Complete emptying

Custom-made AS QC-dip tubes with or without bellow enable a best possible complete drainage.
Adapted to various lengths and threads, they ensure virtually complete drainage even from large containers.

High-purity plastics

For example, HDPE, PVDF and PFA – also available in a conductive version for hazardous areas.
Always completely made of plastic and thus protected against corrosion.
Especially developed variants made from stainless steel for the pharmaceutical industry complete the portfolio.

Suitable for all containers

For 5 to 1000 litre container and packaging systems.
QC is the right solution for IBCs, drums or canisters, for every connecting thread metric or buttress thread. And it can empty every format more efficiently than you've ever seen before.

Overview container Overview dip tubes

Ventilation of the container

The integrated ventilation channels in the dip tube and the Dispense Head ensure safe ventilation of the container during emptying. They also prevent any potential overpressure in the container from escaping uncontrollably when the dip tube closure is opened, as it can for example happen with alternative dip tubes.



In the QC2 and G-Series product line, chemicals can be recirculated / filled back into the container through a second dip tube and fill head, which are mounted to the second drum opening.


Closures and tamper proof closures

A variety of closures and matching tamper-proof closures protect the medium during transport.
Also available in versions with built-in ventilation for media such as hydrogen peroxide.
