Description
Bacteriological Petri dishes 140 mm are large-format culture vessels manufactured from clear polystyrene (PS) for microbiological and bacteriological applications that need extra surface area. The 140 mm diameter supports broader plating layouts, denser colony distributions and media volumes that exceed standard 90 mm plates, which is useful in screening, environmental monitoring and teaching laboratories. These dishes are supplied without ventilation and are machine sterile, ready for controlled culture workflows where a closed dish geometry is preferred. Clear PS allows straightforward observation of growth and media appearance during incubation. Pack size is 10 pieces, with a net weight of 0,486 kg per pack. Bacteriological Petri dishes from manufacturer Witeg in this 140 mm format fit culture-dish, tissue-culture support and cell-culture laboratory categories that call for robust disposable PS plates. The larger footprint remains compatible with many standard incubators and handling routines used in industrial, academic and service settings. As single-use ware they help maintain clean plating practices when preparing agar media, spreading samples or incubating bacterial cultures under laboratory conditions that benefit from a wider working surface.

Questions about Bacteriological petri dishes Ø 140 mm
What is this article?
Bacteriological petri dishes Ø 140 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.
