Ukupakisha kunye noGcino

Izinto eziqinisekisiweyo zereferensi zipakishwe kwiibhotile zeglasi ezineengubo zeplastiki.Ubunzima obushiyekileyo yi-50g nganye.Kucetyiswa ukugcina ukoma xa ugcinwe.Izinto eziqinisekisiweyo zokubhekisela kufuneka zomiswe kwi-105 ℃ ngeyure eyi-1 ngaphambi kokusetyenziswa, emva koko kufuneka zikhutshwe kwaye zipholile kwiqondo lokushisa.
