Gilson's 15X Series of UV/VIS Detectors deliver versatile, rugged detection for your HPLC. The optical design lets you optimize the detection of your sample at any wavelength from 190 to 700 nm.

•     Interchangeable flow cell design accommodates capillary to preparative HPLC applications

•     The detectors have a sensitivity range of 0.001 to 2.0 AUFS (Absorbance Units, Full Scale)

•     Controlled via Gilson’s UniPoint™ System Software or choose stand-alone keypad control with the 151 and 155 models

•     Stores up to 10 detection methods

•     Choose from the following modes to specify detection conditions and basic operating parameters:

     – single wavelength

     – file

     – status

     – setup

     – dual wavelength (155 and 156)

     – scan wavelength (155 and 156)
