Nebula - Low Pressure Plasma Treatment
The Henniker Plasma 'NEBULA' range of low pressure plasma treatment systems are standalone systems with large capacity chambers for treating larger format parts, or more parts in a single batch. They are suited to both regular industrial usage and also for development of new processes and surface chemistry. NEBULA plasma treatment systems have a large HMI interface and are controlled via an industrial PLC system. They allow user level access ranging from simple operator, able to execute programs only, to full administrator, able to create users, edit and test new recipes. Due to their flexibility and robustness, they are chosen where reliability and flexibility are paramount.
Each NEBULA system can be configured with a variety of options including horizontal and vertical sample loading and also a rotary drum for treating many small parts or even powders. The user can specify up to three gas inlets as well as a precise monomer dosing inlet for plasma polymerisation work. In this way, simple cleaning and activation tasks can be extended to produce permanent polymeric coatings on many surfaces.

Surface Testing Equipment
Easy test dyne pens
Easy test Dyne pens allow rapid assessment of surface energy. Surface energy is the property of a surface arising from unbalanced molecular forces at or near the surface, compared to those in the bulk material, and provides a quick indication of adhesion characteristics and wettability.
If a liquid is applied to the surface and its surface energy is higher than the surface energy of a material to which it is applied then the liquid tends to form droplets. If the surface energy of the liquid is lower than that of the surface to which it is applied it will spread out or “wet” the surface evenly. This is the basis of the Dyne test.
The pens are filled with Dyne test fluids of various values, from 28mN/m to 105mN/m surface tension. The pen is drawn across a plasma treated surface and if the liquid draws together or forms beads on the surface then the surface energy is less than the Dyne level of the pen, indicating that the plasma treatment has not been performed.
Easy Test Dyne Pens are available off the shelf for next day delivery.
Portable Contact Angle Meter
The PGx is a fully automated Portable Contact Angle Meter that measures surface wetting and absorption in-situ on virtually any size or shape of surface.
With a footprint of only 90mm x 55mm and weighing just 400g, it is the smallest contact angle meter available, with features previously found only in larger laboratory instruments. The PGx enables direct surface testing of almost any 3D object without having to cut the sample to fit. Simply place the PGx Portable Contact Angle Meter on your sample or part and press a single button. The PGx automatically delivers a precisely calibrated drop onto the surface and the built-in camera captures a video sequence of the surface wetting at a rate of 80 frames per second. The results are displayed as a static contact angle or dynamic wetting as a function of time, providing detailed information about the liquid/substrate interaction in a truly portable instrument.

Proof of concept trials
We understand that plasma technology may not be familiar to you, that’s ok, it’s what we’re here to help with.
We will be happy to discuss your expectations, both technical and commercial, and then undertake some initial proof of concept plasma treatment trials, totally free of charge, to help you determine if one of our range of plasma treatments could be useful.
We have the extensive technical knowledge, applications knowledge and of course a wide range of plasma treatment and surface test facilities at our disposal.
If plasma treatment isn’t suitable (and sometimes it isn’t!), we can help you to determine that as well, and often, we can suggest alternatives or point you in the right direction.
We carry a wide range of rental plasma treatment systems in stock at any one time, both standard and customised, and available at great rates for immediate dispatch.
If an immediate purchase of a system is not the most efficient method for you and should you decide, after trying the equipment and processes, that plasma treatment is right for your product, we even offset part of the rental payment against the eventual outright purchase.
You can play it safe with us, rent a plasma treatment unit first, then decide. We firmly believe that there isn’t a process or problem that can’t be solved by working together.
Plasma process development
During plasma processes development, we work hand in hand with our clients to customise a plasma treatment solution that best meets their needs. We undertake in-house or on-site process development for a wide range of new applications, drawing on extensive real-world experience.
In the first instance, we are happy to receive your samples after initial discussion and in order to determine an optimum treatment. These preliminary tests are always free of charge. After the initial process development, a treatment plan can be detailed. At this stage, we are generally ready to move forward to quote a specific system/treatment(s) exactly matched to your product, a service which ultimately reduces your risk.
- Access to our extensive process library
- Comprehensive surface testing methods
- Adhesion and coatings processes
Contract plasma treatment
We offer a fast and cost-effective contract plasma treatment service for both small one-off requests and ongoing production.
Contract treatment is a cost-effective way of tapping into the unique benefits of plasma treatment where the cost of capital equipment isn’t justifiable, for example where one-off or short-term contracts have been awarded.
Our plasma treatment and testing facility is equipped with a comprehensive range of plasma treatment equipment for both cleaning, surface activation, coating and etching.
Both vacuum and in-line atmospheric plasma treatments can be utilised for contract treatment with fast turnaround times to suit.
