Where to find the LOT code
What is a CoA?
A certificate of analysis (CoA) belongs to one lot. It states the measured pH, mV or µS/cm of that lot. You use it for the measurement, for your records or for an inspection.
What is the difference with an SDS?
The safety data sheet (SDS) tells you how to use, store and dispose of the solution safely. That sheet is the same for every lot. The CoA is the measurement of your bottle or sachet.
You can download the SDS on the SDS page.
You can request a COA for pH buffer solution, ORP buffer solution and conductivity standard. On the 250 ml bottle and the 60 ml bottle the lot code is on the label next to the expiry date; on the 20 ml sachet you will find the expiry date (MM/YYYY) and a letter; enter these in the form.
