Hardy Diagnostics Butterfield’s Phosphate Buffer (pH 7.2, 9ml) is a sterile, ready-to-use diluent designed for preparing sample dilutions in plate count and microbiological testing procedures. It is widely used across food, beverage, and environmental laboratories, as well as in Cannabis QA and industrial hygiene applications.

Formulated according to APHA and FDA Bacteriological Analytical Manual (BAM) specifications, this buffer provides a consistent pH environment to maintain microbial cell viability during sample handling and transport.

Each tube is made from optically clear glass for distortion-free visibility and features a leak-proof cap for secure transport. The flat-bottom design ensures bench stability, minimizing the risk of tipping during use.

Features and Benefits:
• Pre-measured 9ml volume for accurate dilutions
• pH 7.2 ± 0.1 — ideal for microbial recovery and enumeration
• Flat-bottom tubes ensure stability on benchtops
• Leak-proof caps for secure transport and handling
• Optically clear glass provides distortion-free observation
• Meets APHA and BAM standards for microbiological testing
• Ready-to-use format saves preparation time and reduces contamination risk
