Leírás
UVISDropTM gives highly accurate full spectrum measurements with micro-samples (spectrum range: 200~ 850 nm). Simply pipette 0.5~ 2.5ul sample onto the pedestal, laying down the sampling arm, UVISDrop can automatically complete the measurement within 5 second
- UV/Vis measurement. Wide application, including nucleic acid (DNA/ RNA), protein, the concentration of other samples and counting of cell numbers
- A full spectrum measurement (200~ 850 nm) is available. The results of two light paths can be displayed simultaneously.
- No need to dilute high-concentration samples.
- No cuvettes or capillaries or other positioning instruments required.
- Buttons of “Blank” & “Measurement” on the shell, no need to use mouse.
- The light intensity is adjustable according to the sample concentrations to obtain stable measurements.
- Controllable by the computer software with data storage function.
