Petri Dishes
Sterile disposable Petri dishes for microbiology, cell culture and quality control.
Disposable Petri dishes are the standard vessel in microbiology. Media are poured into them, samples streaked out and colonies incubated and counted. Clinical, food and pharmaceutical laboratories and production quality control use them in large numbers, because sterile disposable dishes replace washing and sterilising glass dishes.
The catalogue lists the disposable Petri dish in the standard 90 mm size. It is made of optically clear polystyrene so colonies are easy to see, and has vents in the lid that allow gas exchange during incubation. The dishes are gamma sterilised and packed 20 to a sleeve, which makes low-contamination handling easier.
Typical applications
- Bacterial and fungal cultures in microbiological diagnostics
- Environmental monitoring with settle plates in production and cleanrooms
- Colony counts in quality control
- Teaching and training laboratories with high dish usage
What to look for when buying
Check diameter and venting first. 90 mm is the most common size for routine cultures. The dish in this sub-category has vents in the lid and is gamma sterilised.
Packaging matters too: the dishes come 20 to a sleeve, and the minimum order is 500. Sterile Petri dishes with 60 mm and 35 mm diameters are listed in the Laboratory & Diagnostics department; you can request unvented dishes or contact plates in your enquiry.
Frequently asked questions
Are the Petri dishes sterile?
Yes, they are gamma sterilised and packed in sleeves of 20.
What are the vents in the lid for?
They keep a small gap between lid and base, allowing gas exchange during incubation.
Are other diameters available?
This sub-category lists the 90 mm size. Sterile 60 mm and 35 mm Petri dishes are listed in the Laboratory & Diagnostics department.
