Description
Extraction thimble MN 645, 55x275 mm is a laboratory extraction sleeve intended for solid–liquid extraction procedures. The MN 645 format defines an inner diameter of 55 mm and a height of 275 mm, combining a moderate bore with substantial vertical capacity for sample loading. Supplied in packs of 25 pieces, the thimbles suit regular laboratory consumption and multi-user environments. These dimensions (inner diameter × height) are chosen to maintain mechanical stability and a reproducible packing volume while solvent percolates through the retained solids. Applications include classical Soxhlet-type extractions and related continuous or semi-continuous methods used in food analysis, environmental monitoring, pharmaceutical sample preparation and natural-product research. Extraction thimbles of this type from manufacturer Macherey-Nagel belong to the MN 645 product line and integrate with standard extraction glassware. Uniform geometry supports comparable extraction conditions between batches and operators. The pack net weight is 1,90 kg, practical for central stores and bench-side inventory. Choose the 55 mm × 275 mm MN 645 thimble when a defined intermediate format is required for quantitative recovery of extractable constituents under controlled laboratory extraction conditions.

Questions about Extraction thimbles MN 645, 55x275 mm
What is this article?
Extraction thimbles MN 645, 55x275 mm is the article on this page. Luminix Health distributes Macherey-Nagel 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.
