Mbale ya petri ndi mbale ya labotale yomwe imagwiritsidwa ntchito ngati tizilombo toyambitsa matenda kapena ma cell.Zimapangidwa ndi pansi, ngati disc ndi chivindikiro.Nthawi zambiri amapangidwa ndi galasi kapena pulasitiki.Zida za Petri zimagawidwa m'magulu awiri, makamaka pulasitiki ndi galasi, galasi lingagwiritsidwe ntchito ngati zomera, chikhalidwe cha tizilombo toyambitsa matenda ndi chikhalidwe chotsatira maselo a nyama zingagwiritsidwenso ntchito.Pulasitiki ikhoza kukhala ya polyethylene, yotayika komanso yogwiritsidwa ntchito kangapo, yoyenera kuyika ma laboratory inoculation, kuyika chizindikiro, ntchito zolekanitsa mabakiteriya, zingagwiritsidwe ntchito pa chikhalidwe cha zomera.Kwa zitsanzo zaulere chonde mverani momasuka kuti mutilankhule.
