Compact, productive and easy to handle

The Thrombostat has been developed to be connected to almost any power source. 10–26V AC or DC current - or normal 115/230V mains voltage

Measurements can be started by using a start-pipette or a normal pipette with the new count-down timer. The developing coagulum is detected through the viscosity change. The measurement is, therefore, totally independent of the sample´s turbidity. A process control compares the measurement with internal standards and signals critical results. Even the smallest coagulum can be detected with this system.

The measuring system

A sensor monitors the ball rotating on the bottom of the cuvette. When a large coagulum is created, the ball is stopped on the wall of the cuvette. A softer, slower coagulum build-up either slows the ball´s movement or directs it towards the centre of the cuvette.
The following three parameters lead to the positive detection of a developing coagulum:
Firstly: the ball does not pass the sensor because a firm clot has stopped it at the edge of the cuvette.
Secondly: the ball is no longer detected, because it has been directed toward the centre of the cuvette
by a soft clot.
Thirdly: the impulse sensor detects a delay in the ball s speed caused by a change of viscosity in the sample.

The Computer

All analogue signals such as the temperature or the measuring signal are digitalized and controlled, monitored and evaluated by the internal computer. This computer can be updated with new software through the interface.
