Dialysis Tubing Closures

Using resealable closures is the preferred method for sealing dialysis tubing without the risk of leaking. Tied knots are nearly impossible to open & re-seal and often result in damaged, leaking membranes. Spectrum offers two classes of Dialysis Tubing Closures, Universal Closures for use with all membrane types and specialized Spectra/Por® Closures with additional functional benefits for use only with Standard Grade tubing.


Universal Closures for All Membrane Types


Features & Benefits
Specially designed with gentle sealing ridges, Universal Closures are the ideal all-purpose closure that creates a reliable seal with all membrane grades, types and thicknesses. Available in a variety of colors for easy sample identification.

For best results, select a pair of closures that has a sealing width 4 to 10 mm longer than the flat width of the dialysis tubing. This assures a proper seal without membrane tearing.
