Nano Drop Spectrophotometer STA-200 is a full wavelength (190-1000nm) ultra micro volume UV-Vis spectrophotometer. It can fast measure nucleic acids, protein and cell solution. Meanwhile, its easy-to-use, sample volume requires only 0.5 ~ 2 μl, it’s not required preheating and it can fast clear out residue sample, no cuvee or other sample positioning fixture, no dilution etc. STA-200N Ultra micro volume spectrophotometer, easy-to-use, pipette directly onto the sample measure detect head, close it to start measure. It can directly wipe out residue sample or recycle after completing measure. STA-200N has been common instrument of many labs. STA-200N ultra-micro volume spectrophotometer is mainly used to measure nucleic acids, protein. It uses high energy pulsed xenon light source give spectral measure of 230nm, 260nm, 280nm.STA-200N operate on Android software with 7 inch capacitive touch screen, it’s not require to connect to PC but operate individually, and it can output by USB, and it’s convenient to make analysis and storage by users.
