How to Deal With Solvents

Use clean bottles only.

Exchange water-based solvents daily.

Select solvent volume to be used up within 1 – 2  days.

Use only HPLC-grade solvents and water filtered through 0.2 µm filters.

Label bottles correctly with bottle content, and filling date / expiry date.

Use solvent inlet filters.

Reduce risk of algae growth: use brown bottles for aqueous solvents, avoid direct sunlight.
