Description
Extraction thimble MN 649 is a micro glass fibre extraction sleeve for demanding solid–liquid extraction work in the laboratory. With an inner diameter of 33 mm and a height of 205 mm, it offers an extended cylindrical chamber for larger sample amounts or longer extraction beds in Soxhlet-style and related apparatus. The micro glass fibre construction provides solvent flow through the packed sample while resisting the thermal and chemical conditions of common extraction solvents. Packs contain 25 pieces and come from manufacturer Macherey-Nagel, making the MN 649 33×205 mm format practical for routine and series work in environmental analysis, food and feed testing, natural-product chemistry, and industrial quality control. Defined geometry (inner diameter × height) supports reproducible packing density and solvent contact, which are critical for consistent recoveries and method comparability. These thimbles are intended for professional laboratory applications that call for a tall glass-fibre extraction sleeve of 33×205 mm.
This article is part of Extraction thimbles, in Filtration.

Questions about Extraction thimbles MN 649, glass fiber, 33x205 mm
What is this article?
Extraction thimbles MN 649, glass fiber, 33x205 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.
