Simultaneous aspirator and dispenser for multiwell plates and similar devices
First Claim
1. A device for simultaneously dispensing and aspirating a sample to a testing device having a well, comprising:
- a) a body having a portion thereof adapted for engagement with the testing device;
b) dispense tubing coupled to the body for receiving a sample from a source;
c) aspirate tubing coupled to the body connected to a source of vacuum;
d) a dispense manifold connected to the dispense tubing having at least one dispensing port;
e) an aspirate manifold connected to the aspirate tubing having at least one aspirating port wherein the dispensing port and the aspirating port are configured in close proximity to each other whereby the aspirating port and dispensing port are positioned in or proximate to the well of the testing device when the body is positioned proximate to the testing device; and
f) a control mechanism for controlling movement of the sample from the dispense tubing to the dispense port and for simultaneously controlling application of vacuum in the aspirate tubing to the aspirating port to thereby permit simultaneous dispensing a sample to the well and 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.

20. Apparatus for simultaneously dispensing and aspirating a sample to a testing device having a well, comprising:
-
a dispensing and aspirating device having a dispensing port in fluid connection with a source of a sample and an aspirating port; wherein the dispensing port and the aspirating port are configured in close proximity to each other whereby the aspirating port and dispensing port are positioned in or proximate to the well of the testing device when the dispensing and aspirating device body is positioned proximate to the testing device; and a control mechanism controlling movement of the sample through the dispensing and aspirating device enabling the sample to be simultaneously dispensed into the well via the dispense port and simultaneously aspirated the sample from the well via the aspirating port. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
