MULTIPURPOSE QUARTZ DISH FOR SPECTROPHOTOMETRIC MEASUREMENTS UNDER PRESSURE ( VERSIONS )

摘要

measurement technology. SUBSTANCE: there are proposed two versions of design of multifunctional quartz dish which combines functions of traditional spectrometric dishes for work under excessive pressure and makes it possible to separate two solutions of reagents, to mix them at any time determined by operator in addition. In agreement with first version all-quartz dish is made of rectangular optical part, quartz rod with 1.0 mm capillary, cylinder and cylindrical plug. According to second version split dish with microsection is separated from upper cylinder by location plug with 0.02 mm capillary. Capillary hole in dish of first type is diminished by inserted rod after filling with first solution. Solution in cylinder is separated from solution in dish and can be injected into volume of optical part of dish after rise of pressure only. EFFECT: design of proposed dish makes it feasible to conduct several subsequent injections with rise of pressure. 9 cl, 2 dwg
