The picture on right shows the Adaptive Precision Powder Dispenser. In this novel electromechanical device, powder is stored in a conical cavity inside the dispenser. A vortex is induced using pressurized nitrogen inside the dispenser to force the powder out of the dispenser and into a cavity in the slider attached in the bottom of the dispenser. This cycle of pressure is alternated with applying vacuum inside the dispenser conical cavity to break up powder agglomerations. After pre-determined cycles of pressure and vacuum, the slider is slid into the dispensing position, and the powder is ejected from the slider cavity using vibration and gentle nitrogen pressure into a septum sealed container.
- This dispenser can be adapted via software to dispense a range of powders with widely varying properties in the 0-100 mg range within ± 5%.
- Powders are differentiated by dispensing parameters, which are stored by in a database, the entry into which is identified by means of a bar code label on the dispenser.
- Unique design of the dispenser prevents the build-up of electrostatic charge inside the powder dispenser.
Possible application areas of this technology:
- Precise powder dispensing for a powder filling line.
- Dispensing lyophilized microorganisms.
- Dispensing resins for combinatorial chemistry
- Distributing compounds in the compound distribution center
- Can be used to fill active pharmaceutical ingredients directly into vials for accelerated clinical trials, thus avoiding time-consuming excipient compatibility studies.
- Can be used to dispense powders for Solubility Screening
- Can be used to dispense powders for Salt Selection etc.
- Can dispense powders in sealed microtiter plates and septum sealed vials
- Any other application, when powder is to be precisely delivered in a CONTROLLED ENVIRONMENT.
