MULTIPLE PIPETTE SAMPLER ABSTRACT OF THE DISCLOSURE A pipette sampling device for removing and transferring a plurality of liquid samples consists of an improved structure which allows a low cost manufacturing process, the use of a minimum amount of material in such process, and a pipette cavity shaped such that hydraulic principles insure accuracy during filling and dispensing. The pipette sampling device is positionable within a filling tray which permits an initial filling of the pipettes by a liquid through capillary action, and an actuating device is then attached over the pipettes. The actuating device provides a vacuum so that the liquid is drawn into each pipette cavity until the walls and rims of all of the cavities are completely wetted and a stretched meniscus is formed at the top of each cavity. The actuator may then be utilized to effects the dispensing of the liquid in each pipette cavity through a provided pressure. To accomplish this process, the sampling device is constructed to include a manifold which is designed as an inflexible, rigid monocoque structure.
