Abstract
This invention relates to methods, systems, and computer program products for detecting pipette tip integrity.
Claims16
A computer system, comprising:
- a processor;
- and
- a memory coupled to the processor, the memory comprising computer readable program code embodied therein that, when executed by the processor, causes the processor to perform operations comprising:
- collecting pressure data while a gas is aspirated into a pipette tip attached to a pipette, the pressure data including a plurality of pressure values measured at an internal portion of the pipette and taken over a given time interval, the plurality of pressure values including a maximum pressure value and a minimum pressure value;
- estimating a pressure range value between the maximum pressure value and the minimum pressure value while the gas is aspirated into the pipette tip attached to the pipette;
- responsive to the pressure range value being greater than or equal to a lower threshold and the pressure range value being less than or equal to an upper threshold, determining that the pipette tip attached to the pipette is properly functioning, or
- responsive to the pressure range value being less than a lower threshold or the pressure range value being greater than an upper threshold, determining that the pipette tip attached to the pipette is not properly functioning;
- and
- responsive to the pressure range value being greater than or equal to the lower threshold and the pressure range value being less than or equal to the upper threshold, determining that the pipette tip attached to the pipette is suitable for use, or
- responsive to the pressure range value being less than the lower threshold or the pressure range value being greater than the upper threshold, determining that the pipette tip is defective, clogged, and/or improperly attached to the pipette.

A computer program product comprising:
- a non-transitory computer readable storage medium having computer readable code embodied in the medium, the computer readable code comprising:
- computer readable code that, when executed by a processor, causes the processor to perform operations comprising:
- collecting pressure data while a gas is aspirated into a pipette tip attached to a pipette, the pressure data including a plurality of pressure values measured at an internal portion of the pipette and taken over a given time interval, the plurality of pressure values including a maximum pressure value and a minimum pressure value;
- estimating a pressure range value between the maximum pressure value and the minimum pressure value;
- responsive to the pressure range value being greater than or equal to a lower threshold and the pressure range value being less than or equal to an upper threshold, determining that the pipette tip attached to the pipette is properly functioning, or
- responsive to the pressure range value being less than a lower threshold or the pressure range value being greater than an upper threshold, determining that the pipette tip attached to the pipette is not properly functioning;
- and
- responsive to the pressure range value being greater than or equal to the lower threshold and the pressure range value being less than or equal to the upper threshold, determining that the pipette tip attached to the pipette is suitable for use, or
- responsive to the pressure range value being less than the lower threshold or the pressure range value being greater than the upper threshold, determining that the pipette tip is defective, clogged, and/or improperly attached to the pipette.
