Shimadzu has a wide range of UV spectrophotometer accessories for a variety of applications and sample types. Among these are;

sample cuvettes (cells) and accessories for liquid samples and basic measurements, multiple cell holders, film holders, long path cell holders, hol

Multi-Cell Sample Compartment for 6 Cells

This compartment is a cell positioner that can hold up to six sample cells at a time. It has no temperature control capability. 

Long Path Rectangular Cell Holder

When the concentration of the sample is too low to be measured using a standard cell with an optical path length of 10 mm, a cell with a longer optical path length is used to enable measurement at the optimum absorption sensitivity. As shown in the figure, the absorption spectrum of potassium permanganate becomes clearer when a 100 mm cell is used instead of a 10 mm cell.

Film Holder

For transmittance measurements of thin samples such as films and filters

Constant Temperature Cell Holder

Sabit sıcaklıkta su sirküle ederek numune ve referans küvetlerin belirlenen ve istenilen sıcaklıkta tutulmasını sağlar. Sıcaklık aralığı: 5 ºC - 90 ºC

CPS-100 Cell Positioner, Thermoelectrically Temperature Controlled

This holder holds the sample cell at the desired, uniform temperature by circulating constant-temperature water. It accepts a pair of 10 mm square cells. 

TCC-100 Thermoelectrically Temperature Controlled Cell Holder

An easy-to-use constant-temperature cell holder that uses a Peltier element for electronic cooling. It does not require an external thermostatic bath or water for cooling. 

ISR-2600 / ISR-3100

Since light cannot penetrate opaque (solid) samples, it is reflected on the surface of the samples. As shown in the figure, incident light reflected symmetrically with respect to the normal line is called "specular reflection," while incident light scattered in different directions is called "diffuse reflection."


With integrating spheres, measurement is performed by placing the sample in front of the incident light window, and concentrating the light reflected from the sample on the detector using a sphere with a barium sulfate-coated inside. The obtained value becomes the reflectance (relative reflectance) with respect to the reflectance of the reference standard white board, which is taken to be 100%.
When light is directed at the sample at an angle of 0°, specular reflected light exits the integrating sphere and is not detected. As a result, only diffuse reflected light is measured. Models of integrating spheres with different angles of incidence are available, enabling measurement of both specular and diffuse reflected light in instances such as these.
