Erituvchilar asosan suyuq shaklda bo'lgan moddalar bo'lib, ular erigan moddani eritib, eritma hosil qilishi mumkin. Erituvchilarni dielektrik o'tkazuvchanligiga qarab ikki turga bo'lish mumkin: qutbli erituvchilar (masalan, suv) va qutbsiz erituvchilar (masalan, geksan). Polar erituvchilar yuqori dielektrik o'tkazuvchanlikka ega. Ular N yoki o kabi bir yoki bir nechta elektronegativ atomlarga ega, qutbli erituvchilarda mavjud bo'lgan umumiy funktsional guruhlarga spirtlar, ketonlar, karboksilik kislotalar va amidlar kiradi.
