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.
