Johnson Test Papers offers an extensive range of extraction thimbles available in both cellulose and glassfiber and in a variety of dimensions and wall thicknesses. We also offer cellulose 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 thimbles are also used for crude oil sampling to determine amounts of oil in oil water slurries. Glass microfiber extraction thimbles are used for high-temperature applications such as analysis of smoke stack gases for environmental monitoring or when solvents incompatible with cellulose thimbles are needed.

Extraction thimbles are used for holding solid materials from which certain substances are to be eluted/extracted with a suitable solvent. They may also be used in the field for gas and waste air analysis for collecting solid particles (dust). Our extraction thimbles are made from pure cellulose and suitable for Soxhlettype or similar devices.
