A five-bottle pack to calibrate, clean and store your pH electrode
The Environmental Express pH Solutions Pack puts everything you need to look after a pH electrode in one order: pH 4.01, 7.00 and 10.01 calibration buffers, an electrode cleaning solution and an electrode storage solution. Each bottle holds 500 mL.
Environmental Express states the pack costs over 25% less than buying the same solutions separately.
Key features
- Complete kit: Three buffers, a cleaning solution and a storage solution, so you can calibrate, clean and store from one pack.
- Colour-coded buffers: pH 4.01 is red, pH 7.00 is yellow and pH 10.01 is blue, for quick identification in a busy lab.
- Calibration help on the label: Each buffer bottle has a pH/temperature table printed on it for accurate calibrations.
- Quality and traceability: Environmental Express states the buffers are manufactured under ISO 9000 quality guidelines and are traceable to NIST standards.
- Electrode care: The cleaning solution is Oakton® Electrode Cleaner, which is safe for pH and ORP probes and works on junction-clogging proteins and oils. The storage solution helps keep probes hydrated and restores hydration after cleaning or dry storage.
Ideal for
- Labs that calibrate pH meters on a regular schedule and want one item to reorder
- Routine maintenance of pH and ORP electrodes to help extend their life
