Syringe Filters PVDF Hydrophilic 25mm 0.22µm Labfil Pack of 20

Description

Product Overview

The Labfil Syringe Filters are engineered with a premium polyvinylidene difluoride (PVDF) hydrophilic membrane that provides a precise 0.22 µm pore size. This membrane offers broad chemical compatibility while minimizing protein binding, making it an excellent choice for applications where high protein recovery is essential. The filters are sized for a 25 mm syringe, allowing easy integration into standard laboratory workflows. Each filter includes a female Luer inlet and a male slip Luer outlet, ensuring a secure, leak‑free connection that meets industry standards for micro‑filtration.

Usage

These syringe filters are ideal for a wide range of laboratory scenarios, including purification of cell culture supernatants, preparation of samples for chromatography, and removal of particulates from biological fluids. Researchers in biochemistry, molecular biology, and pharmaceutical development can rely on the consistent performance of the PVDF membrane to protect downstream analytical instruments. The filters are compatible with most aqueous solutions, but users should avoid strong acids, bases, esters, ethers, or ketones that could degrade the membrane.

FAQ

What types of samples can I filter with these syringe filters?

The filters are suitable for aqueous solutions, cell culture media, protein extracts, and most biological samples. They should not be used with strong acids, bases, esters, ethers, or ketones.

How does the PVDF membrane improve protein recovery?

PVDF is known for its low protein binding properties, which means that proteins are less likely to adhere to the filter surface, resulting in higher yields after filtration.

Can I use these filters with a standard 1 mL syringe?

Yes, the 25 mm diameter design is compatible with common 1 mL and 5 mL syringes, providing flexibility for various sample volumes.

What is the recommended storage condition for the filters?

Store the filters in a cool, dry place away from direct sunlight. Keep them in their original packaging until use to maintain membrane integrity.

Is there a warranty or guarantee for these products?

Labfil offers a one‑year warranty against manufacturing defects. If you encounter any issues, contact our support team for a replacement or refund.
