Description
Chromatography column, 20 ml, porosity 4 is a precision laboratory glassware component intended for chromatographic separations and sample preparation. Manufactured from borosilicate 3.3 glass, it features an integrated VitraPOR® filter plate measuring 10 mm in diameter with porosity grade 4, ensuring controlled particle retention and consistent flow. The working height above the filter plate reaches 300 mm, offering sufficient column bed volume for packing stationary phases or adsorbents. This column from manufacturer ROBU - Stereon is supplied in practical multi-packs and supports gravity-driven or low-pressure chromatography workflows commonly performed in analytical, preparative and research laboratories. The chemically resistant borosilicate construction withstands typical organic solvents and aqueous buffers used in method development and routine analysis. Its defined porosity and filter geometry contribute to reproducible elution profiles, making the column suitable for educational settings as well as professional quality-control environments where reliable glass chromatography hardware is required.
This article is part of Flash, empty & glass chromatography columns, in SPE & sample preparation.

Questions about Chromatography Column, 20 ml, Por. 4
What is this article?
Chromatography Column, 20 ml, Por. 4 is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Flash, empty & glass chromatography columns, inside SPE & sample preparation, in Chromatography equipment.
A flash column or an empty glass column is the tube a separation is packed or run in, under gravity or under air pressure. Diameter and length, and whether it arrives prepacked, are the choices. An empty column still needs a frit and a sorbent.
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 Flash, empty & glass chromatography columns. The catalogue is Chromatography equipment.
Shelves beside this one are SPE cartridges & columns and Sorbents, silica gel & ion exchangers.
