Description
BioFix Lumi freeze-dried luminous bacteria are specialised reagents for acute toxicity testing in environmental analysis according to DIN EN ISO 11348-3. This pack contains 20 tubes of freeze-dried luminous bacteria including reconstitution solution, allowing active suspensions to be prepared immediately before luminometric measurement. Special packing in cooling bags supports cold-chain integrity from delivery through laboratory storage. The bacteria are used in standardised bioluminescence assays to assess the inhibitory effect of water, wastewater and aqueous extracts on light emission, providing a recognised biological endpoint for environmental monitoring and quality control. From manufacturer Macherey-Nagel, the freeze-dried presentation eases handling and logistics compared with continuously maintained cultures while remaining compatible with established ISO 11348-3 methods. The 20-tube format suits laboratories with higher sample throughput in environmental test-kit workflows; net weight is 0,72 kg. Proper reconstitution restores the metabolic activity required for reliable light-output readings in toxicity screening.
This article is part of Reference substances & reagents (other), in Analytical standards & reference materials.

Questions about Lumin.bacteria, 20x20
What is this article?
Lumin.bacteria, 20x20 is the article on this page. Luminix Health distributes Macherey-Nagel 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.
