M-402 DH3000 Nucleic Acid Analyzer is a basic micro-volume UV spectrophotometer specifically designed (only three types of wavelength: 230nm, 260nm and 280nm) for the measurement of nucleic acids and proteins

Features:
Flexible data output--The data can be printed with built-in printer, the data can output via SD-RAM Card and USB memory
Micro-volumes Easy & Fast--Only require 0.5~2μl samples to accurate determinate of nucleic acids, proteins
Long life & No consumables--Xenon flash lamp, 10 flashes, up to 10 years, no cells or cuvetes, no dilitions and expensive comsumables
No computer required--Touch screen and panel operation with built-in controls and software, without computer
Easy & Fast-- Direct, easy measurements within 5 sec No dilutions for samples and no warm up
Measure nucleic acid & protein--Measure nucleic acid concentration at 260nm, and purity using the 260/280 ratio. Measure purified protein concentration at 280nm
