GeBAflex Dialysis Tubes – Efficient Sample Dialysis for Small Volumes
GeBAflex dialysis tubes are specifically designed for fast and reliable dialysis of small sample volumes. They offer a simple and effective solution for sample purification in molecular biology and biochemistry laboratories. The tubes are used with the included float in a beaker filled with dialysis buffer.
Available in Mini (10–250 µl), Midi (100–800 µl), Maxi (0.1–3 ml), and Mega (3–20 ml) sizes, they cover a wide range of applications.
With molecular weight cut-offs (MWCO) ranging from 1 kDa to 50 kDa, GeBAflex tubes are suitable for a broad spectrum of applications, tailored to the specific size of the target molecule.
The membranes are made from high-purity regenerated cellulose, free from heavy metals and sulfides. This ensures the integrity, purity, and compatibility of samples, even in sensitive applications.
