Abstract:
1. Apparatus for measuring a plurality of optically detectable beads, said apparatus comprising a) a vacuum container comprising at least one planar capture body capable of rotating around a central axis, wherein said capture body comprises a plurality of through- going inlets, wherein the diameter of each inlet is smaller than the average diameter of the beads to be measured and/or analysed and/or sorted, b) a pressure controlling device capable of controlling the pressure in the vacuum container, and c) a device for rotating the vacuum container around the axis of the capture body d) a device for measuring at least one property of at least one bead the apparatus further comprising a capture body support supporting the capture body at a distal end and being connected at a proximal end to a hollow shaft, wherein the hollow shaft is fitted with a shaft opening so that a vacuum can be applied to the interior of the vacuum container, and a vacuum container housing comprising an outer cylinder comprising an opening for connecting the shaft hole with the pressure controlling device, and a guiding plate comprising at least one opening allowing the through-going inlets to be accessible to beads to be loaded onto the capture body, said guiding plate being attached to the top part of the outer cylinder, thereby defining in the space between the guiding plate and the capture body a guiding channel for harbouring beads, said guiding plate confining the vacuum container to the interior of the vacuum container housing.
