Abstract

Perfection in apparatus for transferring liquid samples by means of a hollow U-shaped needle, which communicates a donor container and a receiving container, and a simple hollow needle, which ensures that the interior of the donor vessel is put under pressure, apparatus characterized by: - a fixed support, composed of first and second flat members connected by vertical uprights, - a plurality of n U-shaped needles, mounted on a third flat member and regularly distributed in a circle coaxial to the third flat member, the third flat member being located between the first and second flat members of the fixed support and guided in vertical translation by the uprights except in the upper part of these, where it can escape to effect the revolving movement around its axis, - a plurality of a maximum of N-1 troughs for cleaning or drying the U-shaped needles, arranged on the lower flat member of the fixed support and opposite each one to a U-shaped needle, - a simple needle connected to a source of compressed gas, placed near a U-shaped needle that is not facing a cleaning or drying trough and guided in vertical translation by a part of the fixed support, - a motor device that drives the third plane member in successive rotational movements with an angle of 2 π/n each, - means for driving the third flat member in vertical translation movement and - means for driving the simple needle in vertical translation movement.
