What is the max temp and time your SC490 tubes can handle with a strong to medium acid?

Polypropylene is safe to use up to 130°C. Our digestion cups are not recommended for long term storage of concentrated acids, but they are safe to use with acidic solutions. They are designed to be used with mixtures of hydrochloric and nitric acids at temperatures near 100°C. They are safe to use under these conditions almost indefinitely.
