In the case of concentration determinations in microplates, the measurement is made vertically and the layer thickness of the sample to be measured is dependent on the sample volume. Even with smaller sample volumes, the resulting layer thicknesses are sufficient for precise measurement. At a constant sample volume, concentrations can be determined with the aid of a calibration curve.

Properties:

• Optical window down to 230 nm ideal for nucleic acid determinations at 260 nm/280 nm
• For measurements of protein concentration at 280 nm
• Transmission measurements with UV light up to 230 nm
• DMSO-resistant
• Stored at -20 °C without any problem
