Description
Petri dishes measuring 120 x 20 mm are classic glass culture vessels for microbiological plating, colony isolation and cell-culture work. Manufactured from soda-lime glass of the 3rd hydrolytic class, these dishes from manufacturer Marienfeld are free from cadmium and lead and feature particularly flat inner surfaces on both base and lid for even media distribution and clear observation. They are sterilisable up to 121 °C, allowing reliable autoclave reprocessing between uses. Supplied in cartons of 72 pieces, the pack supports routine high-throughput laboratory workflows. The 120 mm diameter offers generous working area for streaking and counting while the 20 mm height accommodates standard agar volumes. These reusable glass Petri dishes provide a durable, optically clear alternative to single-use plastics for laboratories seeking consistent performance and reduced consumable waste. Suitable for bacteriology, mycology and general culture applications requiring dimensional accuracy and chemical inertness.
This article is part of Petri dishes, in Culture media & microbiology.

Questions about Petri dishes 120x20 mm,
What is this article?
Petri dishes 120x20 mm, is the article on this page. Luminix Health distributes Marienfeld 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.
