Isikhwama samasampula yisikhwama esivalekile, esisetshenziselwa ukucubungula isampula, ukucebisa kusengaphambili noma ukuhlanjululwa kwesampula lapho kutholwa izinhlobo ezihlukene zamabhaktheriya ekudleni.
▶ Ukwakhiwa Kwesikhwama Sesampula
1. Isikhwama esivaliwe: sidinga ukuguquguquka, ukumelana nomthelela, nokumelana nokubhoboza okuqinile, futhi kufanelekile ukusetshenziswa kuma-homogenizers.
2. Isikrini sokuhlunga: Kudingeka ukuthi ama-bacterial colonies akwazi ukudlula esikrinini sokuhlunga ngokukhululeka, futhi usayizi wegebe lapho insalela yesampula ivinjiwe iyona engcono kakhulu.
3. Uketshezi: ngokuvamile 225mL, kuye ngokuthi ukunothisa noma dilution kudingwa izinhlobo ezahlukene.
▶ Ukusetshenziswa kwezikhwama zesampula
Isetshenziselwa ukucubungula isampula, ukunothisa kwangaphambili noma ukuhlanjululwa kwesampula lapho kutholwa izinhlobo ezihlukene zamabhaktheriya ekudleni.
▶ Ukuhlelwa kwezikhwama zamasampula
Ngokusho koketshezi oluhlukene, ihlukaniswe yaba: I-Buffered Peptone Water Sampling Bag, i-Phosphate Buffered Saline Solution Sampling Bag, I-Normal Saline Sampling Bag, i-GN Enrichment Liquid Sampling Bag, i-Shiga Zeng Bacterial Liquid Sampling Bag, 10% Sodium Chloride Sampling Sampling Bag ye-Tryptone Enrichment , 3% Sodium Chloride Alkaline Protein Jelly Water Sampling Bag, 0.1% Peptone Water Sampling Bag, Sterile Distilled Water Sampling bag, Improved Phosphate Buffer Sampling Bag, Nutritional Meat Soup Sampling Bags, njll.
Ngokwezihlungi ezihlukene, zingahlukaniswa zibe: isikhwama sesampula sokuhlunga esigcwele kanye nesikhwama sokusampula sesihlungi.
▶ Izexwayiso
1. Akuvunyelwe ukuhlolwa komtholampilo.
2. Ifanele kuphela abahloli abaqeqeshiwe.
3. Uma isetshenziswa, izinyathelo zokuzivikela kufanele zithathwe ngamagilavu kanye ne-mask.
4. I-Medium elahliwe kufanele ilahlwe nge-autoclaving.
5. Akuvunyelwe ukusebenzisa umkhiqizo lapho uphelelwe yisikhathi noma ungcolile futhi ungcolile.
