04 · Handling and storage
Storing and handling Glutaraldehyde
Storage conditions
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature: -20 °C. Store under inert gas. Air sensitive.
