Microbial Limits Testing (USP): Used as a diluent/rinse in USP <61>/<62> microbial enumeration methods for nonsterile products, supporting recovery of organisms such as Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.

Membrane Filtration Rinsing: Serves as a sterile rinse to wash filters during bioburden and water testing, minimizing cell stress and carryover to improve recovery of Escherichia coli and Pseudomonas aeruginosa.

Sample Preparation and Dilution: Functions as an isotonic, low-nutrient diluent for homogenization and serial dilutions prior to plate counts of product, environmental, and water samples.

Environmental Monitoring: Employed as a rinse/extraction medium for swabs and contact plates from surfaces and equipment to enumerate organisms like Staphylococcus aureus and Bacillus subtilis.

Bioburden Testing: Used to recover and quantify microbial load from raw materials, in-process samples, and finished goods without promoting overgrowth.

Pharmaceutical and Cosmetic Testing: Applied as a neutral diluent for product testing workflows to assess absence/presence of objectionable organisms including Escherichia coli and Pseudomonas aeruginosa.

Food and Beverage Microbiology: Utilized as a nonselective diluent for aerobic plate counts and sample rinses to maintain viability of stressed cells.

Equipment and Container Rinses: Used as a sterile rinse fluid to collect residues and microorganisms from process equipment and packaging for downstream culture-based enumeration.
