V&P Scientifics' unique Bubble Paddle stirrers (US Patent #6,461,034)
allow you to mix and suspend cells, resins, slurries, beads, magnetic
beads and particles and even glass beads. Our reservoirs that are
specifically designed to allow pipetting while the Bubble Paddle is spinning at
speeds in excess of 3,000 RPM. This assures that even very dense
particulates like glass beads are kept homogeneously dispersed during
pipetting. Thus the first aliquot and the last aliquot pipetted contain
the same number of beads/particulates. We have also incorporated a "ducted"
design into the bottom of the reservoir that enhances fluid movement by
channeling it through a series of ducts in the bottom of the reservoir. We
also incorporate pipet tip depressions between individual bubble features
on the paddle so that even the dregs of an expensive reagent can be dispensed
with minimal dead volume loss. We make the Bubble Paddle Reservoirs to be
compatible with 4 channel pipettors, 8 channel pipettors, 96 channel pipettors, and even 384 channel
pipettors.
Our Bubble Paddle Stirring systems can be powered by:
1.
A V&P
Magnetic Alligator Tumble Stirrer
2.
A V&P Magnetic Clutch/DC motor
3.
A V&P Direct Drive Sealed
Bearing Reservoir/DC motor
The V&P Direct Drive Sealed Bearing system is unique in that it
does not use magnetism to stir the reservoir, thus it can be used to keep
magnetic beads in suspension.
