The UTS 4.3 is the universal tablet testing instrument created by the Kraemer Elektronik GmbH based in Darmstadt. The instrument is capable of determining the breaking force, the diameter/length, the thickness and the weight of tablets in a fully automatic manner. With the optional OZB (Oblong-Zentriersystem – Oblong Centering System) unit, it can also be suitable for width measurement. The UTS 4.3 is available in two versions: the LAB ones for test laboratories, where the tablets to be measured must be placed in a container at the start. The various IPC instruments are suitable for direct measurements next to the tablet presses receiving the tablets directly from the press.
The tablets first get into the moving feeder and then one by one into the carousel. The rotating carousel transports the tablets into the measuring positions. For measuring oblong tablets, it is recommended the use of the OZB, which can hold the tablets in the correct position and is also suitable for measuring the width of the tablets. The measurement of the breaking force is performed at a constant speed of 0.35 mm/sec. The load cell of the instruments can be calibrated with calibrated weights or with a dynamic manual calibration unit within the entire measurement range. The UTS 4.3 LAB can be supplemented with a 12-container feeder and a 12-container collection system.
One way to operate the UTS 4.3 instruments is to control and collect data by using the 7’’ touch screen. The measurement parameters, the tolerance and acceptance ranges can be set for the products. The large internal memory allows the storage of 
approx. 10,000 products. The measured values can be displayed graphically and histograms can also be displayed. The methods and results are stored in a database, which can be backed up and be restored as well. The instrument also has USB and network connectors. The results can be backed up onto a portable data storage device, or it is also possible to mount a network drive. In the latter case, the results can be saved into a designated network directory in CSV or XML format, thus making them readable to LIMS systems (optional).
The UTS 4.3 tablet testers can also be controlled with the Ph21 PC software. The Ph21 fully complies with the requirements of the 21 CFR Part 11, allowing for detailed user authorization settings. The measurement parameters, the product data and the measured results are stored in a database, which provides a secure and convenient way to access all data.
