Photometric cell for liquids analysis - allows emptying, cleaning and refilling without carry-over of liquid

Abstract

Abstract Photometric cell or multicell, which holds a liq. to be analysed and through which a light beam passes, consists of a tube, constituting the cell itself, bounded at its ends by two plane parallel dioptres which are the entry and exit of the light beam. The angle between the tube and the dioptres is other than 90 degrees. At each end of the tube another tube is connected, one for suction or cleaning liq. entry, the other for charging the liq. to be analysed. These tubes are connected into the sides of the cell tube, on opposite sides and extending in opposite directions and they make with the latter an angle other than 90 degrees. The absence of acute or right angles in the liq. path allows emptying, washing and refilling to be carried out without carry-over of liq. from one operation to the next. Cells can be obtd. with well defined optical paths, capable of being grouped to form a multicell with automatic filling and emptying.
