Simultaneous aspirator and dispenser for multiwell plates and similar devices
First Claim
1. A method of simultaneously dispensing and aspirating a sample to a testing device having at least one well, comprising the steps of:
- positioning an aspirating and dispensing device having an aspirating port and a dispensing port proximate to the testing device such that the aspirating port and the dispensing port in the device are placed into the at least one well;
activating a control mechanism to thereby cause a sample to enter the well via the dispensing port and simultaneously aspirating the sample from the well.

Abstract
A device for simultaneously dispensing a solution containing a sample to a test device and aspirating the sample from the device. In one embodiment the device is hand-held and includes a control mechanism, e.g., button for activating the dispensing and aspiration of the sample. The testing device may take the form of a multi-well plate with a plurality of wells arranged in rows and columns, with the bottom of the wells formed as a photonic crystal biosensor. The device can be configured with dispense and aspirate manifolds and associated dispense and aspirate ports which are positioned in all the wells along a row or column of wells so as to simultaneously aspirate and dispense solution to all the wells in a row or column of the multi-well plate.
