Smaller pack sizes are also worth considering for those products which may deteriorate on atmospheric exposure.

Certified reference solutions and volumetric reagents should be gently shaken before use to maintain homogeneity which can be degraded due to water condensation on the inner surface of the container.

Do not return unused material and always replace the original closure immediately after use.

Partially-used bottles of solvents should be purged with dry nitrogen or other inert gas before replacing the cap in order to maintain the optimum UV transparency.

In general, a comfortable ambient room temperature (15-25°C) for laboratory personnel is fine for most products but where special storage conditions are required, such as refrigeration, this is stated on the label.

Information regarding stability and storage of reagents is an integral requirement of modern Good Laboratory Practice (GLP) and ISO 17025 management.

So to obtain the best performance from ROMIL products they should be used within the defined period of time and stored in such a way that minimises impurity build-up.

To prevent contamination it is good practice to dispense from the container rather than withdraw product with pipettes or other glassware.
