The Hellma TrayCell is a fibre-optic Micro cell. It is designed for measurements of DNA/RNA samples and enables highly accurate analysis of extremely small samples with remarkable reproducibility. The dimensions of the cell are equivalent to a standard cuvette in order to work in almost all spectrophotometers.

Traditional spectrophotometrical analysis of nucleic acids is carried out in 10 mm cuvettes. Modern drop analysis uses light paths of 1 mm and 0.2 mm and it is thus not necessary to dilute the sample.
In applications with very high or very low DNA concentrations these light paths are often no longer sufficient. When using the Hellma TrayCell simply adjust the light path by exchanging the cap.
