Huge Freight Savings and Faster Delivery to the Western United States Weber DB™ is now stocked in two locations.

Plus, Weber DB™ shipments will be received between two to five days sooner. The rest of the country will continue to receive fast and economical service from our main distribution facility located in New Jersey NOTE: NOW AVAILABLE 72 PER CASE!

pH measurement is now simplified

The Weber DB™ has been improved to allow fast and accurate pH confirmatory results using standard pH measurement technique. This is a real benefit - there is no longer any need to use low ionic strength buffers or additives. This improvement was made possible due to innovative technological advances in our manufacturing process.

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.
