[Circumfusion chamber for microscopic examination of living single cells and other particles]

A new circumfusion chamber is described for microscopic or micrometric investigations on living single cells and similar particles. The chamber allows to collect rare single cells. Cells are fixed within the optical field or measuring field in spite of relative high velocity of the medium. Rapid changes of the cells milieu are possible, reactions of the cell are individually visible or measureable. The chamber is temperated and allows application of different special microscopic techniques.
