Always make an immersion test before choosing a tube material for critical applications. Immerse a short length of the tubing (always available from Watson-Marlow Pumps or its distributors) in a closed container of the fluid for 48 hours, and then examine it for signs of attack, swelling, embrittlement or other deterioration.
*Important note - The ReNu pumphead contains lubricant. The lubricant components are Glycerol (C3H8O3) 50-100% w/w, Glycol (C2H6O2) 2.5-10% w/w, Water (H2O). It is the users responsibility to ensure chemical compatibility with the lubricant in the ReNu pumphead. Local health and safety regulations must be complied with. Contact your local Watson-Marlow representative for guidance.
