  • the unit under c) has a check valve, in particular a check valve without metallic components, particularly preferably a check valve made of full plastic.
  • a check valve in particular a check valve without metallic components, particularly preferably a check valve made of full plastic. This ensures that when disconnecting or disconnecting the sampling system, no dripping or running of the removed chemical occurs. This is mainly from the point of view important that many of the chemicals to be removed are toxic and therefore pose a danger to anyone who comes into contact with them. Also are the high-purity chemicals are usually very expensive, which is as low as possible or does not require any loss of chemicals during removal.
  • the check valve as part of the overall adapter system as well like the entire adapter system according to the invention, preferably made of all-plastic there is no components, especially no metallic ones Components on which contamination of the chemicals to be removed could cause.
  • the check valve By turning the check valve through 180 °, the Flow direction of the liquid can be changed.

  • Means the union nut makes it possible to have a very tight, play-free connection to manufacture between the barrel and the adapter system according to the invention. Consequently no chemical and no gas can escape here during removal.
  • the union nut barrels with different dimensions connect at its output to the adapter system according to the invention, i.e. one does not need a separate adapter for removing the barrel Chemical.
  • the barrel or the barrel-shaped transport container is with a corresponding Dip tube adapter and a corresponding riser pipe, the riser pipe preferably connected to the dip tube adapter when finished, usually to the bottom of the transport container reaches in.
  • An inner section of the dip tube adapter is preferably provided with a Provide internal thread in which the one having an external thread Cap nut can engage so that the adapter system with the dip tube adapter can be reliably and sealingly connected.
  • the cap nut is loosely slidable on a cylindrical section of the adapter system arranged and an annular disc is on a cylindrical portion above of the female thread section of the union nut penetrating it and loosely arranged.
  • the union nut is preferably made of PVDF.
  • the union nut is equipped with horizontal pins for better handling.
  • Another adapter system according to the present invention comprises at least a unit to prevent the likelihood of confusion between the to be removed Chemical. It is preferably a coding system.
  • the coding system is preferably based on a pin / hole mechanism.
  • the adapter system according to the invention is by means of this pin coding system with the Dip tube adapter of the barrel lockable and by the union nut on it sealable connectable.
  • the adapter system is in its structure and its Dimensions for various different chemicals can be carried out identically with the only difference that the actual pen coding system for the respective application is to be specially trained. This makes it possible such adapter systems, which the contamination-minimized removal of a ensure special chemical, yet inexpensive to manufacture.
  • the Pen coding system preferably has coding pins and matching coding recesses on, the coding pins on a first fuse part and the coding recesses are attached to a second securing part, wherein preferably one of the securing parts is attached as an washer, which stripped secured to the preferably modular adapter system is loosely mountable and the other of the securing parts in the immersion tube adapter of the barrel is integrated.
  • the annular disc is designed as a pin disc, i.e. the coding pins are attached to it and arranged so that they are in the coding recesses provided in the immersion tube adapter, which engage accordingly the arrangement of the pins in the dip tube adapter distributed circumferentially are provided.
  • the first securing part in the form of Is formed and the second securing part in the immersion tube adapter is integrated.
  • the washer as Perforated disc is formed and the dip tube adapter corresponding pins fit into the recesses in the ring disc in a locking position, can be trained.
  • a pin coding system is therefore one Risk of confusion when connecting the adapter system to a corresponding one Transport containers excluded.
  • the coding pins as cylindrical pins and formed as circular ring segment pins, which are mirror images and conforming to the shape of the correspondingly shaped, circumferentially in the immersion tube adapter arranged coding recesses are.
  • the circular segment pins serve preferably also as a locking aid.
  • This coding system makes it very easy and quick to understand Prevents mix-ups of the chemicals during assembly.
  • connection unit of the adapter system preferably has for connecting the barrel to the dip tube adapter facing the barrel Side on a flange, which has a first O-ring for sealing the connection unit with the immersion tube adapter.
  • This O-ring is so on Flange arranged that in the tensioned state, i.e. in the state in which the union nut firmly and sealingly in the lowered internal thread section the immersion tube adapter is screwed in, the connection unit seals with the dip tube adapter is connected.
  • the adapter system in a further preferred embodiment of the adapter system according to the invention are ventilation by means of the ventilation unit and removal of the Chemical possible at the same time.
  • This can make the chemicals essential can be removed more quickly because there is no vacuum within the entire system builds up, which would make the quick removal difficult.
  • a simultaneous Ventilation is not necessary when removing within the system to build up additional pressure to remove the chemical to be removed from the barrel to bring to the removal system.
  • this is the invention Adapter system with a cylindrical tube section, which in one cylindrical part of the dip tube adapter of the barrel, which carries the riser tube, protrudes.
  • This cylindrical tube section of the adapter system according to the invention has a smaller diameter than the cylindrical part of the dip tube adapter and protrudes deeper into the cylindrical when the connection unit is installed Part of the dip tube adapter as a ventilation opening arranged therein.
