Abstract:
Provided is a method for removing a liquid, in particular a supernatant, from a container with a sample, by creating an opening in a container with a sample consisting of solid constituents and a liquid, and subsequently centrifuging the container so as to cause the liquid to flow out of the container through the created opening. Also provided is a device for making a container suitable for use in the method.
Abstract:
A turret assembly for receiving and holding lengths of re-cut tubing cut or sheared from a longer-length workpiece by a re-cut device. The turret assembly includes a motor, a plate and a plurality of accumulator members. The accumulator members are supported by the plate in essentially parallel, spaced-apart relationship to receive a predetermined quantity of lengths of re-cut tubing from the re-cut device. The plate is rotated by the motor. A stripping device having a stripping collar and a linear actuator can strip tubing from the accumulator members. A stacking element can collect stripped tubing from the accumulator members and stack tubing in a container.

Abstract:
APPARATUS FOR MAKING PERFORATIONS IN HELICALLY OR CIRCUMFERENTIALLY CORRUGATED PLASTIC TUBES COMPRISES FLAT PLATE-LIKE PERFORATING TOOLS WHICH ARE MOVABLE RADIALLY TOWARD AND AWAY FROM THE TUBE, A FEEDING MECHANISM WHICH ADVANCES THE TUBE, EITHER STEPWISE OR CONTINUOUSLY, AND DRIVEN CARRIERS WHICH SUPPORT THE TOOLS AND ARE MOVABLE RADIALLY OF THE TUBE OR IN PLANES WHICH INCLUDE THE
AXIS OF THE TUBE. EACH TOOL HAS A CUTTING EDGE WHICH IS FLANKED BY RECEDING SURFACES AT BOTH SIDES AND IS PROVIDED WITH PRONOUNCED TEETH HAVING TIPS LOCATED AT THE SAME LEVEL OR AT DIFFERENT LEVELS.
