Description
StockOptions Phosphate buffer kit is a preformulated, sterile filtered set of titrated buffer stocks. The StockOptions buffer stock reagents are supplied as 1.0 M stock solutions in 10 milliliter volumes. Each StockOptions Phosphate buffer reagent is formulated using a mixture of Sodium phosphate monobasic monohydrate and Potassium phosphate dibasic to determine the pH of the reagent. StockOptions Phsophate is comprised of 17 unique reagents covering the pH range of 5.0 to 8.2 in 0.2 pH unit increments.
