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
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.
