Custom Standards

You may have a unique application that requires verification of certain absorbance values or wavelengths that aren’t listed for our stock products. Our experienced staff has the ability to work with you to develop a reference standard that will validate your instrument for your application.

Please call technical support for assistance.

In order to facilitate custom standard development there are several key pieces of data that are required.
With this information, technical support will be able to quickly assess your needs.

• Wavelength(s) of interest
• Pathlength
• Instrumentation make and model
• Desired or sample absorbance range

Our problem-solving lab team is available Monday through Friday from 7:30 am to 4:00 pm EST.
