Patent ID: 8609040

Claim:
An apparatus for generating a denaturation graph from two known solutions, comprising: a first known solution; a second known solution; a multi-well plate comprising a plurality of sample wells; a movement system comprising a unit having at least three cannulas, and a plurality of actuators to move said unit to a specific position on a grid, at least three vertical actuators disposed on said unit, each to control vertical movement of a respective cannula, wherein said at least three cannulas are positioned on said unit such that all of said at least three cannulas may access a sample well through actuation of said vertical actuators without actuation of said movement system; a fluid system in communication with said cannulas, allowing said cannulas to draw in and dispense fluid; a measurement system for measuring a characteristic of a sample; a controller having a storage element comprising instructions, which when executed: actuate said movement system to move said unit to said first known solution; actuate said fluid system to draw said first known solution into a first cannula; actuate said movement system to move said unit to said second known solution; actuate said fluid system to draw said second known solution into a second cannula; actuate said movement system to move said unit to a first sample well; actuate a first vertical actuator, a second vertical actuator and said fluid system to dispense said first known solution and said second known solution into said first sample well according to a predetermined relationship to create a first volumetric ratio of said first and second known solutions; actuate said movement system to move said unit to a subsequent sample well; and actuate said first vertical actuator, said second vertical actuator and said fluid system to dispense said first known solution and said second known solution into said second sample well according to said predetermined relationship to create a second volumetric ratio of said first and second known solutions.
