Description
Nalgene™ Analytical Filter Funnels are sterile, single-use filter funnels intended for microbiological quality-control procedures and the analysis of water, food and beverages, raw materials and end products. Each unit combines a cellulose nitrate membrane (CN, MCE) of 0,45 µm pore size and 47 mm diameter with a 250 mL funnel volume, and the white membrane is printed with a black grid to aid colony counting and enumeration. The design complies with US APHA Standard Methods and US EPA requirements for water-quality testing and carries ISO 7704 certification, making the funnels well suited to regulated laboratory environments. Suitable for use with filter manifolds and filter flasks, these economical disposable units streamline routine filtration workflows while reducing cross-contamination risk. Available as a case of 50 pieces from manufacturer Thermo Scientific - Laboratory Plastics, they support consistent sample handling in analytical and QC laboratories without cleaning or re-sterilisation between runs, helping maintain throughput and data integrity across diverse sample matrices.
