Pipette block with molded piston chambers

Abstract

The present invention relates to a pipette dispensing block with an improved design for the piston chambers. In a multichannel pipetting block with a grid or array of pipetting piston of any order, the individual piston chambers are individually manufactured using the injection molding process. The individual piston chambers are assembled into a grid or single line array and held together by upper and lower plates in combination with either stabilizing posts or walls. The piston chambers are designed and assembled with a dual o-ring design at the tip and a tip sealing gasket at the bottom to provide the air-tight seal that is required for optimum pipetting performance. When combined with pistons and a motor-driven lifting plate for the pistons, the entire assembly forms a forms a multichannel pipetting block
