1. Qalabka ma awoodo inuu soo qaado dareeraha xilliga ugu sareeya heerkulka ka sareeya 30 ℃, gaar ahaan waxyaabaha karkaraya, sida qabka ugu yar ee dichloromethane ama ether.
Fadlan hubi in heerkulka himilooyinka uu ka hooseeyo 30 ℃.
2. Hawada hawada ku mashquulsan tuubbada inta ay dhibaatadu ka baxdo hawlgallada muddo dheer.
Fadlan ku dar ethanol usha odaadka madaxa bamka (falanqaynta saafiga ah ama ka sareeya) oo kor u qaad heerka qulqulka waqti isku mid ah. Xiriiriyaha hortiisa bamka hortiisa burburay ama dabacsan, tani waxay u horseedi doontaa safka inuu hawada hawada ka hubiyo in iskuxirka tuubbada uu dabacsan yahay.
3. Xiriiriyaha hortiisa bamka hortiisa ayaa dhaawacmay ama dabacsan, waxay u horseedi doontaa safka inuu hawada ka daadiyo.
