Ahlstrom‘s high purity cellulose extraction thimbles are most commonly used in Soxhlet extraction units for the separation of individual components from a mixture of solids and semisolids by solvent extraction. The use of a Soxhlet extractor provides a safe method of extraction with toxic or…

Quartz thimbles are used for emission testing in high temperature environments. They can also be used for testing acidic gases which are not compatible with micro-glass fiber thimbles. Quartz meets the highest purity requirements due to the lowest possible heavy metal content.

Glass thimbles are used to sample dust particles and aerosols from gaseous streams in the analytical registration of environmental pollution and for Soxhlet extractions requiring solvents too aggressive for the cellulose thimbles.
