My son found a science experiment on the internet he wanted to do, which was which types of gum affect bacterial growth. The experiment required petri dishes, which we did not have. And to be honest, I had no idea where to find them.
On a hunch, I checked Amazon, which amazingly, had them, and had many of them. We had to choose between mix your own, vented, unvented and other variations, all of which we knew nothing about. After some quick internet research, decided to go with "vented" (which basically means that the lids are bigger than the bottoms), and this pack with sterile cotton swabs (to avoid accidental outside infections) seemed like a good choice. The fact that it could be delivered in two days with Amazon Prime sealed the deal.
Suffice to say, we did the experiment, and while the results of the experiement were somewhat inconclusive, the school liked it and my son won 2nd place in his grade for this experiment, which was great!
With respect to these plates and swabs, the quality is good, but not terrific. Thinking back to my school days, we had glass plates, but it doesn't really make economic or safety sense to use glass in science experiments these days. The agar worked, we found bacteria, but be sure to read the directions. It helps to give your bacterial at least 2-3 days to grow AND to keep them in a room that's about 85 degrees. While this is hard (expensive) to do in the winter, we put these things in the boiler room and then put a space heater in there for good measure. Keeping the door closed for a full day, it held the temperature rather well, and seeing the bacterial growth was pretty cool.
So all in all, I'd say these do what they are supposed to do. They may not be the absolute best lab quality, but they are rather good quality and work well. We gave the left over dishes to the school and they were very happy with them.
Hope this helps you in your purchasing decision.

BIOTECH QUALITY AND BEST RATEDFactory-direct fresh 10 100-mm pre-poured sterile LB-agar plates, 10 sterile 6-inch long swabs (in 5 pouches), 2 culture tubes and 2 transfer pipets. Our plates are manufactured in the USA using the biotech GMP standards. Each plate has a fresh and thick layer of agar. Fresh plates promote faster and more bacterial growth as compared to aged stored plates. Re-sealable packaging is convenient for re-use. |
THE SAFEST PLATES FOR STUDENTSNot all agar plates are made with the same nutrient formula. The LB agar plates in the EZ Bacteria Science Kits are the safest for kids/students to use in school or at home. LB agar plates support the growth of non-fastidious bacteria while the other agar plates such as TSA plates and blood agar plates allow the growth of more dangerous semi-fastidious and fastidious bacteria, respectively. We recommend that you check the ingredients of the agar plates from the other sellers. Learning science is fun, but the safety of students is more important. |
LIVE EXPERT CONSULTATIONAny questions? No worry. Inside the kit, you will find a toll-free number that you can call in case you have a question about the product. You will receive immediate live support from PhD scientists with extensive hands-on experience. Before you buy or try, check out the vendor to see whether it has a telephone number or just an email address. You do not have to wait for the email which may or may not come in time for your experiments. |

Already growing
Ordered from here before with good results, however this time the plates arrived with several already growing. The agar is obviously good, but my classroom could only do a portion of our planned experiments.
