Sterile Syringe Filters KS‑Tek PVDF 25mm 0.22 µm 10‑Pack

Description

Product Overview

The KS‑Tek sterile syringe filter is engineered for demanding laboratory environments where precision and reliability are paramount. Featuring a high‑performance polyvinylidene fluoride (PVDF) membrane, the filter delivers a nominal pore size of 0.22 µm, effectively removing particulates, microbes, and endotoxins from a wide range of liquid samples. The 25 mm housing conforms to standard syringe dimensions, allowing seamless integration with both manual and automated syringe systems. Each filter is individually packed, guaranteeing sterility until the moment of use and minimizing the risk of cross‑contamination.

Designed with a female Luer inlet and a male slip‑Luer outlet, the filter provides a secure, leak‑free connection that supports sample volumes up to 100 ml. The low hold‑up volume of the PVDF membrane ensures maximum sample recovery, a critical factor when working with precious or limited‑quantity specimens. The robust construction resists chemical degradation from a broad spectrum of solvents, making the filter suitable for applications ranging from pharmaceutical analysis to environmental testing.

Usage

These syringe filters are ideal for a variety of laboratory workflows, including sample preparation for high‑performance liquid chromatography (HPLC), gas chromatography (GC), and mass spectrometry (MS). Researchers in biochemistry, microbiology, and environmental science rely on the consistent performance of the PVDF membrane to protect sensitive analytical instruments from clogging and contamination. The filter’s compatibility with a wide range of solvents—such as water, methanol, acetonitrile, and dimethyl sulfoxide—enables its use in diverse protocols, from protein precipitation to pesticide residue analysis.

Because the filters are supplied in packs of ten, laboratories can maintain a ready stock of sterile, ready‑to‑use units, reducing downtime between experiments. The individual packaging also simplifies inventory management and ensures that each filter remains sterile until the point of application. Whether you are processing clinical samples, conducting research on environmental water quality, or preparing standards for calibration, the KS‑Tek syringe filter provides a dependable barrier against contaminants.

FAQ

What types of solvents are compatible with the PVDF membrane?

The PVDF membrane is chemically resistant to a broad range of solvents, including water, methanol, acetonitrile, isopropanol, and dimethyl sulfoxide. It is also compatible with buffered solutions and weak acids, making it suitable for most analytical and preparative applications.

Can the filter be used for both aqueous and organic samples?

Yes. The filter’s PVDF membrane is designed to handle both aqueous and organic phases without compromising filtration efficiency. This versatility allows users to employ the same filter for diverse sample types, reducing the need for multiple filter inventories.

What is the maximum sample volume that can be filtered?

The filter is rated for sample volumes up to 100 ml per filtration event. For larger volumes, multiple filtration steps or larger‑capacity filters should be considered to maintain optimal performance.

How does the low hold‑up volume benefit my experiments?

Low hold‑up volume minimizes the amount of sample retained within the filter housing and membrane, which is especially important when working with scarce or expensive reagents. This feature ensures that nearly the entire sample passes through the filter, improving yield and analytical accuracy.

Is there a warranty or guarantee for these filters?

KS‑Tek offers a standard one‑year warranty covering manufacturing defects. Should any issues arise, our customer service team will work with you to provide replacements or technical assistance promptly.
