Description
Petri dishes with a diameter of 40 mm and a height of 12 mm are compact glass culture dishes supplied with lids for microbiological plating and related laboratory work. Marketed under the Anumbra designation, they are produced bubble-free and streak-free so that colony morphology and culture surfaces remain clearly visible during inspection. The shallow 12 mm profile suits standard agar layers in small-format assays, spot tests and space-efficient incubator loading, while the matching lid helps limit contamination and moisture loss during incubation. Each dish has a net weight of 0,019 kg. Packs contain 18 pieces and are suitable for routine bacterial isolation, fungal growth studies, teaching laboratories and general cell- or tissue-culture workflows where a small footprint is preferred. These glass Petri dishes from manufacturer Witeg provide a practical, optically clean format for everyday culture tasks without unnecessary bulk. The 40 mm diameter keeps reagent and media consumption low, making the dishes convenient for screening series, parallel replicates and educational demonstrations that require consistent, transparent glassware.

Questions about Petri dishes Ø: 40 mm h: 12 mm
What is this article?
Petri dishes Ø: 40 mm h: 12 mm is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Petri dishes, inside Culture media & microbiology, in Microbiology lab supplies.
A Petri dish is the shallow lidded plate agar is poured into, or a sample is placed in. Diameter and whether it is vented, and whether it arrives sterile and empty or already filled, are the choices. A 90 mm dish is the ordinary one. Slippable lids and vented lids differ in how they dry a plate.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
