Tsopano, pali njira zambiri zosiyanasiyana zoyeretsera magalasi mu labotale, kutsuka ndi manja, kutsuka ndi ultrasound, makina ochapira odzipangira okha, ndi makina ochapira magalasi odzipangira okha. Komabe, ukhondo wa kuyeretsa nthawi zonse umatsimikizira kulondola kwa kuyesa kotsatira kapena kupambana kwa kuyesako. Mkonzi akufotokoza mwachidule zinthu zingapo zazikulu zomwe zimakhudza kuyeretsa, ndipo akufotokoza mwachidule mfundo zisanu za CTWMT:

C: Chemistry
Malinga ndi cholinga cha zinthu zotsukira, sankhani zigawo zosiyanasiyana za sopo

T: Kutentha 
Kawirikawiri, kutentha kwakukulu kotsuka kudzakhala ndi zotsatira zabwino kwambiri pakutsuka.

W: Ubwino wa Madzi
Madzi ndiye njira yaikulu yoyeretsera, koma ubwino wa madzi umasiyana malinga ndi malo osiyanasiyana, kotero zotsatira zake sizingatsimikizidwe bwino.

M: Mphamvu ya makina
Zotsalirazo zimachotsedwa pamwamba pa chombocho ndi mphamvu zakunja

T: Nthawi
Zinthu zina zonse zikafanana, nthawi zambiri, kuyeretsa kwa nthawi yayitali, kudzakhala ndi zotsatira zabwino zoyeretsa.

Mfundo ya makina ochapira magalasi okha: kutentha madzi, kuwonjezera sopo wapadera kudzera mu pampu yoyendera m'mapaipi a akatswiri okhala ndi mphamvu yochepa komanso kuthamanga kwambiri kuti asambitse pamwamba pa magalasi amkati. Manja opopera apamwamba ndi otsika amatsuka pamwamba pa magalasi. Ndi nthawi yoyeretsa yasayansi komanso masitepe, kuti akwaniritse cholinga choyeretsa magalasi.
