Acids

The grade is in the product title. "Pure" and "extra pure" suit general lab work, cleaning and synthesis, such as nitric acid, extra pure, 250 ml. For quantitative analysis choose p.a. or ISO grade, for example sulphuric acid, p.a., ISO, 1 l. Pharmacopoeia methods call for Reag. Ph. Eur. grades. For ICP and other trace-metal work, use acids made for trace analysis at ppb level, such as hydrochloric acid for trace analysis, 2.5 l. Not sure which grade your method needs? Ask sales@luminixhealth.com.

Concentrated acids are the starting point for digestions, synthesis and making your own dilutions. Always add acid to water, never the other way round, and work in a fume hood. Many methods instead call for a defined dilution, such as hydrochloric acid diluted R2, Reag. Ph. Eur., 1 l, which saves preparation time. For titration you need an exact molarity with a stated titer, for example nitric acid volumetric solution 1.0 mol/l, 1 l. More titrants are in volumetric standard solutions.

Most mineral acids are supplied in glass, which is inert to them; the packaging is stated in the product title, such as nitric acid, extra pure, 250 ml, glass. Plastic packs are lighter and do not shatter, which helps with larger volumes and transport. Hydrofluoric acid is the exception: it attacks glass, so never store or handle it in glass vessels. Use only plastic labware for HF, for example with hydrofluoric acid, ACS, ISO, 1 l, and keep calcium gluconate gel at hand. Questions on packaging: sales@luminixhealth.com.

Concentrated acids are dangerous goods; the UN number is in the product data, for example UN 2031 for nitric acid, extra pure. That can affect transport options and delivery time, so ask us before you plan a large order: sales@luminixhealth.com. Store acids in a ventilated acid cabinet or in a drip tray, below eye level, and keep them away from bases, organic solvents and metals. Oxidising acids such as nitric acid belong apart from flammables. Always check the hazard pictograms and the safety data sheet before opening a bottle.

An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.

An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
