Description
Nalgene™ Reusable Bottle Top Filter made of polysulfone combines the practical handling of a bottle-top filter with the economy of a reusable housing. The upper chamber offers 500 mL working volume, corresponding to a nominal volume of 0,5 l, for filtration of culture media, buffers and clear laboratory solutions directly into receiving bottles. It is designed for secure screw mounting on glass media bottles and, for this article, fits a 33 mm bottle thread. Across the range, 33 or 45 mm necks are addressed; this configuration is specified for the 33 mm thread size. Polysulfone construction is autoclavable, allowing thermal sterilisation between uses when laboratory procedures permit reuse. Each filter is supplied as one piece for media kitchens, cell-culture support labs and microbiology suites. This Nalgene reusable bottle-top filter from manufacturer Thermo Scientific - Laboratory Plastics supports laboratories that standardise on glass media bottles and wish to limit fully disposable assemblies. Gross weight is 0,363 kg and packaging volume is 0,004 m³. Mount only on matching glass bottles, check thread and sealing surfaces before vacuum is applied, and follow your validated autoclave cycle whenever the unit is prepared for sterile media or buffer filtration work.

Questions about Nalgene™ Reusable Bottle Top Filters
What is this article?
Nalgene™ Reusable Bottle Top Filters is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Unités de filtration sur flacon & sous vide, inside Filtration, in Consommables.
A bottle-top filter or a vacuum filtration unit sits on a bottle and pulls a liquid through a membrane under vacuum. Pore size and membrane are the same choice as a syringe filter, at a larger area. A sterile unit is a stated claim. The bottle neck has to match.
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.
