Description
McFarland BSS 0,5 is a ready reference standard prepared for microbiology workflows that rely on controlled turbidity comparison. Supplied as one tube unit, it supports routine adjustment of microbial suspensions to a defined McFarland level before inoculation, susceptibility testing, or culture work. Physical data include a density of 1,01 g/cm³ and a boiling point of 100 °C, consistent with an aqueous laboratory standard used at the bench. In environmental and water-analysis settings it is equally useful wherever turbidity measurement underpins sample preparation or method control. The preparation comes from manufacturer Carl ROTH and is intended for laboratory use in applications such as water and wastewater analysis as well as general microbiological density matching. Presented as a single-piece tube format, it integrates easily into standard McFarland comparison procedures without additional reconstitution steps. Clear labelling and compact packing help keep reference material organised beside spectrophotometers, densitometers, or visual comparison cards in teaching, QC, and routine diagnostic laboratories.
This article is part of Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about McFarland BSS 0,5, for microbiology, 1 unit(s), tube
What is this article?
McFarland BSS 0,5, for microbiology, 1 unit(s), tube 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.
