Autoclavable, Spectra/Por®Weighted Dialysis Tubing Closures contain an acid-washed, fluorocarbon coated, stainless steel bar. When applied to the bottom of the dialysis tubing, the closure maintains a vertical orientation of the sample.
Autoclavable Spectra/Por®Magnetic-weighted Dialysis Tubing 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 complete submersion and gentle rotation of the sample on a stir plate.
The ultimate sample buoyancy and vertical orientation can be achieved by applying both a standard and a weighted Spectra/Por® Dialysis Closure to opposite ends of the same dialysis tubing. The Paired Closures are autoclavable.
