Ion Wind DBD

The Ion Wind DBD uses a flat plasma electrode to create a surface dielectric barrier discharge (DBD) in the room air flowing over it. An additional “extraction” electrode is arranged in parallel to form a rectangular ventilation duct. The extraction electrode is charged, so that an additional unipolar electric field through the ventilation duct is created. This drags the ions of one polarity (either positive or negative) generated by the surface DBD in the direction of the extraction electrode.

Venturi-DBD (VDBD)

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.


Due to its high degree of flexibility, the microwave plasma source MiniMIP is suitable for various different applications and experiments. The plasma can be ignited in both pure argon and pure helium, and furthermore, an admixture of molecular gases to can be used to provide an optimal matching of the process chemistry to the requirements of the specific application.

Non-thermal atmospheric pressure plasma jet (ntAPPJ)

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.

Plasmaskop Jet

The Plasmaskop Jet has originally been designed to be inserted into the working channel of a conventional endoscope. It has a tube-like character, is flexible, very thin and generates a biologically active jet plasma at the gas outlet. The device consists of an inner plastic tube, a ceramic nozzle, an outer plastic tube and a metal wire. The inner plastic tube is plugged upon the thin end of the ceramic nozzle. In order to provide high voltage at the end of the tube and at the same time maintain tube flexibility the metal wire is coiled around the inner tube.

Ar metastable densities (³P₂) in the effluent of a filamentary atmospheric pressure plasma jet with humidified feed gas - dataset

The Ar(³P₂) metastable density in the effluent of the cold atmospheric pressure plasma jet kINPen-sci was investigated as a function of the feed gas humidity, the gas curtain composition, and the distance from the nozzle by means of laser atomic absorption spectroscopy. The data set comprises the axial distributions of the Ar metastables as a function of these parameters.

Influence of surface parameters on dielectric-barrier discharges in argon at subatmospheric pressure - dataset

The provided data describe the discharge current in DBD obtained by fluid modelling using different values of for the secondary electron emission coefficient γ and and the relative permittivity of the dielectric barrier εr in comparison with the measured current at a pressure of 100 mbar and an applied voltage amplitude of 1.8 kV. Furthermore, the dissipated power obtained by model calculations for different values of γ and εr together with the measured power in dependence on the pressure is given.
