Phosphate Buffered Dilution Water w/MgCl2 99mL Bottle, 1/Pk

Phosphate Buffered Dilution Water, commonly known as Butterfield's Buffer, is the standard sterile diluent recommended by the FDA, APHA, and AOAC for the preparation of food, dairy, and water samples. This bottle contains Magnesium Chloride MgCl2, which improves the recovery of metabolically injured or "stressed" organisms that might otherwise die in distilled water or saline.

The Versatility of the 99mL Fill:

The 99mL volume is specifically calibrated to simplify calculation and dilution protocols in two common scenarios:

1. The 1:10 Dilution (Initial Suspension):

   • Technicians often weigh out 11g of a solid food sample (or pipette 11mL of liquid).

   • Adding this to the 99mL bottle results in a total volume of 110mL.

2. The 1:100 Dilution:

   • Adding 1mL of a sample (or 1mL of a previous dilution) to the 99mL bottle results in a total volume of 100mL.

• Regulatory Standard: Compliant with FDA Bacteriological Analytical Manual (BAM) and APHA Standard Methods.

• Magnesium Enriched: Stabilizes cellular structures to maximize recovery of stressed bacteria.

• Dual Utility: Perfect for making 1:10 suspensions (with 11g sample) or 1:100 dilutions (with 1mL sample).

• Ready-to-Use: Sterile liquid eliminates media preparation time.

• Format: Single 99mL screw-cap bottle.
