Abstract
A pipettor head adapter allows the adaptation of pipettors having a set number of pipettor channels to successfully pipette microtiter trays having a different number of wells than the pipettor has pipettor channels. For example, in a pipettor having 384 channels for pipetting a 384 well microtiter tray, the pipettor head adapter of the present invention will allow a “stepping down” or adaptation, such that the pipettor with its 384 pipettor channels can successfully and reliably pipette microtiter trays having 96 wells. Such adaptation occurs without the need for special microtiter trays. Industry standard operations are then preserved, even though they were previously unavailable from such a pipettor.
Claims27
An adapter for a pipettor that enables use of a number of pipette tips different than a number of pipette channels of the pipettor, the adapter comprising:
- a chassis;
- a pipette tip receiver coupled to said chassis, said pipette tip receiver adapted to engage a pipette tip;
- and
- a plurality of pipette channel engagers coupled to said chassis and adapted to engage corresponding pipette channels of the pipettor, said pipette channel engagers in communication with said pipette tip receiver;
- whereby
- a pipette tip is engageable by said pipette tip receiver and controlled by operation of said plurality of pipette channel engagers by the corresponding number of pipette channels.
An adapter for a pipettor that enables use of a number of pipette tips different than a number of pipette channels of the pipettor, the adapter comprising:
- a chassis, said chassis being generally flat and having a first side and an opposite side;
- said chassis including a pipette tip receiver having a central channel on said first side of said chassis, said pipette tip receiver adapted to engage a pipette tip;
- said chassis defining separate channels on said opposite side of said chassis adapted to engage corresponding pipette channels of the pipettor, said separate channels in communication with said central channel such that flow through said separate channels of said chassis is transmitted to said central channel of said pipette tip receiver;
- said separate channels each having an open end;
- and
- said open ends of said separate channels each being sealable such that a seal may be created between said separate channels and said corresponding pipette channels by aligned compression of the adapter against the pipettor to enable controlled flow through said corresponding pipette channels to said separate channels;
- whereby
- a pipette tip is engageable by said pipette tip receiver and flow through said central channel is controlled by flow through said separate channels caused by flow through said corresponding number of pipette channels.

- and
- a pipette channel engager coupled to said chassis and adapted to engage a corresponding pipette channel of the pipettor, said pipette channel engager in communication with each of said plurality of pipette tip receivers;
- whereby
- a plurality of corresponding pipette tips is engageable by said plurality of pipette tip receivers and controlled by operation of said pipette channel engager by the corresponding pipette channel.

- said separate channel having an open end;
- and
- said open end of said separate channel sealable such that a seal may be created between said separate channel and said corresponding pipette channel by aligned compression of the adapter against the pipettor to enable controlled flow through said corresponding pipette channel to said separate channel;
- whereby
- a plurality of pipette tips is correspondingly engageable by said plurality of pipette tip receivers and flow through said plurality of central channels is controlled by flow through said separate channel caused by flow through said corresponding pipette channel.
