Elution of metal ions and TOC is infinitesimal

Clean materials that elute extremely few heavy metals are employed for making these valves and fittings.

Elution of TOC is especially few.

The smoothness of the inner surface of these pipes is so high that almost no irregularities and voids, which cause the propagation of bacteria, are on the inner surface of these pipes.

They are made of heat resistance, rigid polyvinyl chloride, so they can be employed as piping materials for hydrothermal sterilization.

As the coefficient of linear expansion of these pipes is smaller as compared with other synthetic resin pipes, pipeline's expansion treatment can be easily done.

Inexpensive and economical in comparison with piping materials for ultra-pure water, such as PVDF and SUS piping materials. Also, a large assortment of types is available.

Pipes are fitted with end caps, and valves and fittings are degreased. They are consistently cleansed as clean pipelines.
