Caps for TrayCell
Traditional spectrophotometrical analysis of nucleic acids is carried out in 10mm cuvettes. Modern drop analysis uses light paths of 1mm and 0.2mm 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 TrayCell from Hellma Analytics simply adjust the light path by exchanging the cap. Cap with integrated mirror to change the light path.
