Control device for automatic liquid handling system
First Claim
1. An automatic liquid handling system comprising:
- a dispensing tip container having a plurality of holding portions for holding a plurality of dispensing tips;
a dispensing head having attachment portions to which at least one dispensing tip selected from the plurality of dispensing tips is attached, wherein when one or more dispensing tips are attached to the attachment portions, the dispensing head is capable of performing sucking and expelling operations for sucking liquid in or expelling the liquid out from the one or more dispensing tips;
moving means for moving the dispensing head;
a reagent container that holds at least one reagent;
a microplate formed with a plurality of wells for holding specimen;
a control device that controls the sucking and expelling operations performed by the dispensing head and also controls the moving means to control movements of the dispensing head, the control device having input means for inputting one or more processes to be executed by the dispensing head; and
time measuring means for measuring time starting from dripping the reagent into selected wells on the microplate by the expelling operation performed by the dispensing head and triggering dispensing a stop solution at a predetermined time based on the measuring.

Abstract
In reagent reaction experiments using microplates, a desired period of time can be set for determining the time to introduce a reaction stop solution after introduction of a reagent. The set time is measured starting from the introduction of the reagent and the reaction stop solution is introduced immediately after expiration of the set time. A control device for an automatic liquid handling system having the above-described reaction time managing feature is also provided with a self-diagnosing function that is capable of determining whether scheduled processes are executable or not during the time set before execution of the processes and informing an operator of the results of determination.

10. An automatic liquid handling system comprising:
-
a dispensing tip container having a plurality of holding portions for holding a plurality of dispensing tips, the holding portions being arranged in a matrix form defined by rows and columns; a dispensing head having attachment portions to which a plurality of dispensing tips are attached, wherein when dispensing tips are attached to the attachment portions, the dispensing head is capable of performing sucking and expelling operations for sucking liquid in or expelling the liquid out from the dispensing tips; moving means for moving the dispensing head; a reagent container having a plurality container portions for storing a reagent and having a plurality container portions for storing a reaction stop solution; a microplate formed with a plurality of wells for holding specimen, the wells being arranged in a matrix form defined by rows and columns; a control device that controls the sucking and expelling operations performed by the dispensing head and also controls the moving means to control movements of the dispensing head, wherein the control device includes input means for inputting one or more processes to be executed by the dispensing head, time selling means for setting a period of time between introduction of the reagent into a row or a column of the microplate and introduction of the reaction stop solution into the row or the column of the microplate; and time measuring means for measuring a period of time starting from the reagent is dispensed into the row or the column of the microplate so that a dispense reaction will not be stopped before the measured period of time has reached the set period of time. - View Dependent Claims (11, 12, 13, 14, 15)
