Abstract
1,268,790. Electro-physical measurement, particle analysis. COULTER ELECTRONICS Ltd. July 18, 1969 [July 22, 1968], No. 36340/69. Heading G1N. In a liquid sample analysis bath e.g. for a multi-aperture-tube apparatus as described in Specification 1, 232, 707. The sample supply pipe enters through the bottom of the bath (instead of the top and has a preferably catenoidal configuration to promote smooth flow of liquid into the bath.
