Preferred by chemists for its predictable behavior in reaction systems, the Filter Circles, Quantitative, Grade 54, Ø 55 Mm offer rapid filtration times due to their high filtration speed of 39 seconds. Manufactured by Whatman, these filter circles boast a basis weight of 92 grams per square meter and a typical thickness of 185 micrometers. They are designed to handle coarse and gelatinous precipitates, making them ideal for vacuum-assisted fast filtration processes. With an ash content of just 0.015%, these filter circles provide excellent particle retention, ensuring that particles larger than 20 to 25 micrometers are captured during the filtration process.
