Plastic containers for balling dosing

[chema]

I'm redesigning my dosing station for alkalinity, calcium and magnesium and I'm trying to find containers that fit in the available space. What is the best type of plastic for the containers? Are SAN or polypropylene plastics OK for this purpose?

Polypropylene is suitable for almost any reef application, as long as you are not heating it.

Randy, thank you very much. That was also my guess. SAN is transparent, but I'm afraid not as chemically resistant as polypropylene.
