Abstract
Methods and apparatus to reduce biological carryover using induction heating are disclosed herein. An example method includes washing an aspiration and dispense device. The example method includes generating an alternating electromagnetic field and introducing the aspiration and dispense device into the alternating electromagnetic field. The example method includes inductively heating the aspiration and dispense device with the alternating electromagnetic field. In the example method, the washing is to occur in concert with the heating.
Claims21
A method comprising:
- washing an aspiration and dispense device having a first portion and a second portion;
- generating an alternating electromagnetic field by causing a current to flow through an electrically conducting media;
- introducing the first portion and not the second portion of the aspiration and dispense device into the alternating electromagnetic field;
- detecting a change in the current based on a load change with respect to the electrically conducting media, the load change associated with the introduction of the first portion of the aspiration and dispense device into the alternating electromagnetic field;
- inductively heating the first portion of the aspiration and dispense device with the alternating electromagnetic field, the washing to occur in concert with the heating;
- introducing the second portion of the aspiration and dispense device into the alternating electromagnetic field;
- adjusting a frequency of the alternating electromagnetic field in response to the introduction of the second portion in the alternating electromagnetic field;
- and
- inductively heating the second portion of the aspiration and dispense device with the adjusted alternating electromagnetic field.
