Abstract
A housing retains an essentially disk-like center element made of light-tsmissive material, or formed with an opening therein, and shaped to receive a capillary tube (or formed with a capillary opening itself) extending radially transversely to the disk-shaped element, essentially half-way in the thickness thereof, the central element being bounded on at least one side by window-like diaphragm elements, either separate parts or incorporated on the central part to define a light path through the capillary tube to permit centrifuging and optical investigation of minute quantities of substances to be tested by centrifuging, for example blood sera to determine sedimentation.
Claims19
Analytic cell for use in a centrifuge, particularly an ultra high-speed centrifuge comprising
- a housing (10);
- a disk-shaped central part (15, 30) located in the housing and formed with a radially extending light-transmissive slit across the part (24, 24', 26, 26', 29), the central part being further formed with a radially extending opening extending in alignment with the light-transmissive slit and of sufficient size to permit introduction of a capillary tube therein;
- and a capillary tube of light-transmissive material located in said opening and for optical evaluation of test substances within the capillary tube located in alignment with said slit.
