Glass Microfiber Filter Paper - 1410-0240 - Grade 141, 2.40cm 111 This is a very fine

This is a very fine retention filter for gravimetric analysis of very fine particles such as barium and lead sulfates

Quartz thimbles are used for emission testing in high-temperature environments

Grade 237 is also highly suitable for use in Buchner funnels and for dye filtration

as this media will withstand higher temperatures
