The kINPen® MED is a member of the kINPen® family certified as a class IIa medical device. In medical practice, the kINPen® MED is primarily used for treating chronic wounds and pathogen-induced skin diseases. One of the key features allowing the certification as a medical device is the low gas temperature of typically 35...38 °C. A vast number of publications investigating the kINPen® MED is available, the section below presents only selected examples.

The device is commercially available from neoplas med GmbH.

The gas pressure is an effective parameter to control plasma-chemical reactions, but its adjustment often requires substantial effort. In the Venturi-DBD (VDBD), the pressure can be set to any value between 100 mbar and 1000 mbar reliably and reproducibly. Using a Venturi pump for vacuum generation ensures that the system is affordable and almost maintenance-free. With air as process gas, the output gas composition can seamlessly be adjusted from a strongly ozone-dominated regime to a nitrogen oxides-only-regime including nitric oxide.

Plasma as a cross-sectional technology in many industry branches, but also in research laboratories, is an indispensable tool in surface treatment. Plasma technology is used everywhere where quality, productivity, environmental sustainability, precision and flexibility is important. Surfaces are cleaned, activated and decontaminated at atmospheric pressure with the handy kINPen® IND. The device is particularly used for surface treatment of temperature-sensitive materials as, for instance, plastics.

The non-thermal atmospheric pressure plasma jet (ntAPPJ) is composed of a quartz capillary with an inner diameter of 4 mm and an outer diameter of 6 mm. The plasma jet operates at a high frequency of 27.12 MHz in pure noble gases (helium, neon, argon, krypton) at flow rates between 0.1 and 2 slm. Small molecular gas admixtures or organic vapors can be added to the carrier gas. Two outer ring electrodes (width 5 mm, distance 5 mm) are adjusted concentrically with the capillary axis.

The HelixJet is a capacitively coupled radio-frequency (RF) plasma source operating at atmospheric pressure. The RF power is applied to two double helix electrodes. The electrodes are placed outside a quartz tube fed by the working gas. The HelixJet has unique features highly relevant for practical applications. The innovative double helix electrode design enables extremely stable and homogeneous plasma conditions at low gas flow rates. This plays a crucial role for the quality and reproducibility of several applications, e.g.
