B104 pH Buffer Solution, pH 4.01 Buffer (Red), 1 pint (473ml) by Sensorex

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.

Features:

• Choice of pH 4.01, pH 7.00 and pH 10.00 or custom formulations
• Pint, Quart and Gallon Sizes
• NIST Traceability Certificates Available at Additional Cost
• Private/OEM Labeling Capability
• Color-Coded for easy recognition

AI1107 3M KCl Storage Solution 4 oz. by Apera

This storage solution is for conditioning and extending the service life of regular pH and ORP electrodes/testers/sensors. pH/ORP electrodes that are stored dry will lose their sensitivity and accuracy temporarily. They can be restored by soaking in the KCL solution. Keeping pH/ORP electrodes stored in the storage solution when not in use is a recommended practice. The storage solution works well for Apera Instruments regular pH and ORP meters and electrodes e.g. PH20, PH60, 201T-F, 301PT-C.
