Abstract

A centrifugal chamber for coating slides with a sedimentation product of a sample fluid includes an upper part with at least one cylindrical sample chambers located therein, and a slide resting in sealed fashion against one end of the sample chambers. The slide is mounted on a flat surface of a carrier plate and is releasably connected with the assembly. The releasable connection between the upper part of the centrifugal chamber and the carrier plate which holds the slide includes a locking slide operable with one hand, with locking openings, and with the slide being displaceably mounted in the carrier plate in a longitudinal direction thereof and being further connectable with matching parts of the upper part which engage the locking openings.

Claims

1. Centrifugal chamber for coating a slide with a sedimentation product of sample fluid during a centrifuging process, the chamber including an upper part with at least one cylindrical sample chamber disposed therein, a slide abutting one end of the at least one sample chamber, a carrier plate having said slide mounted on a flat surface thereof, means for releasably connecting the carrier plate with the upper part, said means including a locking slide being provided with locking openings, means provided in said carrier plate for allowing movement of the locking slide with respect to the carrier plate, and means provided on said upper part for passing through the locking openings in and engaging the locking slide.

2. Centrifugal chamber according to claim 1, wherein the means for engaging the locking slide includes locking hooks having bent hook ends for at least partially engaging the locking slide, said hooks, in an open state, engaging the locking openings along longitudinal edges of the locking slide, and, in a closed position, gripping beneath the locking slide whereby said locking slide is displaceable in a longitudinal direction.

3. Centrifugal chamber according to claim 1 wherein the engaging means includes axially extending locking pins mounted on a bottom of the upper part, each of said pins having an annular groove of a reduced diameter, said locking openings having a substantially keyhole-shaped configuration whereby, in an open state, the respective locking pins engage a larger-diameter portion of the locking opening and, in a closed state, the annular groove engages a smaller-diameter portion of the locking opening.

4. Centrifugal chamber according to claim 1, wherein the locking slide, in an open state, projects beyond the outer dimensions of the carrier plate at least on one side thereof.

5. Centrifugal chamber according to claim 2, wherein the locking slide, in an open state, projects beyond the outer dimensions of the carrier plate at least on one side thereof.
