The attomol® Caleidoscan 100 (CS100) is an automated fluorescence measuring device which is used for imaging recording of fluorescent micro objects, e.g. fluorescence and size coded micro particles (beads) when measuring attomol® Beadassays . The CS100 is controlled by the control and evaluation software attomol® Caleidopro (CP). Compared to flow cytometric measurement methods the CS100 is much faster.
