Cary 4000 UV-Vis Spectrophotometer (Agilent Technologies)

The Cary 4000 is a high-end double beam UV-Visible spectrophotometer that offers a huge versatility of set-ups and accuracy.

Applications:

Characterization of liquids and films in the range 175-900 nm, and also powders by means of a diffuse reflectance accessory (DRA) in the range 300-800 nm. This device can be setup for performing reflectance, transmittance or absorbance measurements of diffuse, specular, or mixed samples, not only powders, but also other highly diffractive samples, like nanoparticles dispersions, rough films and surfaces, etc.

A liquid cell holder can be setup for performing variable temperature experiments using a thermostatic bath circulator.
