The Original Weber DB™ Sterilized Pre-filled Dilution Bottles featuring a tamper evident sterility strip that is integrated as part of the cap. It is much easier to open and use. Never hassle with shrink bands again! Every bottle is pre-filled to either 99 or 90 mL ±2 mL, buffered to pH 7.2 ±0.2, has an overall capacity of 150 mL, and is recy­clable. Two formulations are available:

Butterfield’s Buffer for foods and dairy products (APHA, FDA, AOAC or USP methods). Contains purified water, monobasic potassium phosphate and sodium hydroxide for pH adjust­ment.

Phosphate Buffer for water and wastewater (APHA or EPA methods). Contains magnesium chloride, monobasic potassium phosphate and sodium hydroxide for pH adjustment.

Huge freight savings and faster delivery throughout the United States

Dilution bottles ship out of our Nevada warehouse for delivery to Western states and out of our Missouri warehouse for selected Southern and Midwestern states. Customers in these areas will realize significant freight savings plus shipments will be received sooner.

Eastern states will continue to receive fast and economical service from our facility in New Jersey.

Natural is the new green.

We’ve switched to a natural polyethylene cap for our Original Weber DB™ Dilution Bottles. This eliminates the need for the dyes we used to use.

Our packaging already was designed to have a 60% smaller footprint and three times less corrugated waste than the competition. And as always our bottle and cap are 100% recyclable. Taken all together we think it is a good move towards our Sustainability Vision.

The bottles are still color-coded! The lettering on the side of each bottle is now color-coded for easy identification.
