Hardened Quantitative Filter Paper - 0750-0550 - Grade 75, 5.50cm 5.50cm This is an extremely fine

This is an extremely fine retention filter for critical gravimetric analysis and metal determination of very fine particles such as barium and lead sulfates

Grade 222 has a smooth and uniform texture which assures continuous contract of buffer from the chamber through the gel and transfer membrane to the opposite pole or weight

enabling more precipitate to be held without clogging the filter

Hardened Quantitative Filter Paper - 0750-0550 - Grade 75, 5.50cm 5.50cm This is an extremely fineAhlstrom Munksj 75 2. 0 m, Medium Speed This grade has medium flow rate and good particle retention and is most commonly used for applications requiring high chemical resistance to strong acid and alkali. Grade 75 is often used for filtering trace elements, collecting hydroxides after precipitation by strong alkalis and in the analysis of metals in acid and alkali solutions.
