Dispo Solid Dispensing
Dispensing materials in the solid state has been a challenge for
automation for years. Solid dispensing of samples with a wide range of
properties has proven even more difficult. To further complicate
matters, many experiments require sample mass in the microgram range.
BioDot's Dispo solid dispensing technology provides the ideal solution
to these challenges.
By coupling a pneumatically actuated z-axis with a
cylindrical probe containing a motorized plunger, which is adjusted
according to the desired mass, precise amounts of an array of powder
types can be aliquoted. The pneumatic action sends the probe down into
the source powder, compacting it into the cavity of the probe. With air
pressure as the probe's driving force, the amount transferred will
remain equivalent even as the source progressively decreases to minimal
levels. To dispense, the plunger is lowered down the shaft, thus
displacing the powder into a target vial or tray. Air pressure, probe
size, and transfer mechanism may be optimized accordingly based on a
compound's specific properties.
Key Benefits:
- Works with as little as 50 mg of starting material
- Mass dispense range of 100 ug to 20 mg.
- Non-vibratory operation prevents segregation effects.
