Review on Prepoured Potato Dextrose Agar Plates by David Lesperance

These dishes arrived perfectly cast just like I made them myself. I no longer work in a large microbiology lab and use them for a hobby, so finding a source for ready-made, sterile agar petri dishes was a blessing. Less work for me! I kept these bowls in their shipping packaging in the fridge for a week to check for contamination, but NOT ONE. All utensils remained sterile. They're conveniently packaged in groups of five in a sealed plastic bag, so I only have to open five at a time. They went straight into my laminar flow chamber and were very easy to work with. Highly recommended!
