Innovalene® 4500 series are formulated to resist ethanol as well as strong acid and base. As a peristaltic pump tubing, its pump life is as long as 500 hours under 600 rpm as measured by MasterFlex standard pump. Unlike traditional pump tubing, one great benefit of Innovalene® 4500 series is its flow rate stability. It is observed that flow rate of Innovalene® 4500 series stays within 3% over its pump life span and customers benefit from stable flow rate as welll as superior chemical resistance.
