• Seamless, high-purity filters for extraction and air monitoring

• Collection efficiency is 99.95%

Thimble filters are used in soxhlet apparatus for dust sampling and for extracting soluble components using organic solvents.
Glass fiber thimbles of borosilicate glass are acid washed for minimum trace metal content. They are acid resistant (except hydrofluoric) and ideal for high temperature extractions up to 932°F (500°C). Thickness is 1.6 mm.
