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

Available in three functional types, SpectraPor® Tubing Closures are intended for use with Regenerated Cellulose (RC) dialysis tubing to ensure a leak-proof seal. These closures are not recommended for use with Cellulose Ester (CE).

Universal Tubing Closures

Universal Tubing Closures can be used with all types of dialysis tubing to provide a leak-proof seal. These closures are required for use with Cellulose Ester (CE).
