Abstract

A lab member for use in a laboratory liquid handling system including a pipetting module and a drive system, the pipetting module including first and second pipettors, the first and second pipettors including first and second pipettor shafts, respectively, a first pipetting tip extending from an end of the first pipettor shaft, and a second pipetting tip extending from an end of the second pipettor shaft, includes a lab object and first and second integral adapter structures. The first and second adapter structures are configured to engage the first and second pipettor shafts, respectively. The first adapter structure is configured to releasably secure the lab member to the first pipettor shaft.

First claim

What is claimed is:

1. A laboratory liquid handling system comprising:
a pipetting module including a pipettor including a pipettor shaft and a pipetting tip extending from an end of the pipettor shaft;
a lab member including:
an electronics module; and
an integral adapter structure, wherein the integral adapter structure is configured to releasably secure the lab member to the pipettor shaft; and

a drive system including a motor and a controller operative to control the motor, wherein the drive system includes a controller programmed to:
selectively engage the pipettor shaft with the integral adapter structure to secure the lab member to the pipetting module;
move the pipetting module to transport the lab member secured to the pipetting module; and
selectively disengage the pipettor shaft from the integral adapter structure to thereby release the lab member from the pipetting module.

2. The laboratory liquid handling system of claim 1 wherein the electronics module includes a transducer.

3. The laboratory liquid handling system of claim 2 wherein the electronics module includes a housing holding the transducer.

4. The laboratory liquid handling system of claim 1 wherein the electronics module includes an onboard controller.

5. The laboratory liquid handling system of claim 1 wherein the electronics module includes a sensor.

6. The laboratory liquid handling system of claim 5 wherein the sensor is an ultrasonic sensor.

7. The laboratory liquid handling system of claim 5 wherein the sensor is an optical sensor.

8. The laboratory liquid handling system of claim 5 wherein the sensor is a temperature sensor.

9. The laboratory liquid handling system of claim 1 wherein the lab member is includes an electrically conductive material to transmit power and/or communications signals through the integral adapter structure to and/or from the electronics module.

10. The laboratory liquid handling system of claim 9 wherein the integral adapter structure includes an electrical contact portion to engage and electrically couple the electrically conductive material with a portion of the pipettor when the pipettor is inserted into the integral adapter structure.

11. The laboratory liquid handling system of claim 10 wherein the integral adapter structure includes an electrically conductive sleeve configured to receive the pipettor and provide electrical continuity between the pipettor and the electronics module.

12. The laboratory liquid handling system of claim 1 wherein the lab member further includes a second integral adapter structure configured to engage a second pipettor shaft of the pipetting module.

13. The laboratory liquid handling system of claim 1 wherein the integral adapter structure includes a socket configured to receive the pipetting tip and an adjacent lower section of the pipettor shaft such that the lower section is releasably captured in the socket.

14. A method for transporting a lab member using a laboratory liquid handling system including a pipetting module and a drive system, the pipetting module including a pipettor including a pipettor shaft and a pipetting tip extending from an end of the pipettor shaft, the method comprising:
providing a lab member including:
an electronics module; and
an integral adapter structure, wherein the integral adapter structure is configured to releasably secure the lab member to the pipettor shaft;

using the drive system, selectively engaging the pipettor shaft with the adapter structure to secure the lab member to the pipetting module;
using the drive system, moving the pipetting module to transport the lab member secured to the pipetting module; and
using the drive system, selectively disengaging the pipettor shaft from the integral adapter structure to thereby release the lab member from the pipetting module.

15. The method of claim 14 wherein:
the electronics module includes a sensor; and
the method further includes acquiring data from a selected location using the sensor coupled to the pipettor shaft.

16. The method of claim 15 further including:
using the sensor, sensing an attribute at the selected location and generating and sending a corresponding data signal to a controller; and
using the controller, programmatically determining a next action based on the data signal.

17. The method of claim 14 further including transmitting power through the integral adapter structure to and/or from the electronics module.

18. The method of claim 14 further including transmitting communications signals through the integral adapter structure to and/or from the electronics module.

19. The method of claim 14 wherein the electronics module includes a transducer.

20. The method of claim 19 wherein the electronics module includes:
a housing holding the transducer; and
an onboard controller.

21. The method of claim 14 wherein:
the lab member further includes a second integral adapter structure configured to engage a second pipettor shaft of the pipetting module; and
the method includes:
using the drive system, selectively engaging the second pipettor shaft with the second adapter structure td secure the lab member to the pipetting module; and
using the drive system, selectively disengaging the second pipettor shaft from the second integral adapter structure to thereby release the lab member from the pipetting module.

22. The method of claim 14 wherein:
the integral adapter structure includes a socket; and
the step of selectively engaging the pipettor shaft with the adapter structure includes inserting the pipetting tip and an adjacent lower section of the pipettor shaft into the socket such that the lower section is releasably captured in the socket.
