• Radiation sterilization/sterilizer
• UV/visible spectrophotometer

When radiation is irradiated onto polymer materials such as plastics, excitation or ionization occurs in the nearby molecules that the radiation passes through, resulting in the generation of highly reactive active species. Through the reactions of these active species, the cleavage of polymer chains (radiation decomposition) occurs, or reactions that bond polymer chains together in a bridge-like manner (radiation crosslinking) take place. Additionally, if a highly reactive compound is mixed with the polymer along with the active species, it is possible to add new branches to the original polymer chains (radiation graft polymerization). 【Radiation Modification】 ■ Radiation Decomposition: Cleavage of polymer chains ■ Radiation Crosslinking: Reaction that bonds polymer chains together in a bridge-like manner ■ Radiation Graft Polymerization: Adding new branches to the original polymer chains *For more details, please refer to the PDF document or feel free to contact us.

• Radiation sterilization/sterilizer

Sterilization refers to the process of reducing the number of microorganisms or removing specific microorganisms, while sterilization means bringing the possibility of microbial growth as close to zero as possible. There are various sterilization methods, including general flame sterilization and dry heat sterilization, but the methods widely used in industry are high-pressure steam sterilization, gas sterilization, and radiation sterilization. Ultraviolet light is convenient for disinfection but is not suitable for sterilization. Additionally, filtration sterilization methods using special filters may be employed for sterilizing liquids and gases. 【Features】 - Minimal temperature rise during processing - No residual substances - Processing possible in the final packaging state - Continuous processing possible - Easy process management *For more details, please refer to the PDF document or feel free to contact us.

• Radiation sterilization/sterilizer

Our company provides one of the largest comprehensive radiation irradiation services in the country.
