UTS4.1 – Universal Tablet Testing System


Automatic tablet testing systems


UTS 4.1 is a universal and fully automatic tablet testing system developed for industrial applications. The Kraemer UTS 4.1 is the proven model from a series of Kraemer tablet testing systems tested over many years – developed and designed in close cooperation with the pharmaceutical industry and major tablet press manufacturers.


The UTS-Series splits into various models, all tablet tester models are testing the main physical parameters of tablets:

Hardness (breaking force)
Diameter / Length
Width (optional)

With the Ph21 software the system becomes 21 CFR Part 11 compliant.

Three stage dedusting

In the patented feeder chute which separates the tablets, tablets are also dedusted before testing. After the separation the tablets are fed one by one on a slide into the starwheel (star-shaped transfer element). Each tablet is detected by a dust-insensitive sensor.

Two additional tablet dedusting sections after the separation, keep the tablet testing stations clean and guarantee reliable test results.

Remaining dust and debris are collected in a special dust container under the separation slide.

Self cleaning feature

To keep the track where tablets are moved through the testing stations clean, inside the starwheel are 24 PTFE scrapers shuffling dust and tablet crumbs to the waste bin.


The smart design of the transport starwheel alignes, centers and transports the tablets through the different measuring stations: weight, thickness, diameter and hardness.

Handling of unusual tablet shapes

The transportation starwheel which moves tablets through the different testing station is available with many different executions and can be customized.

Online tablet testing at the tablet press

Use the Kraemer UTS4.1 as an online monitoring device connected to your tablet press or capsule filler. Sampling can be initiated either from the production machine or via our Ph21 software.
