pH Buffers and Solutions

pH Buffers and Solutions From Sensorex

Sensorex supplies pH buffers as pre-mixed ready-to-use color coded liquids--blue for 10pH, red for 4.01pH, and yellow for 7pH. Several other useful chemicals are available. Electrode storage solution will help you to maximize the storage life of all your electrodes. Reference electrode refill solutions, as well as several types of gels are available.

pH Buffers

Sensorex buffers are accurate to within ± 0.01 pH units @ 25°C 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.
