LabExact PTFE Syringe Filters, 0.45 µm, 13 mm, 100/Pk - LE-IWT-ES10035

Sample preparation for chromatography often ends with a syringe filter on the path to the vial. The PTFE membrane clarifies solvent streams at the rated pore size and accepts aqueous samples without alcohol pre-wetting. The polypropylene housing holds its seal true run after run while staying inert across common laboratory solvents and maintains a low-dead-volume internal flow path. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Membrane Characteristics

• Membrane integrity holds across repeated autoclave sterilization cycles at 121°C to 134°C
• Biological inertness resists enzymatic attack from proteases and lipases
• Low non-specific protein binding preserves recovery of biomolecules and therapeutic proteins during filtration
• UL 94 V-0 rating confirms the highest self-extinguishing classification
• Inert composition offers no nutrient source for microbial growth

Housing Characteristics

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Polypropylene housing withstands rated backpressure from dense sample matrices without deformation
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening

A particulate-laden aqueous sample makes the rest of your preparation unpredictable. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods.
