Calibration should be performed before each reading or each set of readings. pH buffers allow you to adjust your testing system to measure your samples' unknown pH more precisely.Perform standardizations with fresh buffer solutions. Never pour used buffer back into the bottle; always discard after using.. Use buffers that frame the pH range of the samples you are testing (i.e. directly above and below the expected value of your sample.) Match the temperature of the buffer to the temperature of

The pH of this buffer is 7.4 (0.1M); the osmolarity is 440 mosmols, so this buffer is hypertonic to most body fluids. Millonig recommended to use this buffer for the fixation of very hydrated tissues with osmium tetroxide. For marine organisms, a higher concentration of sodium chloride (3%) is recommended. We supply it in a double strength (0.2M), pH 7.4. Dilution is needed before use.0.2m. 1L. Sold in each.
