Soxhlet Extraction Thimble, Grade 900, Cellulose, 33 x 94 mm, 25 pcs/pack
Article no.: 90033094
Cellulose thimbles by Hahnemühle are the appropriate specimen holders for sophisticated quality control of solid and semi-solid substances. Extraction methods, for instance according to Soxhlet, Randall and Twisselmann, can be carried out with the versatile formats in which grade 900 is available. Their accuracy of fit and mechanical stability offer reliable handling. 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.
