CD 250/UV1280

Temperature-controlled holder for the Shimadzu UV-1280 UV-Vis Spectrophotometer for a wide variety of cuvette types or solid samples
Product Overview

The CD 250/1290 for the Shimadzu UV-1280 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 250/1280. 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. Removable strain-free fused silica windows are placed on each side of the CD 250 to minimize convection losses. Depending on the carriage design, an additional optical port may be available at 90 degrees to the excitation. Use the CD 250/1280 for work in the biological range of 0 °C to 105 °C. With the correct carriage design and sample, extend temperature ranges to below -40 °C or up to 150 °C. Operate the TC 1/Single Temperature Controller using the menu button on the front of the controller.
