Embodiment Construction

[0022] The invention will now be described with reference to illustrative examples. It will be apparent that a multi-channel exhaust pipette according to the invention may be implemented in various forms. Therefore, the specific structural and functional details disclosed herein are representative and do not limit the scope of the invention.

[0023] First refer to figure 1 , shows an overview diagram of a hand-held multi-channel pipette 110 according to the present invention.

[0024] The pipette 110 includes a hand-held body 112 containing a volume adjustment mechanism and a plunger button 114 axially movable toward the body. In the illustrated pipette 110, as the plunger button is operated by applying pressure to the plunger button, this movement is transferred through the plunger rod 116 (mostly inside the body) to the liquid end assembly 120. In the disclosed embodiment, the liquid end assembly 120 includes a relatively low profile housing 122 .

[0025] Housing 122 i...

Abstract

A handheld multichannel air displacement pipette is modular in construction and includes compliant joints and molded plastic components in place of various machined metal, glass, and ceramic components found in traditional multichannel pipettes. These improvements are made without sacrificing performance in channel-to-channel consistency, accuracy, and precision. The multichannel pipette is inexpensive to manufacture, lightweight, reliable, and easy to assemble and service.

Description

technical field [0001] The present invention relates to liquid handling pipettes, and more particularly to hand-held multi-channel exhaust pipettes operable to simultaneously measure and transfer a plurality of substantially identical small volumes of liquid. Background technique [0002] Hand-held multi-channel exhaust pipettes are well known and have been commonplace in laboratory settings for decades. Such pipettes are particularly useful for quick and easy transfer of liquid samples, eg, between microtubes and multiwell plates. Typically, multichannel pipettes have a plurality of nozzles arranged in one or more evenly spaced rows, and the nozzles are configured to receive disposable pipette tips similar or identical to those used on single channel hand-held pipettes. For an example of a conventional multichannel pipette configuration, see US Patent No. 4,779,467, which is hereby incorporated by reference as if fully set forth. [0003] Ergonomic considerations are impo...
