Spectra/Por* Weighted and Magnetic Closures

Made of polypropylene and contain an acid-washed, fluorocarbon-coated, stainless steel bar imbedded on the reverse side. When used with a regular closure, the tubing will remain in a vertical position and increase the rate of dialysis. Not for use with CE tubing.
Magnetic weighted closures allow for the complete submersion of the dialysis tubing and when used with a magnetic stir plate a slow spin motion of the dialysis tubing takes place without the use of a stir bar. Teflon* coated. Not for use with CE tubing.
