CAPILLARY ROTATOR, an instrument for the microscopic study of small living objects (cells, protozoan eggs, etc.) in transmitted light (see figure). It is constructed in the form of a metal plate (F) fixed to the microscope stage; in its center is a circular opening (o) coinciding with the microscope illuminator. A capillary tube lies in a groove (r), rotating in the plane of the plate (F) by means of a handle (a, k). The capillary is located in the focus of the objective. The object to be studied is drawn into the capillary and, thanks to the rotation of the latter, can be examined in any position. It is manufactured by the firm Zeiss in Jena. The price is about 50 marks.
