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.

FEATURES

  • 2 ready-to-use volume sizes (100-200 µl and 400-500 µl)
  • 7 concise MWCO’s for better separations & selectivity
  • High purity Biotech Cellulose Ester (CE) membrane
  • Included syringe and Luer sample port for easy access (no needles)
  • Self-standing, self-floating and interlocking
