Red Tide UV/VIS Absorbance Spectrophotometer

Ready to go UV-VIS absorbance spectrophotometer system for $2,890

The RedTide-UV-Cuvetteis a low-cost, small- footprint lab spectrophotometer that's ideal as a general-purpose instrument for budget-conscious teaching and research labs. The system consists of the following”







Red Tide Spectrometer.  This versatile low cost unit has has a wavelength range of 200-850 nm, and utilizes a detector with 650 active pixels; that’s 650 data points in one full spectrum, or one data point per nanometer. Configured with a 25 µm entrance slit, the Red Tide offers ~2.0 nm optical resolution (FWHM). The Red Tide plugs into you computer through a USB port.







The spectrometer is coupled to our  USB-ISS-UV-VIS combination sample holder and deuterium tungsten light source (200-1100 nm). This sampling system holds standard 1-cm cuvettes for easy-to-perform absorbance measurements. The USB-ISS-UV-VIS allows you to control both the intensity of the tungsten bulb and a shutter via software. The USB-ISS-UV-VIS requires an external power supply (included).







Spectrasuite Software works on Mac, Linux or Windows based computers. Spectrasuite is loaded with features: real time absorbance spectra, graphical functions for annotations and printing, time series control and strip chart mode, peak finder, automatic wavelength calibration, mapping to absorbance standards, and much more.
