The 20 mL sachets are ideal for infrequent calibrations while for heavy-duty applications, you can choose from the popular 230 mL, 1 liter or 1 gallon containers. Now the pH 4 buffers carry lot #, expiry date as well as pH/C chart on every bottle. HI 7004L/C and HI 8004L/C are also supplied with an analysis certificate.
