Best Practices
Seal Wash
Seal Wash guarantees a maximum seal life time. Use Seal Wash:
• When using buffers with elevated salt concentrations
• When using volatile solvents with non-volatile additives
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.
