Dialysis Tubing Closures

…entirely of Nylon 66, closures have an operating temperature range of 0-90C, and can be sterilized with ethylene oxide, gamma-irradiation, ethanol, or formalin.Different colors can be used to code samples. For best results, select a closure 4-10 mm wider than the flat width of the dialysis tubing.

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.

…the same dialysis tubing. The Paired Closures are autoclavable. Autoclavable Spectra/Por Magnetic-Weighted Closures contain a magnetic fluorocarbon coated stainless steel bar, eliminating the need for conventional stir bars. Applied to the bottom end of the dialysis tubing, this closure provides…

…require no cleaning or pre-treatment. Simply rinse with DI water, apply Universal Closures and load sample! Spectrum offers 2 different Biotech grade membrane types to meet the different demands of laboratory dialysis membrane applications: Cellulose Ester (CE) & Regenerated Cellulose (RC). …

Designed for the general dialysis of larger sample volumes, the Ready-to-Use Sack consists of a 60 cm length of Spectra/Por 1, 2, 3 or 4 tubing, sealed at one end with a Spectra/Por Closure and a funnel attached to the other for easy filling. Simply fill, apply closure & cut.

Since Spectra/Por Standard Closures float, they aid in buoyancy and vertical orientation when applied to the tubing top end. Autoclavable and available in a variety of colors for easy sample identification. For use with Spectra/Por Standard Regenerated Cellulose membranes only.

Ideal for small volume dialysis or evaluation of membrane for an application, multi-purpose standard Regenerated Cellulose (RC) tubing is now available in 5 m length trial kits with a pair of tubing closures.

Ideal for small volume dialysis or evaluation of membrane for an application, biotech grade Cellulose Ester (CE) & Regenerated Cellulose (RC) tubing is now available in 1 m & 0.5m length trial kits respectively with a pair of tubing closures.

…closure, 1 top closure and 2 bottom weighted closures. Closure kit includes 5 sets designed for sealing dialysis tubing ≤ 31mm flat width for Process Scale System. Each set includes 2 hanging closures and 2 standard closures. Closure kit includes 5 sets designed for sealing diaysis tubing…

Autoclavable, Spectra/Por Weighted Closures encase an acid- washed, fluorocarbon coated, stainless steel bar. When applied to bottom end of the dialysis tubing, the Weighted Closure acts like an anchor to maintain a vertical orientation of the sample.

…the closure, fold tubing in half before closing Closures are lighter than water         Normally used in tandem with a weighted closure or a magnetic closure. Attach a regular closure on the top of a dialysis sack and a weighted closure or…
