X10 pre poured sterile malt extract agar plates. Comes with extra parafilm to reseal plates. Winter advice: please warm plates slowly as a rapid increase in temperature will cause an excessive amount of condensation. The best method we have seen so far is to place the plates in a cooler outside and bring them in.
This will provide a buffer that allows them to warm up at a slower rate. This item is made of malt extract, agar, petri dish and parafilm.
