Filtry z włókna szklanego GF/F, bez lepiszcza

Filtry GF/F produkowane są z czystego szkła borokrzemowego. GF/F oferuje retencję bardzo drobnych cząstek przy dobrym przepływie i obciążalności.
Whatman Grade GF/F filter from GE Healthcare’s Life Sciences business is manufactured from pure borosilicate glass. GF/F offers very fine particle retention and good loading capacity and flow rate.

• 0.7 µm nominal particle retention
• Served as the basis filter for EPA standard for the toxicity characteristic leaching procedure

GE’s Whatman brand glass microfiber filters provide reliable results in a variety of critical filtration procedures. Find the right particle retention rating and thickness for your analysis in the Whatman binder-free range.

Glass fiber TCLP test filters
When the U.S. Environmental Protection Agency (EPA) Toxicity Characteristic Leaching Procedure 1311 was developed, it recommended using the Whatman Grade GF/F filter. Grade GF/F remains a popular and prominent component for measuring landfill leachate composition with a TCLP test. Other applications include:

• DNA binding and purification
• Filtering finely precipitated proteins
• Filtering biochemical solutions, fluids, and nucleic acids
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.
