Beschreibung
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.
