The DiluLok™ Buffered Peptone Water (BPW), 90 mL, from Hardy Diagnostics provides a ready-to-use solution for sample dilution and pre-enrichment of microorganisms prior to microbiological testing. Designed for use in food safety, cosmetics, environmental, and beverage microbiology, these vials simplify laboratory workflows while ensuring accuracy, sterility, and consistency.

Each DiluLok™ bottle is manufactured from clarified, recyclable polypropylene for crystal-clear sample visibility and features a leak-resistant flip-top lid that allows for one-handed operation — saving time during pipetting or serial dilution procedures. The wide 45 mm mouth easily accommodates bulk or particulate samples, and clear 90 mL and 99 mL fill lines ensure precise volume control.

Every lot undergoes strict quality testing for pH, sterility, fill volume, and growth promotion performance, ensuring reliable results batch after batch. DiluLok™ eliminates the need to prepare dilution bottles manually, reducing labor and contamination risks while supporting compliance with FDA, USDA, and ISO microbiological testing standards.
