Description
Ion exchange resin Roti®change 50 W x 4 is an analytical-grade ion exchange resin in the H+-form with a particle size of 100-200 mesh. Density is stated as 1,15 to 1,3 g/cm³, supporting practical handling during column packing and bed preparation. The product is The 100-200 mesh fraction suits separation methods that specify this particle range for flow and packing behaviour. Analytical-grade resin from manufacturer Carl ROTH provides a defined option for laboratories that standardise on Roti®change 50 W x 4. The H+-form describes the ionic state as delivered, ready for conditioning or use according to the chosen protocol. Density values assist volume estimates when preparing resin beds. Mesh, grade and form data help match internal methods and published separation procedures.

Questions about Ion exchange resin ROTI®Change 50 W x 4, 100 g, 100-200 mesh, analytical grade
What is this article?
Ion exchange resin ROTI®Change 50 W x 4, 100 g, 100-200 mesh, analytical grade is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Sorbents, silica gel & ion exchangers, inside SPE & sample preparation, in Chromatography equipment.
Loose sorbent, silica gel and ion-exchange resin are the phases bought in bulk to pack a column or to stir into a solution. Particle size and activity, or the ion-exchange capacity, are the specification. A TLC silica and a flash silica of different particle sizes are not the same separation.
Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
Which category should I open next?
The category is SPE & sample preparation. The sub-category is Sorbents, silica gel & ion exchangers. The catalogue is Chromatography equipment.
Shelves beside this one are SPE cartridges & columns and Flash, empty & glass chromatography columns.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
