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. Repligen 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.
