Materials
- Nutrient Broth
- Nutrient Plates
- Pasteur pipette
Procedure
Freeze- dried cultures are supplied in vacuum- sealed ampoules.
- Make a small file mark on the ampoule enar the middle of the cotton wool plug.
- Touch the file mark with a red hot glass rod till the glass cracks.
- Wait a few seconds to allow air ot enter into the amploule.
