Solvent Information

Observe the following recommendations on the use of solvents.
• Follow recommendations for avoiding the growth of algae, see
• Small particles can permanently block capillaries and valves. Therefore,
• Avoid or minimize the use of solvents that may corrode parts in the flow path.
