Gilson Model 155 UV/VIS Detector

Gilson Model 155 UV/VIS Detector
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: 1.single wavelength
5.dual wavelength (155 and 156)
6.scan wavelength (155 and 156)

This item has a broken top hinge on the door/control panel as per close up image, though the door can still be closed. It also requires a new Visible Tungsten/Halogen Lamp Assembly (VIS) which is available from Gilson ( the Deuterium Lamp (UV) is starting correctly however so does not appear to need replaceing. With this in mind we are selling for spares/repair only and have priced accordingly.
