Disposable Cuvettes

BioPhotonics
Nov 2010
ALine Inc.Request Info
 
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.

GLOSSARY
parallax
The optical phenomenon that causes relative motion between two objects when the eyepoint is moved laterally. When parallax appears in a telescope between the image and reticle, this indicates the image has not been formed in the plane of the reticle.
spectrometer
A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.  
spectrum
See optical spectrum; visible spectrum.
