Patent attributes
The present invention relates to an automated solution preparation apparatus having containers for holding solid reagents, a dispensing mechanism for dispensing the reagents to a balance, a supply for providing liquid to rinse the reagents from the balance into a chamber where additional liquids can be added, and a manifold connected to the chamber for dispensing the solution into receptacles. The chamber can have probes for monitoring properties of the solution, and heating and cooling jackets for adjusting the solution temperature. The present invention also relates to a method for using the automated solution preparation apparatus to prepare solutions of different concentrations and properties by dispensing reagents from containers into a weighing zone, where each reagent is separately weighed and rinsed from the weighing zone into a chamber, diluting the reagents with additional liquid solvent to prepare the solution and discharging the solution from the chamber into receptacles.
