NuDrop micro-vol. nucleic acid spectrophotometer


NuDropTM is a sophisticated spectrophotometer designed for nucleic acid measurements. The lamp source is UV-LED. It can accurately measure nucleic acid samples, and is no need to dilute high-concentration samples. Simply pipette 1.5~ 2.5ul sample onto the pedestal, laying down the sampling arm, NuDropTM can automatically complete the measurement within 3 seconds.
