Parafilm Strips for Sealing Petri Dishes

Parafilm strips measuring 25cm x 10cm or 50cm x 10cm

Parafilm is an elastic and breathable material used to seal Petri dishes containing agar. Sealing with Parafilm keeps your agar and cultures protected from contaminants for a long time. 

You can cut it to any size you want.

We always recommend trying to have a double layer around your Petri dishes in case a hole or crack forms that could contaminate your dish.
