Dialysis Tubing Closures

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.

SpectraPor® Tubing Closures

SpectraPor® Closures are available in 3 functional times (Standard, Weighted and Magnetic) intended for use with only Regenerated Cellulose dialysis tubing.

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.
