How do I obtain the calibration certificate?

This does not come with a NIST traceable calibration certificate supplied by the manufacturer. However, a certificate of analysis is available on Cole-Parmer.com. Enter the Cole-Parmer part number in the search box at the top of the page. Once of the item page, enter the lot number into the certificate of analysis box.
