Description
Buffer BW is a wash buffer supplied in a 500 ml bottle for laboratory purification and biochromatography applications. As Wash Buffer BW, it is used in intermediate wash steps to remove contaminants while the target remains bound, helping maintain method consistency across sample batches. The formulation is a 2-propanol-containing solution and is transported as a flammable liquid under UN 1993, requiring appropriate solvent storage and handling on the bench. The larger 500 ml pack size supports higher-throughput work, shared reagent stations and frequent kit replenishment, with a net weight of 0,70 kg. Provided by manufacturer Macherey-Nagel, this non-sterile laboratory buffer fits standard molecular biology and chromatography wash protocols that specify Buffer BW. Signal word and hazard statements indicate flammability and irritant properties; laboratory staff should review safety measures before opening the bottle. The 500 ml format offers an efficient balance of working volume and shelf convenience for routine wash-buffer demand in sample-preparation workflows.

Questions about Buffer BW (500 mL)
What is this article?
Buffer BW (500 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?
