Whatman - Cellulose extraction thimbles are produced from high quality alpha cellulose cotton linter and have excellent mechanical strength and retention. Standard single thickness thimbles have a wall thickness of approximately 1mm (10 ?M nominal particle retention). These thimbles are used in Soxhlet extraction units providing a safe, convenient and efficient method of solvent extraction of solids and semi-solids. Soxhlet extraction is a widely used technique for the analysis of fats or pesticides in foods and soil materials and many other procedures that involve a solid-liquid extraction.
