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 semi-solids by solvent extraction. The use of a Soxhlet extractor provides a safe method of extraction with toxic or other noxious solvents. Ahlstrom extraction thimbles are recommended for the estimation of fats in food, analysis of lacquer and binder in paints, vitamin A and carotene extractions, and extraction of organic compounds from reaction mixtures. Thimble walls are approximately 1.5mm thick and have been found to perform satisfactorily in applications requiring either single or double wall thickness.
