SYSTEMS AND METHODS FOR AUTOMATIC PLATE WASHING
First Claim
1. An automated system for washing multiwell plates, the system comprising:
- an arm having a metal portion and having a multiwell plate holder for holding a multiwell plate;
a first rotational servo configured to rotate the multiwell plate about a first axis;
a second rotational servo configured to rotate the arm about a second axis; and
a controller configured to;
operate the first rotational servo as a first closed loop servo to rotate the multiwell plate about the first axis from an upward position to a downward position;
operate the second rotational servo as a second closed loop servo to rotate the arm about the second axis such that the metal portion moves towards a first electromagnet and to transition the second rotational servo to operating as an open loop servo; and
activate the first electromagnet to cause the first electromagnet to pull the metal portion towards the first electromagnet while the second rotational servo operates as the open loop servo, wherein a deceleration impulse caused by the arm contacting a first stop dispels fluid in the multiwell plate.

Abstract
The present disclosure relates to automated systems and methods for washing microtiter plates that offer advantages such as increased efficiency and decreased contamination during the washing process. In an exemplary embodiment, an automated system for washing multiwell plates comprises an arm having a metal portion and having a multiwell plate holder for holding a multiwell plate; a first rotational servo configured to rotate the multiwell plate about a first axis; a second rotational servo configured to rotate the arm about a second axis; and a controller configured to operate the system to dispels fluid in the multiwell plate.
