Nano Spectrophotometer LNS-A21 with full spectrum light covers wide wavelength range of 200 to 500nm. It requires only 0.5 - 2.0 µl micro-volume sample for measurement which takes place within 5 seconds. It utilizes CCD detector, Xenon flash lamp as light source which has high stability and long operating life. It is used to detect micro volume quantities of nucleic acids and other concentrated or dilute components.
