Description
Filter thimble MN 649 R is a micro glass fibre filter thimble for laboratory filtration and extraction-related sample handling. It measures 79 mm inner diameter by 155 mm height, stated as format 79 × 155 mm (inner diameter × height). The shorter cylindrical profile suits apparatus and workflows that need a compact glass-fibre sleeve for retaining solids while liquid or solvent passes through. Applications include sample clean-up, particulate retention, and extraction steps in chemical, environmental, and food laboratories where a glass-fibre matrix is required. Packs of 25 pieces support routine bench use. The MN 649 R micro glass fibre design from manufacturer Macherey-Nagel offers the thermal and chemical stability typical of glass-fibre thimble media. Matching glassware or holders that accept a 79 mm inner diameter and 155 mm height allow straightforward installation. These non-sterile laboratory consumables are intended for preparative and analytical sample work rather than sterile processing. Consistent pack geometry helps maintain reproducible loading and flow behaviour from run to run.

Questions about Extraction thimbles MN 649 R,glass fiber, 79x155
What is this article?
Extraction thimbles MN 649 R,glass fiber, 79x155 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.
