Calibration Solutions

calibration-solutions-1Buffer Solutions

pH buffers standardised at 250C and colour coded for easy recognition.

Our buffers are electrometrically checked against standard primary buffer solutions in accordance with NIST using traceable reagents. Certificates of analysis are available on request.

Available in pH4, pH7, & pH10 – 500ml or 1Litre bottles.

conductivity-standard-1Conductivity Standard

Conductivity is based on values published in APHA, AWWA, WEF  Standard Methods for Examination of  Water and Wastewater 22nd Edition.

Our conductivity standards are referenced to Standard Conductivity Solution prepared from potassium chloride 99.99%+ traceable to NIST Standard Reference Material  and using equipment calibrated and traceable to national standards.  Certificates of analysis are available on request.

zero-oxygenZero Oxygen Standard

Used for zero point calibration of dissolved oxygen sensors. Contains 5% sodium sulphite in deoxygenated water with a trace of cobalt chloride.

Available in 500ml

electrode-cleaningElectrode Storage Solution

Used for storage of pH electrodes.  pH glass electrodes need to be kept clean and moist at all times. If an electrode dries out during storage, it will require a regeneration procedure to restore the sensitive hydrated glass layer at the tip of the sensor.  Proper pH electrode storage will maximise electrode performance and extend electrode life.

Contains potassium chloride and potassium hydrogen phthalate.

Available in 500ml

electrode-cleaningElectrode Cleaning Solution

A mild cleaning solution for pH glass electrodes. Not suitable for removing oil and grease deposits from heavily contaminated electrodes.

Available in 500ml
