Syringe Filters Hydrophilic PTFE 25 mm 0.45 um Non Sterile 100/pk

Description

Product Overview

The SERHICS LAB Hydrophilic PTFE Syringe Filter is engineered for precision laboratory filtration, delivering consistent performance across a wide range of applications. Constructed with a high‑quality hydrophilic PTFE membrane, the filter provides a 0.45 µm pore size that effectively captures particulate matter while allowing essential fluids to pass through with minimal resistance. The filter measures 25 mm in diameter, a standard size that integrates smoothly with most syringe systems, and is supplied in convenient packs of 100, ensuring you have ample supply for routine and high‑throughput workflows.

Key specifications include a female Luer inlet and a male slip Luer outlet, facilitating quick and secure connections to syringes and other laboratory equipment. The non‑sterile design is suitable for a variety of sample types, provided proper pre‑wetting procedures are followed to avoid back‑pressure issues. With a robust construction that resists chemical degradation, this filter is ideal for filtering culture media, liquid cultures, and grain spawn jars, making it a versatile tool for microbiology, mycology, and biotechnology labs.

Usage

Designed for laboratory environments, the filter excels in scenarios where small‑volume samples require thorough purification. Researchers commonly employ the filter when preparing culture media for bacterial or fungal growth, ensuring that contaminants are removed without compromising the nutritional composition of the media. It is also frequently used in liquid culture preparations, where clarity and sterility are paramount for downstream processes such as inoculation or analytical testing.

In addition to microbiological applications, the filter serves well in analytical chemistry workflows, including sample preparation for chromatography or spectroscopic analysis. Its hydrophilic PTFE membrane is compatible with a broad spectrum of aqueous solutions, provided the samples are pre‑wetted to reduce surface tension and prevent excessive back‑pressure. The filter’s Luer connections enable rapid attachment to standard syringes, allowing users to integrate it seamlessly into existing protocols without the need for additional adapters or equipment.

When handling grain spawn jars, the filter helps maintain a sterile environment by preventing the ingress of airborne spores while allowing gas exchange, supporting healthy mycelial development. This dual functionality makes the filter an essential component for both research and production settings where contamination control is critical.

FAQ

What types of samples can I filter with this syringe filter?

The filter is suitable for aqueous samples such as culture media, liquid cultures, and grain spawn jars. It can also be used for many biochemical solutions, provided the sample is pre‑wetted to avoid high back‑pressure.

Do I need to sterilize the filter before use?

This product is supplied non‑sterile. If sterility is required for your application, you should sterilize the filter using an appropriate method, such as autoclaving, before use.

Can I use this filter with viscous solutions?

Viscous solutions can be filtered, but you may experience increased back‑pressure. Pre‑wetting the membrane and using a slower flow rate can help mitigate this issue.

What is the recommended pre‑wetting procedure?

To pre‑wet the filter, pass a small volume (approximately 0.5 mL) of the same buffer or solvent that will be used for the sample through the filter. This prepares the membrane and reduces surface tension, ensuring smoother filtration.

How do I dispose of used filters safely?

After use, place the filter in a designated biohazard container if it has contacted potentially hazardous materials. Follow your institution’s waste disposal guidelines for laboratory consumables.
