Got this agar to use in my mycoligy Petri dishes. It works very well! It's very easy to mix and use, with instructions clearly printed on the bottle. You get a lot in each order and it's great quality agar. Definitely recommend!!

lo que esperaba

In the past, I've used Evviva Science's nutrient agar, and had good success, though I've mainly switched over to another supplier that has more formulations. However, I did like their product, so I thought I'd try their TSA agar.A couple of things; First, if you don't need to cultivate fastidious organisms, just go with their nutrient agar, as I believe it is cheaper. The second is that I currently don't have any pure cultures with which to test that this is indeed TSA; however, given my past positive experience with the company, I don't think they're likely to skimp on the formulation.I mixed up a small batch of this, as well as some Sabaroud dextrose agar for a little cultivation experiment (I thought about doing a head-to-head comparison with nutrient agar, but decided against it). Mixing was straightforward; it dissolved well in boiling water. It took 4g to make 100mL of agar, which was enough to fill 4 small and 2 large Petri dishes (the small ones are for growing lawns, the larger are reserved for streaking to isolation later). (As an aside, the large-print directions right on the bottle are easy on my presbyopic eyes!) After pressure-cooking and letting cool, the agar set well and was easy to inoculate.I don't have results yet, but I had no problem mixing and pouring the plates, and if there's an issue it's probably more my rusty technique than the fault of Evviva.

I am impressed with this tryptic soy agar. The price is quite competitive, making it an excellent choice. I decided to pour some plates myself and I found the set up to be very convenient. The agar dissolved perfectly, which made the process even easier. For a few plates, I used 4 grams of agar to make 100 milliliters of solution, and the results were fantastic.

Ideally, a person would buy petri dishes with pre-mix, but around here, culturing is more of a hobby than an industry, so this was a good value to make many, many, many culture plates.No issues mixing, and makes a good bed for all kinds of crud to grow and show itself.Really fun paired with a microscope to investigate what's growing around you.
