ND-2800-ODJ Nano DOT Nucleic Acid Analyzer

Product Description

ND-2800-ODJ Nano DOT Nucleic Acid Analyzer is a stand alone, easy-to-use and compact spectrophotometer that is ideal for quick measurement of concentration and purity of nucleic acid and purified protein samples by using 260 nm and 280 nm. ND-2800-ODJ has an additional feature, OD600 measurement, which allows quantification of bacteria concentration in liquid suspension by using cuvette.

Samples of 1 μl to 2 μl can be measured by pipetting directly onto lower pedestal without requiring absorption cell or cuvette and the results can be obtained in less than 8 seconds. The newly 7-inch colour touchscreen and intuitive graphical interface make operation easy and user friendly. Results can be printed with the built-in printer or exported via USB flash drive.
