Description
Celite® 545 from Carl ROTH is a filter aid formulated on a silicate basis with the CAS registry number 68855-54-9. It acts as an effective sorbent for column chromatography, enabling reliable filtration steps in analytical procedures. The silicate composition creates a stable matrix that supports consistent performance during separation techniques commonly employed in research and testing facilities. This grade promotes reproducible results, which proves essential for maintaining accuracy in routine laboratory workflows. Physical characteristics remain suitable for handling in controlled environments, contributing to streamlined processes in chemical analysis. Laboratories depend on such materials to enhance efficiency in purification tasks and isolation methods. The product supports diverse applications requiring solid-phase supports without introducing variability. Its design ensures compatibility with established protocols in scientific settings focused on high-quality outcomes. aligns well with typical consumption rates observed in analytical laboratories conducting regular experiments.

Questions about Celite® 545, filter aid on silicate basis, 250 g, plastic
What is this article?
Celite® 545, filter aid on silicate basis, 250 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.
