The quality and health benefits of beverages such as wine and tea are associated with the anti-oxidant properties of naturally occurring phenolic compounds. Measurement of these strongly UV absorbing components is not possible in standard cuvettes without dilution, complicating the routine determination of a variety of samples, and potentially altering the results.

The SpecVette™ permits measurement of red wine samples across the entire spectrum, from 220 to 900 nm, in a single disposable cuvette. With the high resolution (0.02 nm) and rapid spectral averaging possible with Ocean Optics HR4000 spectrometer, errors of 2% or less are possible, permitting multi-component analysis of samples of interest.

ALine's short path SpecVette™ is available in 0.25, 0.50, 0.75, and 1.0 mm path lengths, useful for a variety of sample types. The cuvettes are easily filled by capillary action using a simple disposable dropper or they can be filled and aspirated using a 20- 200 uL pipetter. The SpecVette™ slides into a 1 cm x 1 cm sample holder for use in a standard spectrometer. The SpecVette™ is UV transparent, and disposable so that no cleaning is required, and no chance of introducing contamination to ruin results.

A selector guide for a wide range of ALine's custom "Build-Your-Own-Cuvettes" ™ is now available on the ALine web site. Consult with ALine for additional configurations.
