UVISDrop micro-vol UV/Vis spectrophotometer


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 seconds.

1. UV/Vis measurement. Wide application, including nucleic acid (DNA/ RNA), protein, the concentration of other samples and counting of cell numbers.
2. A full spectrum measurement (200~ 850 nm) is available. The results of two light paths can be displayed simultaneously.
3. No need to dilute high-concentration samples.
4. No cuvettes or capillaries or other positioning instruments required.
5. Buttons of “Blank” & “Measurement” on the shell, no need to use mouse.
6. The light intensity is adjustable according to the sample concentrations to obtain stable measurements.
7. Controllable by the computer software with data storage function.
