In-Spec® UV/Vis Spectrophotometer Standards

Setting the Standard for Spectrophotometric Analysis and Verification

The In-Spec® product line was designed to make UV/visible spectrophotometer validation accessible and easy for everyone.  This range of non-toxic, NIST traceable, materials includes photometric accuracy reference standards, wavelength accuracy filters, and stray light filters.   

 In-Spec® standards can be used as both a quality control check and to verify the operating procedure practiced by laboratory staff.  This allows the lab to ensure the data collected by the UV/Vis spectrophotometer is reliable.   All orders come with a detailed certificate of analysis with certified results.


Do you need a non-toxic alternative to potassium dichromate?

The In-Spec® standards are a ready-to-use suspended polystyrene polymer which is completely non-toxic.


Do sealed quartz cuvettes not fit into your labs budget?

The In-Spec® standards are available in a variety of pourable bottle sizes as well as the sealed quartz cuvette. 


Use the selection guide link below to help identify the best photometric accuracy standards for your application.  All the wavelengths on the selection guide will appear on the certificate of analysis.  Additional wavelengths can be added to the certificate of analysis upon request, free of charge.
