Description
Spectra/Por® Float-A-Lyzer® G2, amber, is a ready-to-use dialysis device for laboratory separation, desalting, and buffer exchange of macromolecular samples. This CE-marked unit provides a molecular weight cut-off (MWCO) of 300000 and a sample capacity of 10 ml, addressing workflows that retain large proteins, complexes, or polymers while allowing smaller solutes to diffuse away. The floating G2 design simplifies placement in dialysis reservoirs and supports gentle equilibration with minimal handling. Amber colour coding enables rapid visual identification of the high-MWCO variant among other Spectra/Por® devices. Supplied in packs of 12 pieces from manufacturer REPLIGEN, the product fits protein chemistry, biopharmaceutical process development, and analytical sample preparation. Consistent membrane performance and a self-contained format reduce setup time compared with traditional tubing. The 10 ml working volume is practical for pilot and analytical scales commonly used in research and quality-control laboratories focused on high-molecular-weight targets.
This article belongs on Dialysis tubing & devices, in Filtration.

Questions about Spectra/Por® Float-A-Lyzer® G2, amber, CE, MWCO 300000, capacity 10 ml
What is this article?
Spectra/Por® Float-A-Lyzer® G2, amber, CE, MWCO 300000, capacity 10 ml is the article on this page. Luminix Health distributes REPLIGEN for laboratory use. It sits in Dialysis tubing & devices, inside Filtration, in Consommables.
Dialysis tubing is a membrane tube that lets small molecules leave a sample and keeps macromolecules inside, until both sides approach equilibrium. The molecular-weight cutoff and the flat width are the specification. It is a slow method. The tubing has to be wetted and rinsed as the pack says.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
