Petri Dishes & Culture Material

Petri dishes and culture plates are the working material of microbiology and cell culture. This subcategory comprises sterile disposable polystyrene Petri dishes in three diameters – 90, 60 and 35 mm – and a sterile flat-bottom 96-well cell culture plate. Dishes are supplied in cartons of 500, plates in cartons of 50.

The vented 90 mm dish is the standard format for microbiological testing. The vented 60 mm dish saves incubator space and suits screening work, while the 35 mm dish is meant for single-colony isolation and small cell culture experiments. The 96-well plate is TC-treated and therefore designed for cell attachment.

Typical applications

• Routine microbiological testing on 90 mm dishes
• Screening runs with many dishes where incubator space is limited
• Isolation of single colonies
• Adherent cell culture and test series in 96-well format

What to look for when buying

Choose the diameter by sample count and incubator capacity. The 90 mm dish offers the largest agar surface, 60 mm fits more dishes into the same incubator, and 35 mm is intended for small set-ups and single colonies. Vents keep a gap between lid and base so that air can circulate.

Mind the pack sizes: 500 dishes per carton are used up quickly in routine microbiology but take up a separate storage slot per diameter in smaller labs. The cell culture plate comes in smaller units of 50. If you pour your own media, a free sample lets you check beforehand that the format suits your workflow.
