Yuantide Bio Lab-Grade 100% Agar Agar Powder,150g / 5oz, Nutrient-Free, Petri Dish Solidifying Agent, Gel Strength 700g/cm2, for Mycology and Lab Research

The instructions were clear and a middle school leveled student pulled off an experiment flawlessly with the gel. She used brown rice water to help set the gel so that way there are nutrients the bacteria can live off of. I won’t lie, it seemed like it could have been too much but I’m highly impressed with how durable and high quality it turned out. Great value for your money as we only used a small portion of the powder so far, not even a 1/4 of it gone and 12 dishes were filled and successfully yielded bacterial growth after swabbing. There was no strong smell either so that was a plus.

Works well, directions are simple. Makes a very solid structure, and reasonably clear.

It's a simple product, but I've had bad Agar before. All you have to do is follow the simple recipe on bottle and your plates will be perfect every time. I use brown rice for grain spawn, so after I do the 2 minute boil on the rice I literally just take the rice water and mix it with the Agar Agar and I get the strongest, healthiest plates I've ever seen. Simple, fast and efficient.

Used to make nutrient agar plates for middle school science bacteria swab lab. Works like a charm.

works as it should. I'm new to mycology and this was recommended to me and I'm happy with the product.

Easily enough powder to make 100 if not more petri dishes. Glad I bought the scientific grade.

Works for what I need it for and is a good buy compared to others on Amazon

This does seem to be pure agar agar powder. It mixes well and sets on the petri dishes as would be expected. It is, however, pure agar agar--which means it's usually necessary to mix it with my own solution of peptones, sugars, starch or other culturing medium in order to use it. I prefer it this way since it allows me to formulate my own concentrations for different uses. It's a good amount, will fill a lot of dishes.
