"Ultrasonic Powder Sifter" Ultrasonic Oscillator Series *Test and rental units available

From round and square frames to metal plates, measures against powder adhesion and clogging are possible! Achieve stable sieving even in explosion-proof and temperature-changing environments!

It is possible to apply ultrasonic vibrations to any metal shape. From round and square frames to metal plates (such as hoppers), it helps prevent powder adhesion and clogging, thereby improving classification efficiency. Since the converter and cables can be placed outside the powder supply area, stable ultrasonic sieving can be achieved even for powder characteristics that are sensitive to explosion, temperature changes, and cleaning. It is also compatible with applications such as ultrasonic mesh cleaning and powder transportation. *Please consult us for test and rental machines. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to inform you that we will be exhibiting our products at the 63rd Annual Meeting of the Biophysical Society of Japan. If you are planning to attend, please be sure to stop by. ❚ Products to be Exhibited - Auto Patch Clamp System | Port-a-Patch mini This compact system eliminates the need for a microscope, vibration isolation table, manipulator, and Faraday cage, which are typically required for conventional patch clamp experiments. It does not require specialized skills or experience, allowing for easy data acquisition and verification. - Artificial Lipid Bilayer Experiment Device | Orbit mini This device allows for easy measurement of channel activity at the single-molecule level. It enables the formation of lipid membranes, reconstitution of membrane proteins, and single-channel measurements using only a micropipette in experiments utilizing artificial lipid bilayers, facilitating functional and structural analysis of target membrane proteins and evaluation of drug effects. - Liposome Preparation Device | Vesicle Prep Pro This is the world's first device capable of producing giant unilamellar vesicles (GUVs) with diameters ranging from 1 to 30 μm without the use of organic solvents, utilizing the electroporation method (vibrating hydrated lipid films in an alternating electric field).
