The overview 

The system is used for formulation research and development. The system consists of a test tube holder that can hold 45 50mL centrifuge tubes. Powder and/or liquid is added to the centrifuge tubes using a special dispensing unit and mixed by a magnetic stirrer. The quality of the added material is determined by the reduction method and the balance. The electrical conductivity of the system is monitored, and when it is stable, its pH value is measured and adjusted to the appropriate range. Then cover the tube and return it to the output rack. 45 formulations and pH adjustment processes can be completed in 8 hours.


Technical characteristics:

Dispensing (liquid and solid dispensing accuracy up to 1mg)

pH measurement (pH measurement range 0-14 pH ±0.01)

pH adjustment (with injection pump, acid/alkali add volume as low as 1uL)

Automatic calibration (weighing calibration and pH probe calibration)

Temperature measurement (system temperature measurement range -5 to 105°C ±0.1°C)

Conductance measurement (system conductance measurement range 10-200 mS/cm)

Mixing (magnetic stirring on when adding powder/liquid and pH adjustment)

Cleaning (pH probe and conductivity probe cleaning)

Distribution unit (simultaneous mixing and weight distribution monitoring, with self-mixing storage equipment)

Powder feed (two different feeders available for fine and rough samples)

Liquid feed (3 peristaltic pumps and 3 injection pumps)
