Dispenser

Dispenser according to one of the preceding claims, wherein the conveying element is a pump, preferably a diaphragm pump.

Dispenser according to one of the preceding claims, wherein the conveying element.is connected to the storage element by means of a second line.

Dispenser according to one of the preceding claims, wherein the closure device is a solenoid.

Dispenser according to one of the preceding claims, wherein the device for regulating the pressure of the liquid in the first line comprises a third line which branches off the first line, as well as a pressure valve for opening and closing the third line, and the third line opens into the storage element and/or the second line in front of the conveying element in the direction of travel.

Dispenser according to one of the preceding claims wherein the pressure of the liquid in the region between the conveying element and the closure device is regulated, by means of the device for regulating the pressure, so as not to exceed a threshold value.

Dispenser according to one of the preceding claims, wherein a dispensing element with at least one inlet opening and at least one outlet opening is provided on the end of the first line downstream of the conveying element.

Dispenser according to one of the preceding claims, wherein the direction of conveying of the conveying element is reversible.

Dispenser according to one of the preceding claims, wherein the opening and closing cycle of the rapid closing device can be controlled by a microprocessor.

Dispenser according to one of the preceding claims, wherein the first line and/or the second line and/or the third line is/are made from a plastic which is easily bendable.

Dispenser according to one of the preceding claims, wherein one or more collecting containers into which the metered liquid is dispensed is or are provided at the outlet from the first line and/or the dispensing element.

Dispensing element, particularly for use in a dispenser according to one of the preceding claims,

• having an inlet opening and at least two outlet openings,
• a first and a second transverse channel for distributing the liquid which is to be dispensed, and
• at least two supply channels between the first and second transverse channels.

Dispensing element according to one of claims 21 to 29, wherein the transverse channels are connected by additional flushing channels.

Process for the substantially automated, finely metered dispensing of liquids, preferably reagents, comprising the following steps:

• a) sucking the liquid out of a storage element into a pipe system;
• b) building up a pressure in the liquid which is substantially constant over time in at least one section of the pipe system,
• c) metering the quantity of liquid to be dispensed by briefly opening a rapid-acting closure device arranged in the pipe system, so that a quantity of liquid corresponding to the duration of opening of the rapid-acting closure device and the liquid pressure is dispensed from the section of the pipe system.
