Red Tide UV/VIS Absorbance Spectrophotometer

SE-REDTIDE-UV-CUVETTE 
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.

 

 

 

 

 

 

CVDUV1S  You get one pack of 100 disposable UV cuvettes. These cuvettes have 4 clear sides, are 1.5 – 3.0 ml volume and a1cm pathlength,
