Description
Bacteriological Petri dishes 90 mm are disposable culture vessels made from polystyrene (PS) for routine microbiological plating and colony work. With a diameter of 90 mm, they offer a familiar working surface for streaking, isolation and media-based assays in research, clinical support and quality-control laboratories. The dishes are gamma irradiated and include ventilation to allow controlled gas exchange during incubation. Clear PS construction supports easy visual inspection of colonies and media without removing the lid. Each pack contains 500 pieces, making the format practical for high-throughput plating schedules and shared laboratory stocks. Net weight is 0,37 kg per pack. These bacteriological Petri dishes from manufacturer Witeg suit everyday culture applications across microbiology benches, tissue-culture support tasks and general cell-culture routines that rely on standard disposable plates. The 90 mm size is widely compatible with common incubators, colony counters and plate handlers used in academic, industrial and service laboratories. As single-use cultureware they help keep workflows clean when preparing agar plates, processing environmental or clinical samples, or incubating bacterial cultures under defined laboratory conditions.
This article is part of Petri dishes, in Culture media & microbiology.

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 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.
