Storage Solution

All Sensorex pH electrodes are shipped with soaker bottles or caps that are filled with a special soaking solution. This ensures that the electrodes are ready to work, right out of the box. No rejuvenation is needed. This soaker solution is a perfect balance of chemicals to maximize the life of any glass membrane pH electrode. Order part number S16.

Reference Refill Solutions and Gels

Several types of reference refill and gel solutions are available for your laboratory electrodes including S17, S18, S19 and S20 shown below.

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.
