Description
CHROMABOND PTL columns are solid-phase extraction columns intended for solvents that are lighter than water. With a column volume of 30 mL, they support phase-separation and sample-handling steps in chromatographic sample preparation where the organic solvent floats on the aqueous layer. These CHROMABOND columns from manufacturer Macherey-Nagel are supplied as empty or dedicated PTL-format tubes for laboratory workflows that require reliable collection or separation of lighter-than-water solvents. The 30 mL capacity suits larger sample or solvent volumes typical of preparative clean-up and extraction sequences. Packaged in units of 100 pieces, the columns offer a practical stock quantity for routine analytical and research laboratories. As chromatography accessories, PTL columns integrate into standard SPE and solvent-handling procedures without altering established method layouts. The defined 30 mL format helps maintain consistent handling when working with biphasic systems in which the organic phase is less dense than water, supporting clear laboratory organisation around solvent density differences.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. columns PTL, 30 mL
What is this article?
Chromab. columns PTL, 30 mL is the article on this page. Luminix Health distributes Macherey-Nagel 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.
Shelves beside this one are Sorbents, silica gel & ion exchangers and Flash, empty & glass chromatography columns.
What should I check before I order?
