Petri Dishes
How to choose petri dishes
Sub-type match
Decide sub-type first: Science & Laboratory fits culture work, Business & Industrial fits pans, Laboratory Supplies covers general items.
Material tradeoff
Material decides reuse: stainless steel for repeat use, plastic or paper for discard, copper or lead for decorative only.
Colour choice
Colour is limited to white or purple, both on plastic, so pick purple if you want sample contrast.
Craft vs lab
Alcohol ink, copper, and lead sit outside functional lab use, so avoid them for experiments.
Wet or dry
If you need a dish that survives moisture, stainless steel beats paper, which suits dry tasks only.
What's good
- Science & Laboratory plastic petri dishes give a sterile, disposable base for cultures, ideal for classrooms and hobbyists.
- Business & Industrial stainless steel trays provide a rigid, reusable surface that handles repeated weighing without bending.
- Laboratory Supplies paper dishes offer a featherweight option for dry sampling, useful when you want zero clean-up.
- White or purple plastic colours let you pick background contrast, helping spot colonies or residues faster.
Things to watch
- Plastic dishes are single use, so a busy lab will bin many after one session, which wastes material.
- Stainless steel pans need scrubbing and drying after each use, unlike the throwaway plastic type.
- Copper and lead pieces are dense and chemically active, making them wrong for any living sample or food contact.
- Alcohol ink items serve only as decor, so they disappoint buyers expecting real laboratory function.
Care & maintenance
Stainless steel care
Wash stainless steel dishes in mild soap, then dry completely to prevent water marks.
Disposable types
Dispose of plastic and paper types after they touch agar, chemicals, or powders.
Metal decor
Store copper or lead craft pieces in a dry cupboard to slow surface change.
Ink surfaces
Dust alcohol ink displays with a clean cloth, avoid harsh cleaners.
