, sterilizing-grade absolute retention delivers it directly, protecting the analytical method from microbial interference.

Membrane Characteristics

• Non-fibrous membrane structure resists media shedding into the filtrate
• Saturation moisture uptake reaches up to 8% by resin weight
• Hydrophilic surface takes up aqueous samples with no pre-wetting
• Ester- and alcohol-resistant across common laboratory sample preparations
• Non-sterile format suits HPLC and GC sample clarification

Housing Characteristics

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Polypropylene housing withstands rated backpressure from dense sample matrices without deformation
• Polypropylene housing tolerates dilute aqueous acids, bases, and alcohols used in routine sample prep
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Particulates in your buffers and mobile phases shorten column life and unsettle your baselines. Upstream buffer clarification keeps your run from stalling on particulates that slipped through while keeping the filtrate analytically clean.

• IC Column Protection - Clarifies aqueous samples ahead of anion and cation analysis, guarding ion-exchange columns against particulate fouling.
• Column Protection - Extends the life of analytical columns by reliably removing micro-particulates from aqueous mobile phases in HPLC.
• Drinking Water Analysis - Clarifies tap and source water samples ahead of metals, nitrate, and trace-contaminant compliance testing.
• UHPLC Sample Prep - Removes sub-micron debris from aqueous samples before injection, protecting narrow-bore UHPLC columns from accelerated wear.
• Mining Process Waters - Clarifies process water samples from hydrometallurgical operations, removing solids ahead of ICP-MS trace metal quantitation.
• HPLC Sample Prep - Clarifies mixed aqueous and organic solvents to ensure stable baselines and protect chromatography columns from clogging.
