Recommended cuvettes and cleaning solutions


The cuvettes we use with the CD spectrometer are all manufactured by Hellma, Inc. While their are certainly other companies that manufacture cuvettes, we know that the ones from Hellma will fit into spectrometer without additional adapters. Circular Dichroism is a sensitive phenomena, so the optical quality of the cuvette is another important factor. The cuvettes listed below are all made of high grade quartz.

The following cuvettes can be purchased through Hellma, Inc. They are also available through Fisher Scientific.
