Description
Buffer PW2 Concentrate is a wash buffer concentrate supplied in a 200 ml bottle and intended for preparation of 1000 ml ready-to-use Buffer PW2. It is used in laboratory nucleic acid purification and related molecular biology workflows where a defined wash step is required after lysis and binding. Once diluted according to the working protocol, the concentrate yields a full litre of wash buffer, supporting consistent handling across multiple sample preparations. The bottle format has a net weight of 0,35 kg and is suited to routine bench use in research and diagnostic laboratories. Offered by manufacturer Macherey-Nagel, this PW2 concentrate integrates into established purification buffer systems without requiring additional formulation work beyond dilution to the stated working volume. The concentrate packaging reduces bulk compared with pre-diluted buffer while still delivering sufficient material for one litre of finished wash solution. It is intended for professional laboratory use only and supports efficient inventory planning in molecular biology and sample-preparation environments that rely on standardised wash buffers.
This article is part of Buffers (other), in Buffers & pH solutions.

Questions about Buffer PW2 Concentrate (200 mL)
What is this article?
Buffer PW2 Concentrate (200 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.
