pH Buffers and Solutions From Sensorex

Sensorex - pH Buffers and Solutions

Sensorex supplies pH buffers as pre-mixed, ready-to-use, color-coded liquids -- red (pH4.01), yellow (pH7.00) and blue (pH 10.00). All buffers are guaranteed accurate to within +/- 0.01 pH units @ 25 deg C. Available sizes include pints (473mL), quarts (946mL) and gallons (3.786L). Buffer labels include pH vs. temperature information for precise calibration. Custom buffers are also available on an OEM basis. Please contact Sensorex regarding your requirements.

Electrode storage solution is available in pint and gallon sizes. This is the same solution that is shipped with all pH electrodes and ensures electrodes are ready for immediate use. Storage solution is recommended for long-term electrode storage since it is not color-coded and will not impart any color to the electrode's reference junction.

pH Buffers

Sensorex buffers are accurate to within +/-0.01 pH units @ 25C and remain stable over long periods of time.

Standard packaging is shown below.  Buffers are available in pint (473 ml) or gallon (3.784 Liter) sizes.

As with all buffers, these solutions are temperature sensitive. For accurate calibration, heat or cool your buffer solution to 25 degrees C before using. If this is not convenient, compensate for For the thermal errors associated with these buffers.
