PureCube Activated MagBeads XL

Agarose magnetic beads typically have particle sizes of 10-40 µm. However, for special applications, MagBeads with exceptionally large bead sizes can be useful.


Agarose MagBeads with 90 µm diameter are available as PureCube MagBeads XL, with a large variety of chemical activation modifications. Biomolecules can be coupled to the MagBeads using easy to follow protocols.


For even larger bead sizes of several hundred microns in diameter, please contact us for a customized solution.

Activated MagBeads XL are available on request. Please contact us to learn more.
