No more ordering multiple small packages of NIST-traceable pH buffers to provide the volume to meet your testing needs. Ricca Chemical Co., of Arlington, Texas, has added several new packaging options. Now all pH values from 1 to 11 are available in larger sizes, including the money saving 10 and 20 L “cubes” (bag in a box) or carboys. The company has the buffer you need in stock, no matter what range you are testing in. These new sizes are manufactured to the tightest tolerance (+/-0.01 pH units).
