Description
Buffer A4 Concentrate (25 mL) is a wash buffer concentrate for biochromatography laboratory workflows. Supplied as a 25 ml bottle, the concentrate is intended for preparation of 125 ml of ready-to-use Buffer A4 after dilution, giving a compact stock format for on-demand wash buffer. As a dedicated wash buffer component, it supports chromatographic washing steps in purification protocols that specify Buffer A4 and require reproducible buffer composition. The concentrate approach helps laboratories manage reagent inventory while still producing the full working volume needed for routine bench work. This product comes from manufacturer Macherey-Nagel within its biochromatography reagent offering. The 25 ml pack size suits lower-throughput runs, method set-up, and settings where large ready-to-use volumes are unnecessary. Net weight is 0,07 kg. Dilution of the entire concentrate yields the stated 125 ml of Buffer A4, aligning preparation with protocol requirements. Use standard laboratory handling practices for chromatographic wash buffers when diluting and applying the working solution in biochromatography applications.

Questions about Buffer A4 Concentrate (25 mL)
What is this article?
Buffer A4 Concentrate (25 mL) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Sorbents, silica gel & ion exchangers, inside SPE & sample preparation, in Chromatography equipment.
Loose sorbent, silica gel and ion-exchange resin are the phases bought in bulk to pack a column or to stir into a solution. Particle size and activity, or the ion-exchange capacity, are the specification. A TLC silica and a flash silica of different particle sizes are not the same separation.
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?
