Description
Extraction thimble MN 645, 15x100 mm is a laboratory extraction thimble supplied in the MN 645 format with an inner diameter of 15 mm and a height of 100 mm. Dimensions are specified as inner diameter × height, giving a defined cylindrical chamber for solid–liquid extraction work. Each pack contains 25 pieces, supporting routine sample preparation and continuous extraction setups in analytical laboratories. The product type MN 645 identifies this standardised sleeve geometry for consistent loading of solid matrices during solvent extraction. These extraction thimbles from manufacturer Macherey-Nagel are intended for general laboratory use where reproducible thimble dimensions are required. The non-sterile articles suit chemical, environmental and quality-control workflows that rely on fixed-format extraction sleeves. Pack net weight is 0,11 kg. Originating from Germany, the MN 645 series provides a practical pack size for day-to-day laboratory consumption. The clear dimensional specification (15 mm × 100 mm) helps match apparatus requirements and maintain process consistency across repeated extractions. Use these thimbles wherever a compact MN 645 extraction sleeve of this height and diameter is specified.

Questions about Extraction thimbles MN 645, 15x100 mm
What is this article?
Extraction thimbles MN 645, 15x100 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.
