This is a device that allows SPG emulsification with a small amount (a few ml). It enables adjustable particle size and easily achieves monodisperse emulsions.
This is a disposable type SPG device that allows for monodisperse and adjustable particle size emulsions with just a few milliliters and a small amount of sample. SPG emulsification is characterized by its ability to adjust the particle size of monodisperse emulsions, and it is also very static compared to other high-speed stirring or high-pressure emulsifications, making it suitable for emulsifying sensitive polymer materials and pharmaceuticals. Additionally, it can emulsify with a very small amount, so it is ideal for emulsifying expensive drugs or reagents. The "pumping connector" allows for manual emulsification in a short time using the SPG permeation emulsification method. We also offer a lineup of "direct connectors" and "filter kits" that utilize the SPG direct emulsification method to prepare highly precise monodisperse emulsions.

Company information
SPG stands for S "Shirasu," P "Porous (Pore)," and G "Glass," and it is a type of porous glass that can be designed arbitrarily within a wide range of pore diameters from 0.1 to 50 μm. It is a unique inorganic porous material with a narrow pore distribution and a high porosity rate. Initially, research and development focused on the application of SPG technology in the medical field. However, various research institutions have published their findings, and it is now applied in a variety of fields including medicine, pharmaceuticals, chemistry, electronics, cosmetics, and food. The representative method of using SPG, known as the "membrane emulsification method," allows for precise control over the size of the desired emulsion by using it as a dispersion membrane, enabling the preparation of uniform monodisperse emulsions. Currently, SPG application technology contributes to the creation of new product values, ranging from disposable devices that prepare several milliliters of pharmaceuticals on-site in medical settings to the manufacturing processes for monodisperse emulsions in factory scales of several tens to hundreds of liters, as well as its use in semiconductor processes.
