1,150,548. Photometers. CESKOSLOVENSKA AKADEMIE VED. May 26, 1966 [May 27, 1965], No.23636/66. Heading G1P. A through flow measuring cell for photometers comprising a body member 1, Fig.1, having a bore 2 extending therethrough and closed at each end by a window 3, 3', and seals, 4, 4', there being an inlet 8, and outlet 9 for the sample liquid, has the inlet 8 terminating in the bore 2 with a reduced cross-section so that the resultant increased flow velocity produces turbulence in the supplied liquids. As shown the end forces of the body member 1 have tapered grooves entering the bore 2 tangentially at their narrowed ends and communicating with inlet 8 and outlet 9 respectively at their other ends. Alternatively the tapered grooves may be formed in the seals 4, 4'. |
