A device is described that overlays a first fluid, such as blood or a cellular suspension onto a base material, such as a density gradient. In some embodiments, the fluid layering device includes a cylindrical reservoir, a fluid barrier, a coupling extension, a plunger, and an exhaust vent. The fluid layering device can be coupled through its coupling extension to an open end of a container, such as a conical centrifuge tube, including the density gradient. Once attached, the plunger may be lowered to a position above the surface of the density gradient. A first fluid may flow from the reservoir into the conical tube across the plunger, so that a suitable overlay is formed without substantially disturbing a surface of the density gradient.

In some instances, an apparatus can include a light sensitive imaging sensor having a surface to receive a fluid sample, a body to be moved relative to the light sensitive imaging sensor and having a surface to touch a portion of the fluid sample, and a carrier to move the body toward the surface of the light sensitive imaging sensor to cause the surface of the body to touch the portion of the fluid sample, so that as the surface of the body touches the portion of the fluid, the surface of the body (i) is parallel to the surface of the light sensitive imaging sensor, and (ii) settles on top of the fluid sample independently of motion of the carrier.

Aspects of the present disclosure are directed to a device for carrying out heterogeneous immunoassays by means of magnetic particles in cuvettes lined up next to one another, wherein each cuvette has a filling opening and at least one lateral measurement window which is transparent to the measurement radiation.
