Buffered Peptone Water 2X (BPW 2X), Sterile, Pre-Enrichment Media

Buffered Peptone Water 2X (double-strength BPW) is a sterile, ready-to-use pre-enrichment medium formulated for microbiological testing workflows requiring a higher concentration to maintain optimal nutrient and buffering capacity after sample dilution. The 2X formulation is commonly used in food safety and environmental testing where equal volumes of sample and media are combined, ensuring proper recovery of stressed or injured microorganisms prior to selective enrichment.

Designed for consistency and convenience, pre-filled BPW 2X formats help standardize workflows, reduce preparation time, and minimize contamination risk during sample processing.

Key Features

• Double-strength (2X) buffered formulation
• Non-selective pre-enrichment medium for microbial recovery
• Maintains buffering capacity after sample addition
• Sterile, ready-to-use formats for streamlined workflows
• Ideal for food, beverage, pharmaceutical, and environmental microbiology labs

Typical Applications

• Pre-enrichment for Salmonella and other target organisms
• Food safety testing protocols requiring double-strength media
• Environmental monitoring and QC microbiology workflows
• Sample dilution and enrichment preparation
