These are pH calibration and buffer solutions to allow you to adjust your testing system to measure your samples' unknown pH more precisely. Always choose a pH 7 buffer plus at least one other pH value close to your expected measurement range. Calibration should be performed before each reading or each set of readings. For best accuracy perform standardizations with fresh buffer solutions. Never pour used buffer back into the bottle. Use buffers directly above and below the expeted value of your sample and match the temperature of the buffer to the temperature of the samples.
