Sampling device for taking beverage samples from a beverage line containing a pressurized carbonated beverage, wherein the sampling device has - a connection for the beverage line, - a pump having a drive, which pump has a pump chamber that is delimited by walls (16, 17) that can be moved towards and away from one another, in order to expand and compress the pump chamber by means of the drive, - a discharge opening for the beverage sample, - a particulate filter with an inlet and an outlet for the beverage sample, for filtering the beverage sample, - a line system with adjustable valves, which is connected to the connection for the beverage line, the pump chamber, the discharge opening, the inlet of the particulate filter, the outlet of the particulate filter, a supply line for a backflushing medium and a waste outlet opening, and - a control device, and wherein the line system is configured in such a manner and the control device is in control connection with the pump and the valves in such a manner i) that in a first valve configuration, in which the pump chamber is connected to the connection for the beverage line and is separated from the outlet opening, the supply line for the backflushing medium and the discharge opening, a beverage sample, the volume of which is smaller than the maximum volume of the pump chamber, can be introduced into the pump chamber from the connection for the beverage line, ii) that thereafter a second valve configuration is set, in which the pump chamber is separated from the connection for the beverage line, from the outlet opening, the supply line for the backflushing medium and the discharge opening, and the pump chamber is expanded in such a manner that a vacuum is created in the pump chamber, in order to degas the beverage sample, iii) that thereafter a third valve configuration is set, in which the pump chamber is connected to the outlet opening and is separated from the connection for the beverage line, the supply line for the backflushing medium and the discharge opening, and the pump chamber is compressed in such a manner that a first partial volume located in an upper part of the pump chamber is displaced towards the outlet opening and a second partial volume located in a lower part of the pump chamber remains in the pump chamber, iv) that thereafter a fourth valve configuration is set, in which the pump chamber is connected to the discharge opening via the particulate filter and is separated from the connection for the beverage line, the supply line for the backflushing medium and the outlet opening, and the pump chamber is further compressed to displace the sample located therein towards the discharge opening. v) that thereafter a fifth valve configuration is set, in order to backflush the particulate filter, in which configuration the supply line for the backflushing medium is connected to the outlet opening via the particulate filter. -
