Description
PE Filter Elements ROTI®XBond are polyethylene frits intended for empty solid-phase extraction (SPE) columns with a 20 ml capacity. Each element has a thickness of 2,5 mm, a diameter of 19,7 mm and a pore size of 20 µm, giving a defined geometry for retaining sorbent beds while permitting solvent and sample flow. Packaged as 100 pc(s), they support laboratory workflows in which empty SPE columns are packed in-house for method development or routine sample clean-up. These accessories form part of the ROTI®XBond range from manufacturer Carl ROTH and suit chromatography setups that require consistent frit dimensions matched to 20 ml column formats. Typical uses include analytical and preparative SPE, where reliable packing retention and reproducible flow behaviour are essential. The pack weight is 0,500 kg. By combining PE construction with a 20 µm pore structure, the elements help maintain bed integrity during conditioning, loading, washing and elution steps common in solid-phase extraction protocols.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about PE Filter Elements ROTI®XBond, for Empty SPE Columns 20 ml, 100 unit(s)
What is this article?
PE Filter Elements ROTI®XBond, for Empty SPE Columns 20 ml, 100 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in SPE cartridges & columns, inside SPE & sample preparation, in Chromatography equipment.
An SPE cartridge holds a bed of sorbent. Bed mass, sorbent chemistry and volume are the specification. A 100 mg C18 cartridge and a 1 g C18 cartridge take different sample loads and different elution volumes. The method names all three.
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 SPE cartridges & columns. The catalogue is Chromatography equipment.
