[Simple flow chamber for embryos]

The chamber is made of two subject glasses arranged in such a way that nutritional medium can flow through it. In order to prevent washing out of the embryos by the stream of nutritional medium, a porous packing is inserted through which the nutritional medium is flowing. The upper subject glass has a hole through which the embryos are put into the chamber. The hole is covered with a covering glass. The chamber can be preserved for a long time "avaiting" for the cultivated material at any regime of the stream or at a static regime.
