Description
Buffer N3-EF is a wash buffer supplied as a 1000 ml bottle for laboratory purification and sample-preparation workflows that include a defined wash step. This ready-to-use reagent is intended to support removal of unbound material or residual contaminants while preserving target components on columns or related matrices. The 1000 ml pack size suits regular bench use and multi-run protocols in molecular biology and analytical laboratories. Buffer N3-EF from manufacturer Macherey-Nagel is positioned within the laboratory materials category and is specified as wash buffer N3-EF for integration into established multi-step methods. The unit has a net weight of 1,21 kg and is delivered non-sterile for general laboratory application. The manufacturer description notes that the product is not classified as dangerous goods under transport regulations, facilitating straightforward shipping and stock handling. Laboratories can apply Buffer N3-EF wherever method instructions call for this wash buffer between equilibration or binding and subsequent elution stages. Use the bottle in accordance with the safety data information and local laboratory practice to maintain reliable performance throughout routine processing.

Questions about Buffer N3-EF (1000 mL)
What is this article?
Buffer N3-EF (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 Produits chimiques de laboratoire et industriels.
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?
The category is Buffers & pH solutions. The sub-category is Buffers (other). The catalogue is Produits chimiques de laboratoire et industriels.
Shelves beside this one are pH buffers & conductivity standards and Biological buffers (Tris, HEPES, MOPS).
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
