Spectra/Por® 6 Standard RC tubing is conveniently pre-equilibrated in water, eliminating the need to soak the membrane to remove glycerin and hydrate the membrane. This ready-to-use membrane is packaged wet in a preservative solution of 0.05% sodium azide. Simply rinse away the preservative solution with DI water, load the sample and dialyze. The tubing is available in 10 m/roll to provide better economy for applications requiring larger amounts of tubing.
