Product Description

Efficiency for Daily Lab Routine: Designed for non-sterile laboratory applications, these PES filters offer the fastest flow rates for aqueous solutions. The yellow housing ensures easy identification among other membrane types, reducing errors during high-pressure workflows.

Maximum Sample Recovery: The naturally hydrophilic PES membrane features ultra-low protein binding, ensuring that your valuable analytes pass through without loss. It is the ideal choice for HPLC sample preparation, environmental testing, and general filtration where sterility is not required.

Applications

Designed for rapid filtration in non-sterile analytical environments

HPLC/GC Sample Pre-filtration

General Aqueous Buffer Filtration

Environmental Water Quality Analysis

Protein Analysis (Non-sterile)

Particle Removal from Biological Fluids

FAQ

What are the main benefits of non-sterile PES filters?

They are more cost-effective for routine analytical tasks like HPLC sample prep where the sample is not for cell culture or sensitive biological use.

Can I autoclave these non-sterile filters?

Yes, our PES filters can be autoclaved at 121°C if a sterile environment is occasionally required for your specific test.

Is the yellow housing chemical resistant?

The housing is made of medical-grade PP, which has excellent resistance to most acids, bases, and aqueous-based laboratory reagents.

When should I use 13mm vs 25mm filters?

Choose 13mm for sample volumes <10mL to minimize loss; use 25mm or 33mm for volumes 10-100mL to prevent clogging and increase speed.

Are these filters suitable for protein recovery?

Absolutely. PES is known for its ultra-low protein binding, making it the best non-sterile choice for filtering protein-containing solutions.
