Since we broke the 15g down into smaller lots, we ended up adding nutrients by weight. Most folks don't have a scale for this, so my best guess would be 1 Tablespoon of beef or chicken bullion plus 1 Tablespoon of sugar for the entire 15g package. If all else fails, you can substitute plain Knox gelatin for the agar. But, gelatin is not stable at room temperature and especially not in an incubator (it melts after a while into goo). You'll be forced to leave the Knox gelatin experiment in the fridge. Even in that cold environment, some bacteria will grow. **Q: What is the shelf life of the pocket open and unopened? Should I I store this with desiccant packs?** A: I’ve had the first packet for close to a year and half without any issues after opening it. I would rather put a box of baking soda by the bag rather than put desiccant packets in there. I only say this because so much as sticking your hands in there can potentially compromise the integrity of the product. **Q: Is this good for making a salt bridge?** A: Hello, yes, this is good for making a salt bridge. **Q: My bacteria is not growing. I have used 12 sterilized Petrie dishes and distilled water. It has been several days. Why is this medium not working?** A: This product is only agar- it does not have the nutrients that microorganisms need to grow. This product is used to make water set up as a gel but you will need to add some beef boullion & sugar (or other nutrients if you are looking for specific bacteria) if you want to grow microorganisms. You could also purchase a product called NUTRIENT AGAR which already has the nutrients mixed with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works well for petri dish prep *by M***A on March 21, 2024* works well for petri dish prep.

It was for a simply homeschool project on fermentation. The agar was easy to mix and set up nicely. I will buy it again for our next project! ### ⭐⭐⭐ Not Nutrient Agar *by A***K on December 31, 2013* We learned the hard way this agar won't grow much of anything without adding some nutrients. After three experiments, with a total of 30 petri dishes, it grew nothing. We contacted our child's teacher who informed us we probably bought just the agar (gelatin). We used the remaining powder, seasoned with some bullion and sugar, and all 20 petri dishes grew fantastic colonies within a few days. The agar, itself, is actually of very good quality. It didn't dissolve in the incubator as regular gelatin did. I measured out five portions of 3 grams each which I mixed with 200ml of distilled water. This is enough to fill ten 80-100mm petri dishes with about 1.5 tablespoons of agar. Be sure to bring it to a boil, or it won't set. You could actually make the entire 15 gram package of agar with 1 liter of water and refrigerate the portion you didn't use. The agar will return to a liquid when heated. ## Frequently Bought Together - Agar Agar Powder - 15 grams, Laboratory Grade - Sterile Plastic Petri Dishes Set, 50 Pcs Blank Microscope Slides, 100 Pcs 20x20mm Square Cover Glass, 5 Pcs 90mm Diax15mm Deep Lab Petri Plate Dish with Lid and 10 Test Pipette Droppers - Organic Light Dried Malt Extract DME - Maltoferm 10001-1 Lb --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/1725067-agar-agar-powder-15-grams-laboratory-grade](https://www.desertcart.ph/products/1725067-agar-agar-powder-15-grams-laboratory-grade) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-23*
