Description
Ion exchange resin ROTI®Change 50 W x 4 is an analytical-grade cation exchange resin in the H+-form for laboratory separation and purification tasks. The mesh range is 50–100, offering coarser beads that favour higher flow and easier column packing compared with finer cuts. Density lies between 1,15 and 1,3 g/cm³, which supports calculation of bed volumes and slurry ratios. Manufacturer Carl ROTH positions this ROTI®Change type for environmental analysis, chromatography and ion chromatography workflows. Analytical grade and defined H+-form help maintain consistent exchange performance when protocols specify strong-acid cation resin. The 50–100 mesh fraction suits applications that prioritise throughput and lower back-pressure over ultra-fine resolution. Typical uses include sample pre-treatment, deionisation steps and preparatory exchange ahead of further analysis. Documented mesh size, ionic form and density allow straightforward comparison with existing resins in validated methods. Follow standard laboratory handling for ion-exchange media and review the safety data sheet prior to use.

Questions about Ion exchange resin ROTI®Change 50 W x 4, 25 g, 50-100 mesh, analytical grade
What is this article?
Ion exchange resin ROTI®Change 50 W x 4, 25 g, 50-100 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.
