Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
An apparatus for reconstituting a dry material that has been stored in a storage container without removing said dry material from said container, comprising: an automatic dispensing means for automatically dispensing a predetermined amount of a solvent into said container, wherein said dispensing means dispenses said solvent at a flow rate of at least approximately 1 milliliter per second; and an agitator means for agitating said solvent and said dry material in said container adjacent to said dispensing means.
Claim 2
Independent Claim
79 words
An apparatus for reconstituting a dry material that has been stored in a storage container without removing said dry material from said container, comprising: an automatic dispensing means for automatically dispensing a predetermined amount of a solvent into said container, wherein said dispensing means dispenses said solvent at a flow rate of at least approximately 1 milliliter per second; and an agitator means for agitating said solvent and said dry material in said container adjacent to said dispensing means.
Claim 3
Dependent Claim
40 words
An apparatus according to claim 1, wherein said automatic dispensing means comprises: a dispenser control means for activating said automatic dispensing means and for automatically deactivating said automatic dispensing means when said predetermined amount has been dispensed into said container.
