Magnetic Macroporous Bead Cellulose MG
Pure or its derivatives for magnetic separations | General informations
Macroporous Bead Cellulose MG and its derivatives can be used for izolation or magnetic modification of biologically active matters, cells, sub-cellular components, contaminants of environment or other matters of studied systems. Especially advantageous is their use in microbiology, cell biology, medicine, biochemistry, biotechnology and ecology.
All types of non-magnetic sorbents can be delivered also as magnetic sorbents used for magnetic separations. Magnetic sorbents can be delivered in the same assortment as non-magnetic sorbents. For example: Are you interested in → IONTOSORB SHP? We can produce you MAGNETIC SORBENT IONTOSORB SHP. But SHP 100 or SHP 200, because Magnetic Macroporous Bead Cellulose and its derivatives are made in these porozities only:
|Porozity||Particle size [microns]|
(50), 100, 200
|30 - 50|
|50 - 80|
|80 - 100|
Basic properties of derivatives IONTOSORB are the same both for magnetic or non-magnetic beads.
Magnetic macroporous bead celulose (types MG) is produced by the same technology as a classic macroporous bead cellulose (types MT) with the only difference that MG has in its matrix built in Fe3O4 in amount min. 30 % related to dry matter.
These Fe3O4 particles are present in the cellulose matrix and therefore macroporosity is not influenced by the Fe3O4 particles. This fact corresponds also with a B.V. for Iontosorb MG re-calculated to MT.
If an average experimental B.V.value for MG = 7.4 mlg-1 of dry matter MG and a determined ash content 29.7 %, then the bellow given equation can be used for the re-calculation of the found B.V. of MG to a calculated B.V., which would correspond to the MT without Fe3O4.
Calculation of B.V. value from MG to MT:
Ash Content [%] for MG,
B.V. found for MG [ml-1 grame dry per MG]
|Porosity of MG||B.V. for Iontosorb MG [ml g-1 dry]|
Macroporous Bead Cellulose MG types are highly porous gels well accessible for large macromolecules, as it is shown in this Figures.
