- There were various problems in the stirring under the closed environment.
- Since the reaction solution corrodes the metal, I wanted to use PTFE instead of SUS (metal) for the stirrer.
- With a general PTFE seal, there was concern about the air tightness because the rod has a penetrating structure.Further, there was a problem that a part of the rod was scraped during stirring and the scrapped pieces was mixed in the reaction solution.
- And, when the stirring speed is increased, there was a problem that the reaction solution scatters.

Stirring under the closed environment
Prevents contamination and stabilizes the synthesis of closed systems
- Since the UZU completely separates the power unit and the stirring unit, there is no concern about airtightness. Also, the rod is no longer scraped during stirring.
- When centrifugal stirrer is used, the reaction solution do not scatter even when stirred quickly.
- By combining UZU and centrifugal stirrer, stable stirring under a closed system become possible, and a uniform synthetic product can be obtained.
Since it is composed of PTFE, it has high corrosion resistance.
Highly corrosion-resistant materials such as PTFE are used for the liquid and gas contact parts.
Since the metal parts are not exposed, it can also be used for stirring that generates acidic vapors.
It is possible to hold the stirring rod firmly by the mechanism that can stop the shaft, which is uniquely developed.
It can be widely used in highly corrosive reaction.
Robust sealing performance by magnetic coupling
A magnetic coupling with excellent airtightness is used to transmit power.
Unlike general stirring seals, the O-ring for sealing does not come into contact with the drive unit, so robust sealing performance is stably maintained.
Sinc ceramic bearings are used to hold the drive shaft, it is possible to prevent the generation of abrasion powder.
It stabilizes the atmosphere inside the container and contributes to uniform synthesis results even in synthetic reactions involving nitrogen substitution, water-reactive reactions, and reaction systems that use volatile reagents.
Combination with centrifugal stirrer
By using SEALING MIXER UZU in combination with a stirrer using centrifugal force, the stirring efficiency of the solid-liquid two-phase is improved.
The flow from the bottom prevents the solid phase from precipitating and disperses efficiently.
In addition, the liquid level can be kept calm, minimizing solution scatter and air entrainment.
It also supports customization of the controller that emphasizes the number of revolutions rather than torque according to the characteristics of the centrifugal stirrer.
It is ideal for stirring that includes a catalyst and reaction that causes a solid phase to precipitate.
