Description
Buffer A4 Concentrate (200 mL) is a wash buffer concentrate designed for biochromatography applications. The product is supplied in a 200 ml bottle and is intended for dilution to prepare 1000 ml of ready-to-use Buffer A4, offering an efficient concentrate format for medium-scale wash buffer demand. It serves as a wash buffer component in purification workflows that call for Buffer A4 and benefit from consistent buffer preparation. Laboratories can store the concentrate and generate working solution when needed, supporting flexible reagent logistics without holding large volumes of diluted buffer. Offered by manufacturer Macherey-Nagel as part of its biochromatography reagent range, this concentrate fits established protocols that specify Buffer A4 wash steps. The 200 ml pack size balances bench convenience with higher working volume after dilution, making it suitable for regular laboratory throughput. Net weight is 0,35 kg. Full dilution of the concentrate produces the indicated 1000 ml of Buffer A4. Apply standard laboratory practices for handling and diluting chromatographic wash buffers when preparing and using the working solution in biochromatography procedures.

Questions about Buffer A4 Concentrate (200 mL)
What is this article?
Buffer A4 Concentrate (200 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.
