GVS Filter Technology Filter Disc NY Membrane 0.45µm 47mm Pack of 100

Description

Product Overview

The GVS Filter Technology 0.45µm NY Membrane disc is engineered for precision laboratory filtration. Measuring 47 mm in diameter, each disc is fabricated from a high‑performance polyester web that has been coated with a proprietary NY membrane offering a nominal pore size of 0.45 micrometers. The disc is supplied in a convenient pack of 100, allowing laboratories to maintain a ready stock of consistent, high‑quality filters for routine and high‑throughput applications. The membrane is hydrophilic, which means it readily wets with aqueous solutions without the need for additional wetting agents that could interfere with downstream biological assays. Low extractables are a key attribute, ensuring that the filter does not contribute contaminants to the sample, thereby preserving the integrity of HPLC analyses, mass spectrometry, and other sensitive detection methods. The disc’s robust construction provides superior strength, making it easy to handle on automated filtration platforms and reducing the risk of tearing or deformation during use. Package dimensions of 4.72 x 3.78 x 0.91 inches and a lightweight design (1.76 ounces per pack) facilitate storage and handling in busy laboratory environments.

Usage

This filter disc is ideal for a wide range of laboratory and industrial applications. It excels in the clarification of aqueous solutions, such as cell culture media, buffer solutions, and enzyme preparations, where the hydrophilic surface promotes rapid wetting and uniform flow. The disc also performs exceptionally well with organic solvent mixtures, making it suitable for sample preparation steps in high‑performance liquid chromatography (HPLC), gas chromatography (GC), and preparative chromatography workflows. Researchers conducting protein purification, nucleic acid extraction, or small‑molecule analysis will find the low extractable profile essential for maintaining sample purity. The 0.45µm pore size is optimal for removing particulates, microbial contaminants, and precipitates while allowing the passage of dissolved analytes, ensuring that downstream analytical instruments receive clean, particle‑free samples. The disc’s compatibility with standard filtration housings and automated plate‑based systems enables seamless integration into existing laboratory automation pipelines, reducing manual handling time and increasing reproducibility across experiments.
