SpectraPor® Micro Float-A-Lyzer®
Micro Float-A-Lyzer® ready-to-use dialysis devices are all made with proprietary Biotech Grade CE dialysis tubing, preassembled with volume specific lengths of membrane tubing and designed to maximize convenience, ease-of-use and sample recovery.
Unique design
Tubular membrane for max surface area with incorporated air bladder, stand and interlocking pegs
Easy to use
Screw-on cap and pipette provides easy and safe sample loading and in-process testing with no dangerous needles
Total sample recovery
Syringe aspiration of clamp sealed membrane for 90-98% sample recovery
Broad MWCO range
7 MWCO’s from 0.1 - 100 kD for molecular selectivity from small peptides to large nanoparticles
High purity
Achieve 98% sample purity with Biotech CE membrane, no heavy metals and sulfides
Featured application
Drug Dissolution: Controlled release for dose determination
USP Apparatus 2 and 4 compatible
Designed for ultimate convenience, the Micro Float-A-Lyzer® significantly improves handling and dialysis of microliter volume samples. This ready-to-use dialysis device is constructed with high purity Biotech Grade Cellulose Ester (CE) membrane in 7 concise MWCOs from 0.1-100 kD for better molecular selectivity. The Luer® port and included syringe allow for easy loading, in-process testing and sample retrieval without risking needle punctures.
Biotech CE 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.
