I.W. Tremont offers a wide selection of high quality extraction thimbles available in a variety of dimensions to fit most Soxhlet extraction units. Our extraction thimbles are manufactured in high purity cellulose fibers or high purity glass binderless microfiber. They also feature a consistent wall thickness.
Custom manufacturing is available for tubes, sleeves and additional sizes.
Common Thimble Applications
- Soxhlet extraction
- Air and waste gas analysis
- Collection of solid particles such as dust
- Smoke stack gas monitoring
- Analysis of pesticide residues
- Oil/fat content of solid foods
- Oil & grease analysis of solid wastes
- Elution for biochemical analysis
Material Specifications
Extraction thimble measurements as expressed by our company are standard measurements of Inner Diameter (I.D.) x Height.
Outer diameter measurements can be estimated by adding twice the wall thickness plus inner diameter.
Upon ordering, please mention instances requiring precise outer diameter measurements for use in automated extraction apparatus such as; Foss,Velpe, Büchi, Dionex and Gerhardt.*
