Abstract
In a preferred embodiment, a pipettor reservoir for particulate-containing liquid, including: a body portion; a shallow reservoir portion defined in an upper surface of the body portion; fluid-flow channels defined in the body portion to deliver the particulate-containing liquid from an inlet port to a plurality of openings defined in a bottom of the reservoir portion, the plurality of openings being arranged such as to agitate the particulate-containing liquid to keep particulate matter in suspension therein.
Claims4
A pipettor reservoir for particulate-containing liquid, comprising:
- (a) a body portion;
- (b) a shallow, single reservoir portion defined in an upper surface of said body portion;
- (c) an inlet port defined in said body portion;
- (d) a plurality of openings defined in said body portion and opening into, a bottom of said single reservoir portion;
- (e) fluid-flow channels including feed lines defined in said body portion to deliver said particulate-containing liquid from said inlet port to said plurality of openings in said feed lines, said plurality of openings being arranged such as to agitate said particulate-containing liquid in said single reservoir portion to keep particulate matter in suspension therein;
- and
- f) said fluid-flow channels are sized to maintaining approximately equal flow rates sufficient to keep said particulate matter in suspension and the total cross-sectional area of said feed lines is approximately equal to the cross-sectional area of said inlet port.
