A fluid delivery system has a container with an integrally attached sample cell. A selected fluid can be accumulated in the container. The sample cell can be filled with part of the fluid in the container and then isolated from the container by heat or dielectric sealing. The fluid in the sample cell can be brought into contact with selected test reagents. The test reagents can provide a visual indicia of the presence of selected characteristics in the fluid.

A reservoir for blood or the like in which a rigid casing, having a perforated tubular member positioned within the casing and extending between the ends thereof, carries filtering and blood defoaming means. An improved configuration of inlet aperture means is provided. Also, the reservoir may define an upstanding central hump at its lower end, surrounded by an annular trough positioned at an acute angle to the axis of the perforated tubular member, for improved recovery of blood from the reservoir and improved calibration of the amount of blood in the reservoir.
