  • Q:

    Is there an exact wall size for this product? It appears to be about 6mm???

      This tubing is designed to extremely tight tolerances for use specifically in the MasterFlex peristaltic pump heads. Because of this, only the internal diameter is published, to allow for barbed fitting selection. The wall thickness and the outer diameter is considered proprietary and is not published.

  • Q:

    I am working with continuous crystallizers, so I need the best tubing for solid/liquid flows. Right now I am using PVC tubes but crystals attach to the surface of the tubes. Which tubes do you recommend for my application.

      If the fluid is water (or another liquid compatible with silicone), I would suggest BioPharm Plus. It has an ultra-smooth inner bore to reduce particle entrapment. It has longer life and lower spallation compared to other silicones, and it comes in the size I/P 89. The part number is 96441-89.

      Another option would be Tygon E-Food. It has an extremely smooth bore as well. The part number would be 06418-89.
