Spectra/Por® tubing trial kits are available in 1 and 5 m lengths. They are an excellent choice for applications that require only a small amount of dialysis tubing.

• Hydrophilic, symmetric porosity

Spectra/Por® 1, 2, 3, 4 and 5 come in two different tubing diameters and 1 or 5 m lengths for trial kits with a Biotech regenerated cellulose (RC) membrane. This covers all cut offs in the Spectra/Por® RC dialysis tubing range: 3,5 kDa, 6 - 8 kDa and 12 - 14 kDa. They contain one standard (for buoyance) and one weighted closure (for orientation).

In addition, there are trial kits with 1 m Biotech cellulose ester (CE) tubing membrane, representing all 9 different MW cut offs: from 100 to 1 million Da. The standard tubing diameter for all CE trial kits is 10 mm and two universal closures are included.
