설명

애플리케이션

ZerO₂ products are rigorously degassed with highly pure inert gas providing solvents and solutions (anhydrous if specified) with very low residual oxygen content.

주의사항

Supercools easily and remelts slowly at room temperature. Solidified product can be re-liquified by warming to room temperature without detriment to the product.
