Nalgene™ reusable bottle top filters made of polysulfone combine the convenience of a bottle-top filtration setup with the economy of a reusable unit. Designed for secure screw mounting on glass media bottles, they suit necks with a 45 mm thread (GL 45) and are also described for use with 33 mm or 45 mm bottle necks. The upper reservoir holds 500 mL (nominal volume 0,5 l), supporting routine media and buffer preparation in the laboratory. Constructed from polysulfone, the filter is autoclavable, enabling repeated sterilisation cycles between uses. Each unit is supplied as a single piece, with a gross weight of 0,363 kg, making it practical for benchtop filtration workflows where disposable tops would generate unnecessary plastic waste. These bottle-top filters from manufacturer Thermo Scientific - Laboratory Plastics fit standard laboratory media bottles and are intended for filter-holder and sterile-filtration applications. The reusable design helps laboratories maintain consistent filtration practice while reducing consumable turnover. Suitable for general laboratory filtration tasks that require a durable, screw-on bottle-top interface and reliable chemical-resistant polymer construction.

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 Bottle-top & vacuum filtration units, inside Filtration, in Verbruiksartikelen.
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.
