Perfluoroalkoxy (PFA) resin bottles in which the elution amount of metal impurities is extremely small are used as containers.

In addition, as part of our efforts to assist environmental conservation we have implemented a "container link system" for the use of our customers.

This is a system for customers who continuously use our analytical reagents.

When used containers are returned in advance of the next order, an amount corresponding to the cost of the containers is discounted from the invoice amount of the next order.
