The life sciences have special requirements for instrument and method validation. In genomics and pharmaceutical chemistry in particular, limitations in sample availability and the very high cost of some reagents have led to the need to measure very small sample volumes. The need for high sample throughput is another pressure and has led to the development of highly automated procedures. The analytical equipment developed to meet these demands may not be compatible with conventional cell- or filter-based reference materials. This is, however, one of the most heavily regulated  fields in science, so reliable and traceable reference materials are a fundamental component of any quality programme, and essential for meeting guidelines such as GLP and GMP.

Starna has developed a range of reference materials tailored to the special needs of this important sector.

This is a rapidly developing field, and Starna is ideally placed to assist with the development of reference materials for use in novel applications. Please contact us with your  requirements.



This Reference Material was developed as a reliable, stable and NIST traceable reference  for the validation of nucleic acid purity measurements by the 260/280 nm ratio method.

The reference cell contains a solution of a synthetic material whose spectral  characteristics closely mimic those of DNA. By replicating an actual DNA sample, DNACON gives a reliable direct indication  of the quality of the overall measurement process. It is also available for use in microvolume instruments.

DNACON Microvolume References

DNACON Microvolume References 

Starna can supply DNACON specially packaged for  the qualification of dedicated drop technology and other low volume instrumentation, where sample volume is often below one  microlitre. Supplied in vials with either screw-cap or septum closures for ease of handling, they are also ideal for qualifying conventional instruments used with ultra- low volume cells such as the Starna  DMV-Bio cell.

Starna Green Microvolume References


Not all microvolume measurements are conducted on DNA, so the popular Starna Green reference is also available in vial format to provide a general purpose qualification for both wavelength and absorbance.
