"Contact angle measurement" is a commonly used inspection method to assess the strength of atmospheric pressure plasma effects. A droplet of water is placed on the surface of the target material, and the angle at the point of contact with the material is measured. The smaller the value, the more hydrophilic (the better the affinity for water) the material is. Our company uses the Ellipse (Tangent-1) method, which analyzes the contour of the water droplet by tracing it as separate parts of two ellipses, as the standard analysis method. 【Other Analysis Methods】 ■ 1/2θ Method ■ Tangent Method ■ Young Laplace Method ■ Circle Method *For more details, please download the PDF or feel free to contact us.

We examined the sterilization effect of atmospheric pressure plasma on microorganisms attached to the glass surface of smartphones and will introduce the details of the microorganisms involved and the results. Microorganisms were collected from the "untreated area" and the "area irradiated with atmospheric pressure plasma" on the glass surfaces of two staff members' smartphones using cotton swabs, and cultured. We then evaluated the sterilization effect by comparing the colonies of microorganisms formed on the Petri dishes from both areas. As a result, mainly "bacteria from hands" and "bacteria from the environment" were identified, with at least three types of microorganisms observed. On the plates after plasma irradiation, the number of bacterial or yeast colonies decreased compared to the "untreated" ones. Fungi and actinobacteria were still observed after plasma irradiation. [Observed Microorganisms] ■ Bacteria or Yeast ■ Filamentous Fungi (Mold) ■ Actinobacteria *For more details, please refer to the related links or feel free to contact us.

At Aqua, we perform various resin processing. We handle a wide variety of resin processing, including polyvinyl chloride, polyethylene, polyacetal, PTFE, PEEK, ABS, polycarbonate, and Bakelite. Additionally, we also deal with other special gear processing and brush manufacturing. Please feel free to contact us when you need assistance. 【We can solve the following problems】 ■ The dimensions of off-the-shelf products are insufficient, and I want something made from special resin for chemical use. ■ I need something that is not available as a ready-made product for research equipment. ■ I want to fix sensors, nozzles, units, etc. ■ I want to remake a broken part. ■ The cover of the device is broken, and I want to add a cover here as well. ■ I am looking for a company that can manufacture device enclosures. *For more details, please refer to the related links or feel free to contact us.
