Grade GF/F Filter for TCLP Test Use, 25 mm circle (100 pcs)
Whatman Grade GF/F binder-free borosilicate glass microfiber fiber is commonly used for biomolecule purification techniques such as DNA purification and protein precipitation as well as landfill leachate toxicity testing.
Stringent particle retention size for biochemical filtering
Applications include:
- DNA purification and binding
- Filtration for protein purification
- Clarifying difficult biochemical solutions and fluids
- Landfill leachate toxicity testing
- Due to its stringent particle retention size specification and pure borosilicate glass composition, the Whatman Grade GF/F glass microfiber filter was chosen by the US Environmental Protection Agency (EPA) for use in developing the Toxicity Characteristic Leaching Procedure (TCLP) 1311. It remains a prominent component for measuring landfill leachate composition
Stringent 0.6-0.8 µm particle retention specification
Manufactured from pure borosilicate glass
| Product specifications |
| Application | Recommended for DNA binding and purification. Very effective in filtering finely precipitated proteins. Can be used in conjunction with GF/D as a prefilter for the successful clarification of extremely ‘difficult’ biochemical solutions and fluids and nucleic acids. Highly suitable for use in applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved. |
