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.

SpectraPor^® Micro Float-A-Lyzer Dialysis Device

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.
