pH METER: Electrode Buffer Solutions & Tablets

NZD 12.75NZD 62.50 excl. GST

A variety of buffer solutions and buffer tablets for use with electrodes and pH Meters.

INFO: TAKING CARE OF pH METER ELECTRODES (PLEASE READ CAREFULLY.)
Many schools send pH meters to us for repair. We find that for about 95% of these, the pH electrode is at fault. Given care it will last for quite a while – up to 3 years – but even for the best electrode available it is considered acceptable if it functions for 1 year once activated. If not cleaned properly or left to dry out it may not be able to be resurrected. Try soaking in pH storage solution (refer to pH Storage Solution, cat.ALP 1825) for 24 hours. NEVER store a pH electrode in distilled water as the distilled water absorbs the ions out of the electrode electrolyte. By cleaning well after use and storing electrode in storage solution or a buffer solution of about pH4 it is possible to extend the electrodes life considerably. As pH electrodes age they get sluggish in their operation and take longer to settle on a reading. Given this more time is needed when calibrating and taking readings. If obtaining a reading takes too long this is an indication that the electrode need as replacing.
* Buffer solution satchets and tablets are a great option if you do not use your pH meter regularly. * Liquid buffer solutions start to deteriorate once the bottle is opened whereas, with tablets and satchets, you can make up a fresh batch as required.
