Agar serves as a crucial gel growth medium for fungal research. When combined with water, heated, and cooled, it transforms into a solid gel known as ‘agar agar’. This medium forms the backbone of Petri dishes and culture slants, which are indispensable for doing culture work and for effective long-term storage.

Available in glass or plastic bottles.
Fills 20 standard 90mm Petri dishes.
Made with premium agar and nutrient supplements.
Premium grade, used in our dedicated laboratory.
Various formulations available (e.g. malt extract, potato dextrose)

Typically non-nutritive on its own, agar is mixed with nutrient-rich bases like malt or yeast extract to serve as a food source for mushroom mycelium. This blend supports healthy fungal growth and is essential to develop vigorous-growing mushroom strains.

Mastery of agar usage allows for the creation of sterile cultures, detailed examination of mycelial development, and the production of clean mushroom spawn. Spores or mycelium fragments placed on the agar surface will germinate and spread, forming a visible network ready for analysis.

Our shipping couriers may leave parcels with a neighbor or in a safe place if no one is home to receive them. To prevent this, please select the designated signed-for service at checkout and ensure you are available to receive the parcel.
