Description
Buffer N4-EF is a wash buffer supplied as a 1000 mL bottle for laboratory sample-preparation workflows. Designed as Wash Buffer N4-EF, it supports intermediate washing steps in nucleic-acid purification and related molecular biology protocols where an N4-EF wash stage is specified. The ready-to-use liquid is filled in a bottle of 1000 mL and has a net weight of 1,19 kg, making it practical for routine bench use and bulk reagent stocking. Buffer N4-EF from manufacturer Macherey-Nagel is accompanied by GHS labelling (GHS02) with the signal word Warning and hazard statement H226, so standard laboratory precautions for flammable liquids apply during handling and storage organisation. According to the manufacturer description, the product is not classified as dangerous goods under transport regulations. Packaging volume and bottle format suit organised placement on reagent shelves alongside matching elution and redissolving buffers. Integrate Buffer N4-EF according to the instructions of the corresponding purification kit or method, and consult the safety documentation before first use to ensure correct personal protective equipment and workplace controls.

Questions about Buffer N4-EF (1000 mL)
What is this article?
Buffer N4-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 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?
