The new heavy-duty sample changer ensures the automated filling of challenging samples. It has a wide temperature range and can carry out fast measurements of challenging samples. Automated cleaning and drying increases the sample throughput in a laboratory and operators are not required to handle hot syringes to fill the sample into the measuring instrument. The sample can be directly filled out of the heated sample vessel and placed into the sample changer, which ensures maximum ease of use. For operating convenience, the user also has no contact with the cleaning solvents, as two bottles can be connected to the measuring system.
