Abstract

1276105 Automatic analysis COULTER ELECTRONICS Inc 6 Oct 1969 [10 Oct 1968] 48991/69 Heading B1X [Also in Divisions G1 and G2] Apparatus for dispensing diluent from reservoir 20 into cuvette 50 for measurement comprises spring-loaded piston 32 moving in cylinder 28, one end of the cylinder being connectable to atmosphere through normally closed valve V1B and the other end being connected to liners 22, 26 as shown. When the sample in the cuvette has been measured, valve V3 is opened under control of programming device 72 and the sample is tucked away by pump 46. Valve V3 is closed, valve VIA is closed and valve V1B opened to produce atmospheric pressure in line 36. Piston 32 then moves to force diluent already in line 26 into the cuvette.
