Bechmann is a company with a long history. It has been internationally known for the manufacture and sale of clinical analytical instruments. Its own in the testing industry already has a very strong competitiveness, and in 2009 after the acquisition of the Japanese Olympus Life Sciences Division of the clinical testing business, so that Beckman in the field of clinical testing as a whole to a new level.
Although Beckman biochemical analyzer technology is relatively mature, but in some details also need to improve. For example: the circulating system of thermostat solution also belongs to the indirect air bath. The air between the colorimetric cup and the thermostat solution is also susceptible to external temperature effects. At the same time, the constant temperature solution needs to be changed regularly, which is relatively expensive. The spiral stirring bar has a large contact area with the reaction solution, which is easy to cause carryover contamination. In addition, the inherent reaction time of AU series biochemical analyzer is 8 minutes and 15 seconds, which requires project calculation for individual projects.

Hitachi automatic biochemical analyzer is manufactured and operated by HITACHI, and is an important equipment for clinical chemistry testing in hospitals at all levels. However, the Hitachi refrigeration system uses "compressor" refrigeration technology, which can cause vibration during the refrigeration process and affect the accuracy of colorimetric results. The dispensing system uses a "syringe" for sample addition, and the accuracy of sample addition is low for an internationally known brand like Hitachi.

The series offers excellent performance and proven technology. This has made the Toshiba TBA-FR series of fully automated biochemistry analyzers one of the most popular brands in its class and has a wide range of users around the world.
However, Toshiba's biochemistry analyzer dispensing system uses a "syringe" to refill samples. This is a low accuracy for an international brand like Toshiba. The stirring system uses piezoelectric vibration stirring, which is not uniform and prone to mechanical failure.
