Description
CHROMABOND flow control valves in brass are compact chromatography accessories intended for regulating liquid flow during solid-phase extraction and related sample-preparation steps. The valves are manufactured from brass with a chrome-plated, matte finish, giving a durable metal surface suited to routine laboratory handling. Supplied as a pack of 12 pieces from manufacturer Macherey-Nagel, they complement CHROMABOND column systems used for extraction, clean-up and elution workflows. Operators can integrate the valves into existing SPE setups to manage solvent and sample streams with straightforward mechanical control. The robust construction supports repeated use in analytical environments such as environmental, food or pharmaceutical laboratories where consistent flow adjustment is required. Their small format simplifies storage alongside columns, adapters and other chromatography consumables. As dedicated CHROMABOND accessories, these brass flow control valves help maintain orderly, reproducible sample-preparation sequences without complex additional hardware.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. valves, brass, 12 pcs.
What is this article?
Chromab. valves, brass, 12 pcs. 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.
