These ready-to-use, sterile, petri plates (100mm x 15mm) contain a Tryptic Soy Agar with 5% sheep's blood. Ideal for general bacteria growth science projects when handled properly. These ten plates are supplied in a sterile-wrapped package.
Just swipe plate surface with bacteria collected on a sterile swab and let grow in a warm, undisturbed location.
These perishable plates are sensitive to temperature. During extreme hot or cold weather we recommend choosing either Priority Air (2-3 days) or Urgent (1 Day) as your shipping method. Otherwise, Standard Ground should be OK.
Refrigerate immediately when received. These plates will generally keep up to three months when refrigerated. Each pack is stamped with an expiration date.
CAUTION. Most bacteria collected in the environment will not be harmful. However, once they multiply into millions of colonies in a petri dish they become more of a hazard. Be sure to protect open cuts with rubber gloves and never ingest or breathe in growing bacteria. Keep growing petri dishes sealed closed with tape or Parafilm until your experiment is done. Then you should safely destroy the fuzzy bacteria colonies using bleach.
