The NanoEx Photometer is designed for simple, convenient and reliable work with sample volumes from 0.5 μL. Four wavelengths: 260, 280 and 360 nm for optical density measurements in droplets and 600 nm for turbidity measurements in a conventional cuvette. NanoEX Features Automatic lid closure - no need to set the optical path length - measurement takes place automatically at several points; special stand for pipettes and built-in video camera for precise sample application on the well; no PC connection required; built-in Bluetooth for data transfer to a smartphone or printer; Technical characteristics Working volume of the sample, μL - 0.5; Optical path length (determined automatically), mm - 0 , 2-1; measurement time, sec - 5; cycle measurement time, sec - 10; measurement range, nm - 260, 280, 360 (baseline correction) and 600 (turbidity measurement in a conventional cuvette); detection limit - 4 ng / μl dsDNA; maximum concentration - 7.5 mg / ml dsDNA; absorption range - 0-150; error (at 1 mg / ml dsDNA),% - 3; light source - LEDs; detector - silicon photodiode; built-in software; color touch screen; base dimensions, mm - 148 × 179; weight, kg - 1.5.
