LIGHT-GUIDING ELEMENT ARRANGEMENT FOR OPTICAL DROP DETECTION
A drop-detection device detects a drop that escapes from a metering valve. The drop-detection device includes a light guide with first and second light-guiding elements that are arranged opposite each other at an intermediate space. A drop trajectory runs through the intermediate space such that a light beam sent out by the first light-guiding element crosses the drop trajectory and is subsequently coupled into the second light-guiding element. In addition, the drop-detection device includes a light-signal generation device that couples a pulsed light beam with a carrier frequency into the first light-guiding element. Furthermore, the drop-detection device also has a light evaluation device for evaluating the light beam coupled into the second light-guiding element to determine if a drop has been dispensed by the metering valve. A method of detecting a drop is also described.

Flushing device for a milk sampler
A sampler including an inlet, an outlet and a flushing device. The sampler adapted such that a sample fluid flows from the inlet, out the outlet and into sample containers. The flushing device is adapted to flush a pressurised pressurized flushing fluid past all surfaces of the sampler which are adapted to contact the sample fluid.
DOSING A FLUID AT A VOLUME OF LESS THAN ONE MILLILITER
A peristaltic dosing device for providing dosages of a fluid at a volume of less than one milliliter comprises: a flexible tube, a counter pressure element, a plurality of actors and a drive. The flexible tube is essentially straightly arranged along the counter pressure element thereby forming a longitudinal axis. The actors arranged parallel to each other along the longitudinal axis. They are moveable by the drive in relation to the flexible tube. The flexible tube is compressible between the actors and the counter pressure element by moving the actors. Each of the actors is independently and linearly moveable by the drive along an actuation axis essentially perpendicular to the longitudinal axis of the flexible tube from a home position in which the flexible tube is least compressed to an end position in which the flexible tube is compressed and sealed between the respective actor and the counter pressure element. The peristaltic dosing device according to the invention allows for exactly and repeatably providing dosages at comparably small volumes in a sterile environment.
System and apparatus for fluid sample delivery
Systems and methods for analysing a fluid are disclosed, including a fluid sample delivery apparatus. The system includes a sensing element configured to respond to at least one analyte in a sample of fluid. A detector is provided, configured to sense the response to the analyte by the sensing element. The fluid sample delivery apparatus includes a dosage needle configured to deliver the sample of fluid to the sensing element, at least one pump configured to control flow of fluid through the dosage needle, and at least one actuator configured to move the dosage needle relative to the sensing element. At least one controller is provided, configured to control the at least one pump and the at least one actuator.
DEVICE WITH FLOWMETER AND NOZZLE FOR EXACT DOSING
The present invention relates to a device with a dosing nozzle and an integrated flowmeter, which has the advantage of comprising, in a single body, a dosing nozzle for filling with products and which is equipped with an oval-gear volumetric flowmeter and a control chip for autonomous dosing. According to the invention, integrated into a single body are a main case with a cavity for accommodating the oval gears, a cavity for accommodating an electronic control chip, and a mechanically, pneumatically or electromechanically actuated dosing nozzle which is actuated by means of a pneumatic, mechanical or electromagnetic actuator, to correctly open the nozzle and control same throughout the dosing process; the oval-gear flowmeter is equipped with a permanent magnet with fields aligned with the axis of rotation and is mounted on one of the shafts of the gears to enable same to be read contactlessly, and to prevent contamination by the control chip, using an integrated circuit for detecting the rotation of the gear. A pneumatic valve of the detachable nozzle can be placed in the body to dispense with the handling of separate valves and hoses of each nozzle.

Container for dosing a flowable solid
Embodiments are directed to a container for dispensing equal doses of a flowable solid. The container may include a body defining an interior volume including a storage volume, an outlet passage, and a dosing chamber in communication with the storage volume and the outlet passage. The container may include a closure that has a lid and a plunger. The lid may be rotatably coupled to the body such that it rotates about a first axis from a closed position to an open position. The plunger may be rotatably coupled to the lid and configured to seal the dosing chamber. The container may be configured to dispense a dose of the flowable solid when the plunger is in the unsealed position and the container is at least partially inverted, and each dose may have an equal volume.
