Abstract
A liquid handling system and method includes a liquid handling device with a plurality of pipetting heads and a tip box having a plurality of tips for removable attachment to the pipetting heads. A lever mechanism engages the liquid handling device and tip box during insertion of the pipetting heads into the tips to lesser the required insertion force.
Claims18
A liquid handling system, comprising:
- a liquid handling device having a plurality of pipetting heads;
- a tip box having a plurality of tips configured for removable attachment to the pipetting heads;
- and
- a lever mechanism configured to engage the liquid handling device and the tip box during a process of moving the liquid handling device along a central axis in the direction of the tip box for attachment of the tips to the pipetting heads, the lever mechanism including:
- a first lever arm attached to a first fulcrum proximate the central axis, extending outwardly from the central axis, and terminating in a first arm end;
- and
- a second lever arm attached to a second fulcrum proximate the central axis, extending outwardly from the central axis, and terminating in a second arm end,
- wherein the lever mechanism is configured to receive a force from the liquid handling device proximate the first fulcrum and the second fulcrum, the first lever arm and second lever arm applying an opposite force to urge the tip box and liquid handling device together.

A method for connecting components during liquid handling, comprising:
- providing a liquid handling device having a plurality of pipetting heads;
- providing a tip box having a plurality of tips configured for removable attachment to the pipetting heads;
- aligning the liquid handling device and the tip box along a central axis;
- positioning a lever mechanism along the central axis to engage the liquid handling device and the tip box during a processing of moving the liquid handling device along the central axis in the direction of the tip box for attachment of the tips to the pipetting heads, the lever mechanism including:
- a first lever arm attached to a first fulcrum positioned proximate the central axis, extending outwardly from the central axis, and terminating in a first arm end;
- and a second lever arm attached to a second fulcrum positioned proximate the central axis, extending outwardly from the central axis, and terminating in a second arm end;
- and
- attaching the tips to the pipetting heads by moving the liquid handling device along the central axis to apply a force proximate the first fulcrum and the second fulcrum such that the first lever arm and second lever arm apply an opposite force to urge the tip box and liquid handling device together.
