In this Science Buddies science project, you will test several disinfectants to see which ones work best to decontaminate the surface of a cutting board. You can customize this kit to include the nutrient agar plates, cotton balls, dissecting forceps, and other supplies needed to complete this experiment.

Rated 5 out of 5 by from Great for science fair Ordered these for son's 8th grade science fair project. Arrived exactly at time promised. Stored in refrigerator until ready to use. Plate inoculation was easy. Incubated in basement. Grew beautiful (actually disgusting!) specimens in a few days. Son was amazed and fascinated. Science fair conquered!!

Rated 4 out of 5 by from Easy to use and perfect for student micro projects Trying to teach students the proper method for making agar dishes can be difficult. At times when they make their own the agar is lumpy and uneven, making it difficult to observe. The only suggestion I would make is order more than you need because the plastic on the dishes is fairly thin and on every purchase I have made, typically at least one dish is cracked and cannot be used. Other than that these are so much easier than preparing your own.

Rated 4 out of 5 by from Practical but some plates were damaged. I used these plates for my after school program. They worked very well. Just a couple of things to keep in mind if you are considering buying it. 1) the only option of shipping is 2-day, so that will add up to your total. 2) out of the 3 packs I used, 3 plates were unusable: one had a crack, one had some unidentified object in the agar, and one was contaminated. However, overall is a good product.

Rated 5 out of 5 by from Agar plates used in Elementary class Only one of my 120 plates showed contamination. The plates are wrapped in small stacks of ten and double boxed for shipping. No breakage in my order. They are easy to use and store. I appreciate that shipping charges are stated upfront. Several other suppliers offer lower rates per plate cost but ridiculously expensive shipping. I trust Carolina to deliver on time and they did. Used for 5th grade handing washing experiment, Q1 positive control- dirty thumb, Q2 thumb washed with water, Q3 thumb washed with soap & water, Q4 negative control - no treatment. Fabulous results!

Rated 4 out of 5 by from This product was great. When the Petri dishes came, they were soaking wet and had an awful stench to them. However, they worked really well. they came right on time in the mail.
