Tubing Closures are the preferred method for sealing dialysis tubing to minimize the risk of sample leakage. While tied knots often leak, damage the membrane and are difficult to open, Tubing Closures are easy to apply, ensure a leak-proof seal and are re-usable.
Universal Tubing Closures
While Universal Closures provide a gentle seal for all types of dialysis tubing, it is required for use with Cellulose Ester dialysis tubing.
