Spectrum Chromatography Model 280 UV Detector

PRODUCT DESCRIPTION

This fixed wavelength flow-through spectrophotometer is specifically designed for chromatography use

The instrument uses a long-life, low-pressure mercury lamp that offers 6000 hours of operation. Due to the short warm-up time of 10 minutes, the lamp can be turned off whenever not in use. The unit features a direct reading digital output and a dual beam optical system that allows the automatic subtraction of a solvent background even in the presence of a rapidly changing gradient. The instrument is cold room compatible, and can be used with three available flow cells.

A 5mm pathlength dual flow cell is included with the instrument. It provides an illuminated volume of 34µL and a hold-up volume of 134µL per flow path. The optional 2mm pathlength dual flow cell provides an illuminated volume of 14µL and a hold-up volume of 54µL per flow path. The optional 10mm pathlength dual flow cell provides an illuminated volume of 68µL and a hold-up volume of 268µL per flow path. The optional connection cable connects the UV detector to the CF-1 Fraction Collector (see 21501-310 series) so that a tick mark will be placed on the chromatogram with every tube change and the peak separator in the fraction collector can be used to detect peaks.

Ideal for routine UV detection and quantitation, the economic instrument is supplied ready-to-use with a detector for use at both 254 and 280nm, a digital display, a 5mm pathlength dual flow cell, and a cable for connection to a recorder.
