Universal Closures are specially designed with wider, gentler sealing ridges to ensure a leak-proof seal for thick walled dialysis tubing without damaging the membrane. 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 to ensure a proper seal.

Made from nylon material, the compatibility Universal Closures with specific solvents should be confirmed on the Repligen Chemical Compatibility table.
