Abstract
1433414 Cuvette layout LABTRONIC AG GES FUR KLINISCHE LABORTECHNIK 24 April 1973 [25 April 1972] 19231/73 Heading J In a cuvette layout for receiving liquid samples for photometric measuring of absorption, the cuvette has a vacuum line connected at the top to a sample holding space through the bottom of which light 30 passes, Fig. 3, a sample delivery line 22 having an oblique outlet 27 which is just below the level of the liquid sample and vertically opposite an incline 29 and a cuvette emptying suction line 23 connected at the bottom to the sample space. In the layout, the application of a vessel 1, Fig. 1 containing the liquid sample to a sample delivery suction tube 19, carried on a member pivoted at 4 actuates a switch 5 which opens valve 9 in a vacuum line 18 containing a choke 10, closes valve 11 in a cuvette-emptying suction line 20 and starts pump 6 whereby vacuum draws a quantity of the liquid along lines 3, 19, 22 into the cuvette 13 until the level 7 of a light barrier 8 is attained whereby the pump is switched off.
