Johnson Analytica offers an extensive range of extraction thimbles available in both cellulose and glass fibre and in a variety of dimensions. We also offer cellulose extraction thimbles specifically sized for automated extraction equipment.

Johnson Analytica 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.
