Agar is where you clean up cultures, pick the strongest sectors and keep genetics true. We pour our plates fresh in our own clean room, machine-filled with 20 mL per 90mm dish, and stock the tools that go with them: sterile and autoclavable petri dishes, slants for storage, scalpels, agar punches and poly film for sealing.

Myco Labs Item #: AA32 -

    A standard liquid culture jar breathes passively through a filter disc, and oxygen runs short just as the mycelium needs it most. That's when cultures harden into dense clumps that clog the needle and inoculate unevenly. Active Air fixes that by pushing sterile, filtered air into the jar on a timer, so the mycelium stays fine, fluid and suspended. It's a shippable version of the bubbling setup we've run in our own lab for years, built from high-temperature parts that sterilize and reuse. 28...

        The Myco Lid Pro is our reusable liquid culture lid for standard wide-mouth mason jars. Instead of punching a needle through the same self-healing port over and over, you draw culture through a dedicated Luer Lock port, while a 0.45 micron syringe filter handles gas exchange. The lid stays on the jar from sterilization to the last syringe. The body is autoclavable Delrin (POM), the gasket rotates independently so the seal seats without twisting, and a raised pad on top gives you a clean place...

          Black MEA plates are malt extract agar infused with activated carbon, so white and light-colored mycelium stands out sharply against a deep black surface. The contrast makes it far easier to read growth edges, sectors and pigmentation, and to catch contamination early. Every plate is made in our clean room.

                  Agar slants are the long-term home for your best cultures. Each slant is a pre-poured test tube of malt extract agar set at an angle: transfer a clean piece of mycelium, let it establish, then refrigerate it. A colonized slant keeps a culture viable for up to 12 months, far longer than an agar plate, so your master cultures stay safe without constant replating. Every tube is a 15 mL polypropylene test tube of agar, light malt extract, potato dextrose and locust bean gum, pressure-sterilized,...

                              Common questions

                              How should I store pre-poured plates?

                              Keep them in the refrigerator and use them within 3-4 weeks for the best results.

                              Do I need a flow hood for agar work?

                              A flow hood is best, but a still air box works well for opening and inoculating plates.

                              Why use black agar?

                              The activated carbon makes white mycelium, sectors and contamination easy to see.

                              Are your plates made with antibiotics?

                              No. Our plates are made without antibiotics.
