Description

Aplicación

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

Precaución

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