Nalgene™ analytical filter funnels are sterile disposable funnels intended for microbiological quality-control testing and analysis of water, foods and beverages, raw materials and finished products. The cellulose nitrate membrane measures 47 mm in diameter and presents a gray surface with a black grid to aid colony counting and visual inspection during analytical filtration. A 250 mL working volume supports typical sample loads, and the funnels are designed for use with filter manifolds and filtering flasks in routine laboratory setups. They meet the requirements of APHA Standard Methods and EPA requirements for water quality work, which suits regulated environmental and product-testing workflows. Each case contains 50 pieces from manufacturer Thermo Scientific - Laboratory Plastics, giving an economical single-use format that reduces washing effort and cross-contamination risk between samples. These analytical funnels help quality-control laboratories maintain consistent disposable filtration hardware for microbial enumeration, water testing and related checks on incoming materials and finished goods.
This article belongs on Bottle-top & vacuum filtration units, in Filtration.

Questions about Nalgene™ Single Use Analytical Filter Funnels
What is this article?
Nalgene™ Single Use Analytical Filter Funnels 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.
