Description
Bacteriological Petri dishes 120 x 120 mm are square culture dishes made of polystyrene (PS) for routine bacteriological and microbiological laboratory work. Measuring 120 x 120 mm, they provide a generous, flat growth surface suited to plating, streaking, colony isolation and visual assessment of cultures. The dishes are machine sterile and include ventilation to support controlled gas exchange during incubation. Clear polystyrene construction offers good optical clarity for inspecting colony morphology and medium appearance without opening the vessel. Each pack contains 20 pieces, a practical unit size for clinical, research and quality-control workflows. These square bacteriological Petri dishes from manufacturer Witeg align with standard incubator handling and shelf layouts used for culture dishes and related laboratory ware. The polystyrene material supplies the rigidity and transparency expected in everyday microbiology. With a pack net weight of 0,578 kg, the dishes are intended for single-use applications where consistent geometry, sterility and reliable ventilation matter for reproducible culture results.

Questions about Bacteriological petri dishes 120x120 mm
What is this article?
Bacteriological petri dishes 120x120 mm 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.
