Thimbles are cylindrical, porous containers used to hold solid samples during Soxhlet extraction and similar solvent-extraction processes. Available as cellulose thimbles or glass fiber thimbles, they retain solid particles while allowing solvent to pass through repeatedly, supporting complete and efficient extraction of oils, fats, and other compounds. Cellulose thimbles suit general extraction work, while glass fiber thimbles offer better chemical and temperature resistance for more demanding applications. Laboratories use extraction thimbles in food testing, environmental analysis, and pharmaceutical research to achieve consistent sample containment without contamination or sample loss. Axibio supplies extraction thimbles designed to support accurate, repeatable results in analytical and quality-control laboratories.
