Description
Buffer PW1 is a laboratory wash buffer supplied in a 1000 ml bottle for workflows that require Wash Buffer PW1. This larger pack supports extended washing steps in biochromatography and general laboratory purification procedures where a dedicated PW1 buffer is specified. The product is based on a 2-propanol solution and is classified for transport as UN 1993, flammable liquid, n.o.s. (2-propanol solution), packing group III. Associated hazard information includes the signal word Attention, statements H226, H302, H315, H319 and H336, and GHS labelling GHS02 and GHS07. With a net weight of 1,24 kg, the 1000 ml bottle from manufacturer Macherey-Nagel suits higher-throughput benches and shared reagent stations. Laboratory staff should observe flammable-liquid precautions, including adequate ventilation and control of ignition sources, in line with the safety data. The ready bottle format simplifies dispensing and helps maintain consistent wash conditions across repeated sample-preparation runs that call for Buffer PW1.
This article is part of Buffers (other), in Buffers & pH solutions.

Questions about Buffer PW1 (1000 mL)
What is this article?
Buffer PW1 (1000 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.
