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 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

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
