摘要： A method for controlling a magnetic valve and particularly a method for dispensing and/or aspirating a volume of liquid as well as a corresponding dispenser/pipetting apparatus is disclosed. The method for controlling a magnetic valve has measuring a capacitance at the magnetic valve and determining a position of a plunger based on the measured capacitance. The method for dispensing or aspirating a volume of liquid has controlling a flow of a system fluid by a magnetic valve located between a pressure source and a dispenser/pipetting tip, dispensing or aspirating a volume of liquid through an exterior opening of the tip dependent on the flow of the system fluid, wherein controlling the flow and determining a flow time in dependence of the volume of liquid to be dispensed or aspirated, and controlling the magnetic valve is held open for the duration of the flow time.

摘要： A selectable volume precision liquid dispenser apparatus and method of use. The dispenser apparatus includes a graduated, segmented elastic body with an interior space having different regions corresponding to different volumes where different liquid containing chambers are separated by one-way valves. Pressure applied by a user to one of the different chambers causes the dispensing of a precise amount of liquid through an inner conducting tube having openings to receive liquid in each of the different regions, and an outlet for dispensed the liquid. Release of the pressure allows the elastic body to return towards its original (resting) shape and draw liquid from a reservoir into the previously dispensed region in preparation for the next dispensing operation.

摘要： 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.

摘要： A volume metering dispenser comprises a body having a fluid cavity therein. The body further has a body wall, at least a portion of which is transparent or translucent, thereby permitting the operator to see the level of fluid within at least a portion of the fluid cavity. A valve is disposed within the body portion, the valve comprises a seal. The seal is selectively engaged to the body in order to selectively dispense fluid. The volume metering dispenser further comprises a resilient member. The resilient member is elastically deformable and the valve is attached to the resilient member.
