Ahlstrom’s high purity cellulose extraction thimbles are 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 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
- extraction of organic compounds from reaction mixtures.
Cellulose extraction thimbles walls are approximately 1.5 mm thick and have been found to perform satisfactorily in applications requiring either a single or double wall thickness.
