Description
Platinum wire, min. 99,95 %, diameter 2 mm is a high-purity noble-metal reagent wire supplied in a 5 cm length for analytical and qualitative laboratory work. With empirical formula Pt, CAS number 7440-06-4 and EG nr. 231-116-1, the material is characterised by a molar mass of 195,08 g/mol, density of 21,45 g/cm³ and boiling point of 3827 °C, supporting demanding thermal and chemical environments. The 2 mm diameter provides a robust cross-section suitable for flame tests, electrode contacts, micro-scale heating elements and cation detection procedures where inertness and conductivity are essential. Packed in plastic for secure handling, this short length from manufacturer Carl ROTH is convenient for method development, teaching demonstrations and small-scale analytical setups without excess inventory. Laboratories use platinum wire of this grade when reproducible surface behaviour and resistance to oxidation are required in qualitative inorganic analysis and related detection workflows.
This article is part of Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about Platinum wire, min. 99,95 %, diameter 2 mm, 5 cm
What is this article?
Platinum wire, min. 99,95 %, diameter 2 mm, 5 cm is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Lab chemicals.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
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.
