Soxhlet Extraction Thimble, Grade CFV, Glass Fiber (100% Borosilicate), 19 x 90 mm, 25 pcs/pack
Article no.: CFV19090
The filtration and determination of dusts and aerosols from gas and air flows can best be performed with glass fiber thimbles. They offer a high degree of air permeability and a good stability at temperatures of up to 500°C. Modern, automatic extractors with high sample throughput and fast process flow can also be equipped with the Hahnemühle thimbles to ensure an excellent reproducibility of analysis results.
The ever increasing demands on analysis sensitivity are met by the thimbles that exhibit a minimal content of extractable substances. Only specially selected crude fibers that have been tested for extractable substances are used in production. Stringent criteria for approval by quality control guarantee constant values as far as dimensions, wall thickness and air permeability are concerned.
*Thimble sizes should be selected carefully to fit extractors correctly.
