Description
Bacteriological Petri dishes 55 mm are polystyrene (PS) culture dishes intended for microbiological plating, colony isolation and related laboratory culture tasks. The 55 mm diameter offers a compact working area for solid media while remaining easy to handle in incubators and sterile workspaces. These dishes are gamma irradiated and supplied without ventilation, supporting closed incubation conditions where reduced gas exchange is preferred. Clear PS construction assists colony observation and routine counting. Pack size is 20 pieces, suitable for higher-throughput bacteriology benches, quality-control series and teaching practicals. Net weight is 0,096 kg per pack. Bacteriological Petri dishes from manufacturer Witeg provide a consistent disposable format for everyday culture workflows in clinical, industrial and research environments. The gamma-irradiated, non-vented design helps maintain aseptic integrity during storage and use, integrating smoothly into standard media-pouring, streaking and incubation routines without altering established laboratory procedures.

Questions about Bacteriological petri dishes PS
What is this article?
Bacteriological petri dishes PS is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Petri dishes, inside Culture media & microbiology, in Life Science & Microbiology.
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.
