Biotech Membrane

Spectra/Por® Biotech Membranes are the newest generation of Spectra/Por® dialysis membranes. The principle benefit of Spectrum’s Biotech membranes over traditional membranes is the manufacturing process which eliminates the use of metal salts. This process provides high purity membranes and eliminates the need for special cleaning treatments. Spectra/Por® Biotech membranes require only minimal rinsing to remove the preservative if present. Biotech Regenerated Cellulose (RC) membranes are used when resistance to various organic solvents is required. Biotech Cellulose Ester (CE) membranes provide a wide selection of rigidly controlled MWCO’s ranging from 100 to 1,000,000 Daltons.

Applications
Spectra/Por Biotech membranes are ideal for many applications such as:
→ Removal of salts, surfactants and solvents
→ Buffer and pH adjustment of sample solutions
→ Concentration of protein, peptides or antibodies
→ DNA electroelution
→ Preparation of diluted proteins prior to electrophoresis
→ Removal of contamination micromolecules
→ Binding studies
→ Tissue culture extract purification
