Johnson Test Papers offers an extensive range of extraction thimbles available in both cellulose and glass fibre and in a variety of dimensions and wall thicknesses. We also offer cellulose extraction thimbles specifically sized for automated extraction equipment.
Johnson Test Papers' cellulose extraction thimbles are widely used in Soxhlet extraction equipment, a technique for the analysis of fats or pesticides in food and soil materials. Cellulose extraction thimbles are also used for crude oil sampling to determine amounts of oil in oil - water slurries.
Glass micro fibre extraction thimbles are used for high-temperature applications such as analysis of smoke stack gases for environmental monitoring or when solvents are incompatible with cellulose extraction thimbles.
