Weber DB™ Sterilized Pre-filled Dilution Bottles and Tubes



Sterilized Pre-Filled Dilution Bottles:

Weber pre-filled dilution bottles are used to dilute a liquid or particulate sample for the purpose of microbial enumeration on Petri plates.  Our sterile buffers are manufactured per Standard Methods for the Examination of Dairy Products and Standard Methods for the Examination of Water and Wastewater.  This provides an industry standard that is readily accepted by applicable regulatory agencies.

Each bottle is pre-filled to either 99 or 90 mL, buffered to pH 7.2 +0.2, has an overall capacity of 150 mL and is 100% recyclable.  Two formulations are available:

Butterfield’s Buffer is frequently used in the food and dairy industries (APHA, FDA, AOAC or USP methods). Contains purified water, monobasic potassium phosphate and sodium hydroxide for pH adjust­ment.

Phosphate Buffer is the same as Butterfield’s Buffer but also contains magnesium.  This is commonly used in the water and wastewater industries (APHA or EPA methods). Contains magnesium chloride, monobasic potassium phosphate and sodium hydroxide for pH adjustment.

Applications for Butterfield and Phosphate Buffers:
  • Foods & Beverages
  • Water and Wastewater
  • Cosmetics
  • Pharmaceuticals
  • Environmental Samples


Sterilized Pre-Filled 9 mL Dilution Tubes:

We also manufacture sterile pre-filled dilution Tubes available in Butterfield’s Buffer.  These tubes are pre-filled to 9 mL and have an overall capacity of 13 mL.  This provides an advantage in working with smaller volumes in a smaller footprint.
