Abstract

1392791 Multiple pipette O A SUOVANIEMI 30 Jan 1973 [10 Feb 1972 13 June 1972] 4576/73 Heading B1X A multiple pipette having inside its body a piston mover rod which is provided with a press button at its upper end and surrounded by a spiral spring which, after the rod has been pressed down, returns the rod to its, original position so that liquid is sucked into containers connected with the lower ends of the cylinders and provided with points, and which rod can be pressed down again against the spring force for discharging the liquid from containers, characterized in that, in order to reduce friction, the pistons are connected with the piston mover through a common connecting piece fixed to the piston mover or separate connecting pieces for each piston so that the pistons are able to move sideways, and that the axial movement of the pistons in relation to the piston mover is prevented by springs having a force greater than the friction force between a piston and an O-ring arranged at the lower end of each piston. The length of the stroke of the piston and thus the amount of liquid handled may be varied by means of a screened sleeve around the body of the pipette. The liquid is contained in the points of the pipette and does not enter the body.
