3K®-system – non-airless

The 3K®-system: the non-airless dosage system for dispensing liquid pharmaceutical or cosmetic formulations.

3K = triple protection against microbiological contamination

  1. Bacteriostatic surfaces
  2. Microbiological tight closing valve
  3. Air purifying filter

How exactly does the 3K®-system work?

Both a microbiologically tightly closing valve and the bacteriostatic effect of the surfaces used in the nozzle guarantee perfectly protected contents. In addition, the backflowing air is filtered after the pump has been actuated. Thus, the 3K®-system guarantees a perfect protection of the contents against microbiological contamination and in the meantime provides all the advantages of a multi-dosing system.

The patented 3K® pump can be combined with both plastic and glass bottles. The completely pre-assembled and sterilized pump is snapped on the sterilized primary container after the filling process, which is carried out under aseptic conditions.

Depending on the application, the 3K®-system is available with a nasal, oral and pharyngeal, ear or dermal pump. Different dosing quantities and dispension options like droplet, spray jet or spray add another layer of flexibility.
