Sorghum syrup + lab grade yeast extract. Sealed 10 pack of petri dishes - size 100 x 15 cm. The petri dishes come sterile, sealed and ready to work with. It is advised to open these in front of your flow hood or sab/still air box. It is also recommended to store any extra plates in a clean ziploc in between use, as leaving them in the open subjects them to airborne contamination if not sealed properly.
10 strips of parafilm are provided for properly sealing each plate after use. Please inspect the dishes before opening. This item is made of agar agar, sorghum and lab grade yeast extract.
