Test Tube Holder for test tubes with diameters between 11mm and 17mm

To extend the range of samples that you can analyze, we offer a wide range of sample holders. The rectangular and cylindrical long-path cell holders are ideal for sensitive measurements on dilute samples where the extra pathlength is important. For the chemist, the test-tube holder provides a convenient method of sampling in-situ without having to decant the sample into standard cells. Finally, extend your measurement capabilities to include solid materials with the solid and variable-angle sample holders.
