Abstract:
A pipet comprisinga delivery reservoir including an inlet port that allows passage of liquid into but not out of the delivery reservoir, the inlet port adapted for attachment to a liquid source, and an outlet port that allows passage of liquid out of but not into the delivery reservoir, the delivery reservoir formed of a material substantially transparent to allow visual inspection of liquid level within the delivery reservoir; a disposal reservoir including an inlet port that allows passage of liquid into but not out of the disposal reservoir, and an outlet port that allows passage of liquid out of but not into the disposal reservoir, the outlet port adapted for attachment to a waste receptacle, and the disposal reservoir formed of a material substantially transparent to allow visual inspection of liquid level within the disposal reservoir; a tube having a distal end and proximal end, the distal end adapted for suction of liquid from and delivery of liquid to a vessel, and the proximal end in communication with the outlet port of the delivery reservoir and the inlet port of the disposal reservoir; and a vacuum port contiguous with the delivery reservoir and the disposal reservoir and adapted for attachment to a vacuum source, wherein application of a vacuum to the pipet via the vacuum port causes passage of liquid from the liquid source into the delivery reservoir via its inlet port and simultaneous passage of liquid from the vessel through the tube and into the disposal reservoir via its inlet port.
