CD 250/DSM

CD 250/DSM

Temperature-controlled holder for the Olis DSM 20, DSM 17, DSM 1000 and MultiScan CD Spectrophotometers
Product Overview

The CD 250/DSM provides temperature control, dry gas purging and magnetic stirring as needed to a wide range of cuvettes or other samples. This versatility is accomplished using a cuvette carriage which firmly mounts within the temperature-controlled tower of the CD 250/DSM. Cuvette carriages are available for several kinds of cuvettes, including those that are square, rectangular or cylindrical, as well as other samples such as small plates or films. Other carriages can be inexpensively designed as needed. Fused silica windows may be placed on each side of the sample or cuvette to minimize convection losses. Purchase this product directly from Olis to receive a fully integrated system.
