Spectra/Por® Universal Closures, Spectrum® Laboratories

Nylon closures lock gently over rigid membranes such as cellulose ester (CE) and polyvinylidene fluoride (type F) tubing, providing a strong, leakproof seal

Closures can also be used with traditional regenerated cellulose (RC) tubing. Sink in water. Can be sterilized with gamma radiation, ethylene oxide, ethanol, or formaldehyde. Not autoclavable. For best results, select a closure 4 to 10mm wider than the flat width of the membrane or tubing.
