The present disclosure relates to a container for the production of a foamed sclerosant composition, to kits and systems including such a container, to methods for preparing a foamed sclerosant composition using such containers, and to a foamed sclerosant compositions obtainable by such methods. In an aspect, the container comprises a container body and a mixing element disposed in the container body, such that a foaming space is defined in an interior of the container body between the sidewalls and the mixing element. The mixing element may be configured to be operatively coupled with a rotating actuator without the actuator reaching the foaming space.

The invention relates to a conveyor system for conveying at least one material to be conveyed, comprising a continuously circulating conveyor, at least one transponder, preferably an RFID transponder, arranged on or in the conveyor, and at least one communication device for wirelessly transmitting data to the transponder and/or for wirelessly reading data saved in the transponder, said conveyor being a pocket conveyor belt. The conveyor preferably comprises a plurality of transponders arranged at regular intervals, wherein the data transmitted to the individual transponders or the data saved in the individual transponders preferably relates to information about a defined section of the conveyor, such as information relating to the type and/or amount of the material to be conveyed in a section of the conveyor assigned to the respective transponder.

We disclose an apparatus (2) for supplying a particulate material (4) at a target mass flow rate, the apparatus comprising an entrainment region (6) configured to entrain the particulate material (4) in a gas or gas mixture flowing through the entrainment region (6), a cross-sectional area of at least a part of the entrainment region being adjustable based on the particulate material (4) and a supply device (8) configured to supply the particulate material (4) to the entrainment region (6) at approximately or at the target mass flow rate.
