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) for better MW selectivity & Regenerated Cellulose (RC) for better chemical tolerance.
ADVANTAGES OF BIOTECH MEMBRANES
Ultrapure for critical separations
Does not interfere with macromolecular activity & function
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.
Biologically inert and ultra-pure, Biotech CE is available in the largest selection of concise MWCO's (0.1 - 1000 kD)
and sizes to provide better molecular separation 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 and trial size dialysis kits (1m).
Spectrum's premium dialysis membrane is crafted from a regeneration process to yield superior physical tolerances and chemical compatibilities
while maintaining the same high purity. Tolerates 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).
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:
