DNA RNA Reference Set

Buy on-line, White Bear Photonics offer Starna reference standards for DNA/RNA ratio calibration.

260/280 Ratio Validation Reference

When running DNA or RNA purity analysis on your spectrophotometer it is important to assure that your instrument is working correctly. Our DNA/RNA validation standard is a permanently sealed quartz cell which contains a stable solution which mimics the 260/280nm ratio of DNA and RNA. The reference is supplied with a certificate which lists the expected 260/280nm ratio of the cell and the confidence limit of the ratio. The validation analysis is performed by our ISO 17025 accredited laboratory and is traceable to NIST.
