The SpecVette disposable cuvettes manufactured by Aline Inc. feature
a short path length and fit standard spectrometers. Available in path lengths of
250, 500 and 1000 μm, they exhibit UV transparency to 220 nm. They feature
an easy-to-fill pipette tip port and dual chambers. The low-volume precision cuvettes
for absorbance applications offer an economical alternative to quartz cuvettes.
They require only 25, 50 or 100 μl of sample solution, deliver precise path
lengths to ±1%, and exhibit no parallax as found in molded cuvettes. Applications
include opaque samples that produce a lot of scatter and skew the baseline, and
optically dense samples that change their spectrum to be in the correct dynamic
range if the sample is diluted. They also can be used to eliminate dilution errors
for protein quantitation.
