Extraction thimbles are often used when you need multiple extraction cycles to dissolve the desired compound in the lab. Extraction units such as the Soxhlet extractors or automized extractors, equipped with extraction thimbles, can save the time of handling and make the extraction complete. You can find two kinds of our products: cellulose extraction thimbles and glass fiber extraction thimbles.
Hawch cellulose extraction thimbles, made of high-quality alpha cellulose cotton linter always play a good role in automated Soxhlet extractor systems. These cellulose extraction thimbles have perfect mechanical strength and retention, as well as their consistent high porosity ensures fast flow through. Suitable for temperatures up to 120°C (248°F), they can be used in a field of solid-liquid extraction studies, such as food lipid and pesticide analyses in food and soil samples.
Totally free of binders or additives, Hawach glass fiber extraction thimbles are made of Borosilicate glass fibers. Suited for temperatures up to 500°C (932°F), they are often used when solvents are not compatible with cellulose thimbles. Glass fiber extraction thimbles are often suitable in the field of monitoring smokestack gas, analyzing pesticide residues and determining oil/fat content of foods.
