Features
•Once buffer are used for calibration, they are assumed contaminated and should not be used again. Reusing buffers can lead to slow pH electrode response or the inability to calibrate. The cause of calibration failure is difficult to determine if the pH buffers have already been used. Used beffer solutions can be kept for rinsing the calibration container and the electrode between calibration points.
•Expired buffer solutions should not be used and buffer bottles should not be left open. Carbon dioxide in the air can change the pH of basic buffer solutions, so basic buffer bottles should only briefly be opened. Use opened containers of buffer as soon as possible
•Expiration dates are printed on the label of the buffer bottle, and according to the LOT code visit ohaus.com/Lot-certificates
