Description
Extraction thimbles 250 ml are laboratory consumables designed for extractors with a 250 ml content in solid–liquid extraction workflows. Each thimble has an inner diameter of 33 mm and a height of 205 mm, providing a tall, narrow format that seats in matching 250 ml extractor bodies and keeps the sample bed in the extraction zone during solvent cycling. The defined geometry supports controlled solvent passage through the thimble wall while retaining solids for analytical or preparative work. They are supplied as a pack of 25 pieces from manufacturer Witeg for routine use in chemistry, environmental, food and materials laboratories. Pack net weight is 0,46 kg. These thimbles fit standard setups that call for a 250 ml extractor capacity with a 33 mm inner diameter and 205 mm height, simplifying replacement and method transfer between instruments. They are intended where laboratories need consistent thimble dimensions for sequential or parallel extractions without altering glassware. Choose this size when your protocol specifies a 250 ml extractor and the stated 33 mm inner diameter with 205 mm height.

Questions about Extraction thimbles 250 ml
What is this article?
Extraction thimbles 250 ml is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Extraction thimbles, inside Filtration, in Lab consumables.
An extraction thimble holds a solid inside a Soxhlet or a similar extractor. Cellulose and glass fibre are the two materials. The internal diameter and the height have to match the extractor chamber. A thimble that is too tall blocks the siphon.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
