Description
Dowex® 1 X 2 is a strongly basic anion-exchange resin in the chloride form, offered here as the finer 200–400 mesh grade with CAS number 9085-42-1. Finer mesh ion exchangers are selected when higher resolution, improved contact efficiency or tighter packing in analytical and small-scale preparative columns is desired for separation and purification of anions. The Cl⁻-form and 200–400 mesh specification define the working particle range for controlled flow and exchange behaviour. Dowex® 1 X 2 from manufacturer Carl ROTH serves chromatography and ion-exchanger applications that call for a chloride-form resin at this mesh size. Documented CAS identity and pack format help laboratories standardise resin lots for method transfer and routine separations.
This article is part of Sorbents, silica gel & ion exchangers, in SPE & sample preparation.

Questions about Dowex® 1 X 2, 200-400 mesh, Cl--form, 100 g, plastic
What is this article?
Dowex® 1 X 2, 200-400 mesh, Cl--form, 100 g, plastic 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.
