37mm Cellulose Fiber Filter Media, 100/pk SKU: TE-241-37

The TE-241-37 is a 37mm cellulose fiber filter designed for gravimetric air sampling applications where high particle retention and accurate weight measurements are essential. These qualitative cellulose filter papers perform separation by entrapping particulate within the random matrix of cellulose fibers within the depth of the media.

Technical Operation

Filtration through cellulosic fiber-based media depends on the pore sizes in the fibrous mat, with manipulation of pore size serving as an important tool to improve filtration efficiency through diffusion, interception, and sieving mechanisms. A typical filter will have a rough side and a shiny side, optimizing particle capture during air sampling operations.

Key Specifications

• Diameter: 37mm
• Type: Ashless cellulose fiber
• Pack quantity: 100 filters
• Construction: Pure cellulose without support pad

Compatibility

Compatible with standard 37mm filter cassettes and sampling equipment commonly used in environmental monitoring and industrial hygiene applications. Suitable for personal air sampling pumps and area sampling devices requiring 37mm filter media.

Applications

Often specified in air monitoring applications where the entrapment of fine particulate is not required, making them ideal for initial-stage filtration processes. These procedures include standard environmental test procedures such as soil sample analysis and the collection of trace elements and radionuclides in air samples. Very commonly used as the first media in a multi-stage filtration process and ideally suited for use in organic extractions and biological fluid separation processes.

Maintenance Notes

Store filters in a clean, dry environment to maintain integrity. Handle with clean forceps to prevent contamination. Pre-condition filters according to sampling protocol requirements for gravimetric analysis to ensure accurate weight measurements.
