Bettsep® ion exchange media designed for the purification of biological acromolecules. The substrate of Bettsep® is monodisperse polymer microspheres. Compared with dextran, agarose and cellulose, polymer microspheres have advantages of high mechanical strength and excellent pressure resistance. 1000 Å pore diameter ensures the free entry and exit of biomacromolecules. With GLK® unique surface coating technologies, the hydrophilic surface of microsphere substrates ensures high biological compatibility. And the monodisperse particle size effectively reduced the barrier of column pressure and mass transfer.  

Advantages: 
1. For the capture of biological macromolecules, and the purification of middle process. 
2. High production efficiency 
3. High flow rate, high loading capacity, high purification efficiency. 
4. Excellent chemical stability, alkali cleaning conditions, long lifetime.
