Spectra/Por^® Biotech Grade Membranes: CE & RC

Product Searches:

Only Spectrum offers Biotech grade dialysis membrane for those critical applications requiring stringent MWCO's and membrane purity. Since these synthetic membranes are made using a process free of heavy metal contaminants and sulfides, they are ultra-pure and require no cleaning or pre-treatment. Simply rinse with DI water, apply Universal Closures and load sample! Spectrum offers 2 different Biotech grade membrane types to meet the different demands of laboratory dialysis applications: Cellulose Ester (CE) & Regenerated Cellulose (RC).

ADVANTAGES OF BIOTECH MEMBRANES

• No impurities for critical separations and unaffected molecular activity
• Rigidly controlled porosity for better separation (retention and passage)
• 2 tubing types available for different applications (CE & RC)
• Large selection of MWCO's & tubing sizes
• Only Ready-to-Use dialysis devices with biotech grade membrane.

Biotech Grade CE Tubing & Trial Kits Learn More >	Biotech Cellulose Ester (CE) Membrane Biologically inert, ultra-pure, largest selection of concise MWCO's (0.1 - 1000 kD) and sizes for desalting, isolating ionic species and macromolecular purifications. More sensitive to harsh conditions and solvents. Generally tolerates weak or dilute acids & bases and mild alcohols with only a slight change to the MWCO. Exposure to most organic solvents may damage CE membranes. Use with pH 2-9 & temp 4-37 °C. Available in 10m/roll tubing, trial size dialysis kits (1m) and Ready-to-Use Dialysis Devices.
Biotech Grade RC Tubing & Trial Kits Learn More >	Biotech Regenerated Cellulose (RC) Membranee Crafted from a regeneration process to yield superior physical tolerances and chemical compatibilities with the same high purity. Tolerate concentrated-weak acids & bases, dilute-strong acids & bases, most alcohols and some mild or dilute organic solvents. Exposure to strong polar or organic solvents may damage RC membranes. Use with pH 2-12 & temp 4-60 °C. Available in dialysis tubing in 5m/roll tubing and trial size dialysis kits (0.5m).
Biotech Ready-to-Use Dialysis Devices Learn More >	Biotech Ready-to-Use Dialysis Devices Pre-assembled and Ready-to-Use dialysis devices with ultrapure Biotech Grade CE tubular membrane for ultimate convenience, easy handling & total sample recovery. No accessories required. 3 types of dialysis devices available: Float-A-Lyzer® G2 for small volume dialysis (1 - 10 ml) Micro Float-A-Lyzer for microdialysis (100 - 500 µl) Tube-A-Lyzer® for rapid dynamic dialysis (8 - 30 ml)
