Description
CHROMABOND flow control valve in brass is a chromatography accessory for regulating liquid flow in solid-phase extraction and related sample-preparation setups. The valve is chrome-plated with a matte finish and is supplied as a single piece, making it convenient as a spare or replacement part on CHROMABOND SPE hardware. Precise flow control at individual positions helps laboratories manage elution, washing and drying steps when several columns are processed in parallel. This component is part of the CHROMABOND accessory programme from manufacturer Macherey-Nagel and is intended for analytical laboratories that rely on robust metal valves for everyday SPE work. Net weight is 0,09 kg, so the unit is compact to stock beside manifolds and vacuum systems. Typical use includes environmental, food, pharmaceutical and general chemical sample preparation where brass flow valves support reliable solvent handling. The matte chrome surface gives a durable exterior suited to frequent handling on the bench while remaining compatible with standard CHROMABOND SPE configurations that require individual flow adjustment.
This article is part of SPE cartridges & columns, in SPE & sample preparation.

Questions about Chromab. valve, brass, 1 pcs.
What is this article?
Chromab. valve, brass, 1 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.
