SEKISUI Clean bottle solution.
Particle control and carefully selected low-elution-grade raw materials are used in many high-purity chemicals, as well as in medicine, cosmetics, and fragrances. 100cc-1L bottles, 10L-20L tanks, and 200L drums are available in clean containers.
Integrated response from R&D to mass production
It is easy to scale up from laboratories to mass production.
Since the same clean raw material is used in all the capacity, it is not necessary to evaluate the performance of the container at the time of scale-up.
Superior Clean Performance to Maintain Content Fluid Quality
To limit the elution of impurities into the contents
Complies with UN standards required for transporting hazardous materials
All volumes comply with UN standards (UN Recommendations on the Transport of Dangerous Goods)
Light-resistant clean containers
Light-shielding clean containers with multilayer structure are most suitable for photosensitive materials.
- Low-elution material is used for the inner layer (wetted layer) to suppress elution of metal impurities.
- Use a gray pigment for the outer layer to ensure light-shielding properties.
Quality control
Pursuing the highest quality through thorough management of each process
Thorough traceability
Production in a clean environment
