Petri dishes you can autoclave and pour again.
This is a 500-dish case of reusable, autoclavable 90 x 15mm petri dishes, packed in sterile sleeves of 20. Use them straight from the sleeve the first time, then wash, autoclave and pour again. Disposable plates add up fast when you pour hundreds a month; these keep coming back through your workflow.
They are Microppose high-temperature polypropylene dishes with triple-vented lids, rated for standard 121 C (250 F) autoclave cycles at 15 psi. At 17 grams each they are thicker than typical disposables and resist cracking under heat.
High-temperature polypropylene handles 121 C / 15 psi cycles run after run.
Buy once and reuse instead of throwing plates away after every batch.
Each sleeve of 20 arrives sterile, so your first round needs no prep.
Mix LME agar powder with water in an autoclavable bottle and pressure sterilize it.
Let the agar cool until the bottle is comfortable to hold but the agar is still liquid.
Open one sleeve in front of a flow hood or in a still air box and pour about 18-20 mL per plate.
Let plates set with lids on, then stack upside down and seal with lab poly film.
Reusing them: after use, autoclave the plates to kill the culture, wash with mild detergent, rinse, then autoclave lids-on before the next pour. Polypropylene is a little less clear than polystyrene, which matters only for close photography.
Rather skip the pour?Our pre-poured MEA plates and Rapid Rhizo plates arrive ready to use. Browse everything in agar and isolation tools.
Yes. They are polypropylene rated for standard 121 C / 15 psi autoclave cycles.
Yes. Each sleeve of 20 is sterile from the factory, so the first pour needs no prep.
About 18 to 20 mL per 90mm plate gives an even layer that won't dry out too quickly.

I love the fact that I never have to buy petri dishes again! I throw my spent plates in the Dishwasher, then in my Presto Pressure cooker for 20 mins and they are like new! Zero contam!
1st time ever making agar and using petri dishes. These are nice and thick plastic petri dishes. Clear and I can see all the mycelium growing very easily
I have never seen this type before and thought I would try instead, for a little extra money you can really easily re-use these! They are very thick and have a completely different feel, as if they are unbreakable. The clarity is slightly more opaque but you can still see everything perfectly fine. I like the fact that I can sterilize them in a spawn bag and re-use if I want to.
