The SpectraPor® Float-A-Lyzer® Dialysis Device is a unique and leak-proof, ready-to-use device designed for easy and convenient dialysis of small sample volumes from 1 – 10 ml. The device is made with high purity Biotech Grade Cellulose Ester (CE) membrane in 9 MWCOs from 0.1-1,000 kD. Screw cap lid and included pipette allow for easy loading, in-process testing and sample retrieval without the risk of needle punctures.
Biotech CE membrane exhibits a fair chemical compatibility and tolerates pH 2-9 and temp 4-37 °C. Exposure to most organic solvents is not recommended and should be confirmed on the Repligen Chemical Compatibility table.
FEATURES
Tubular membrane allows for maximum surface area and minimum volume uptake & dilution. Float ring ensures buoyancy and vertical orientation
Screw-on cap and pipette provides easy and safe sample loading and in-process testing with no dangerous needles
Cylindrical shape provides open access for 95-98% sample volume recovery
9 MWCOs from 0.1 - 1,000 kD for all dialysis applications from small peptides to large nanoparticles
Achieve 98% sample purity with Biotech CE membrane, no heavy metal and sulfides.
Drug Dissolution: Controlled release for dose determination
USP Apparatus 2 and 4 compatible
