The DiluLok™ Buffered Peptone Water (BPW), 99 mL, from Hardy Diagnostics is a ready-to-use, sterile dilution bottle designed for microbiological testing and pre-enrichment of injured or stressed Salmonella species from food, environmental, and cosmetic samples.

Formulated with casein peptone as an enrichment base, this medium provides optimal recovery of sub-lethally injured microorganisms prior to selective enrichment and plating. Each DiluLok™ vial is precision-filled and QC tested for pH, sterility, fill volume, and microbial growth promotion, ensuring dependable results in compliance with FDA, BAM, ISO, and USDA microbiological testing standards.

The flip-top, leak-resistant lid allows for smooth one-handed operation, minimizing cross-contamination and improving workflow efficiency. Its wide 45 mm mouth accommodates large or complex sample matrices — ideal for food, beverage, and environmental labs handling diverse material types.

Each bottle features 90 mL and 99 mL fill lines, tamper-evident shrink seals, and a clarified polypropylene body that allows clear sample viewing and easy labeling. DiluLok™ eliminates the need for in-house preparation, saving valuable time and reducing contamination risks.
