Description
Buffer AW is a wash buffer supplied in a 3000 mL bottle for biochromatography and laboratory reagent applications. Formulated as a 2-propanol-containing solution, it is classified as a flammable liquid, n.o.s. (UN 1993, Class 3, packing group III) and requires the usual controls for flammable organic solvent mixtures on the bench and in storage. The buffer is intended for wash steps in purification workflows where bound material is rinsed under defined solvent conditions before elution. From manufacturer Macherey-Nagel, the large 3000 mL pack supports higher-throughput or multi-user settings that benefit from extended reagent supply and fewer changeovers. Net weight is 3,80 kg per bottle. Labelling carries the signal word Attention together with GHS flammable and acute-hazard pictograms; hazard statements address flammability, harmful if swallowed, skin and eye irritation, and possible drowsiness or dizziness. Close containers after use, keep away from heat and ignition sources, and apply the listed precautionary measures during handling. This bulk wash buffer format fits methods that specify Buffer AW for standardised wash operations in the laboratory.
This article is part of Buffers (other), in Buffers & pH solutions.

Questions about Buffer AW (3000 mL)
What is this article?
Buffer AW (3000 mL) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Buffers (other), inside Buffers & pH solutions, in Lab chemicals.
These are buffer solutions and salts that are not a pH calibration standard and not a named biological buffer. The pH, the concentration and the identity of the ions are the specification. A buffer has a capacity. Diluted too far, it is only salty water.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
Which category should I open next?
