Tlhaloso ea Sehlahisoa
Libotlolo tsa khalase ke khetho e ntle haholo bakeng sa ho paka lino ka lebaka la hore li ka sebelisoa hape. Li ka qhibilihisoa 'me tsa sebelisoa hape ho etsa lihlahisoa tse ncha tsa botlolo ea khalase, e leng se tlatselletsang potolohong e tsitsitseng ea ho paka. Ka tloaelo, hoo e ka bang 30% ea libotlolo tsa rona tsa libotlolo tsa khalase li entsoe ka likhalase tse nchafalitsoeng tse tsoang litsing tsa rona kapa limmarakeng tsa kantle, e ntse e totobatsa boitlamo ba rona boikarabellong ba tikoloho.
Libotlolo tsa rona tsa likhalase li fumaneha ka mefuta e fapaneng ea li-droppers, ho kenyelletsa le li-droppers tsa bulb, li-push-button droppers, li-droppers tsa ho itlama, le li-droppers tse etselitsoeng ka ho khetheha. Libotlolo tsena li sebetsa e le tharollo ea mantlha ea ho paka bakeng sa lino, haholo oli, ka lebaka la ho lumellana ha tsona le khalase. Ho fapana le li-droppers tsa setso tse ka 'nang tsa se ke tsa fana ka litekanyetso tse nepahetseng, litsamaiso tsa rona tse etselitsoeng ka ho khetheha li netefatsa phano e nepahetseng, li ntlafatsa boiphihlelo ba mosebelisi le ho fokotsa litšila tsa sehlahisoa.
Re fana ka likhetho tse fapaneng tsa libotlolo tsa dropper ka har'a mekhahlelo ea rona ea setoko, e u lumellang hore u khethe sephutheloana se loketseng lihlahisoa tsa hau. Ka meralo e fapaneng ea libotlolo tsa khalase, libopeho tsa tleloubu le mefuta e fapaneng ea pipette, re ka etsa le ho etsa likarolo tsa hau ho fana ka tharollo e ikhethang ea botlolo ea li-dropper ho litlhoko tsa hau tse ikhethang.
Tumellanong le boitlamo ba rona ba ho tšoarella, re ntse re tsoela pele ho ntlafatsa ka likhetho tsa libotlolo tse bobebe tsa khalase le likhetho tse tsitsitseng tse kang li-droppers tse le 'ngoe tsa PP, li-droppers tsa polasetiki tsohle le li-droppers tse fokotsehileng tsa polasetiki. Maiteko ana a bontša boitlamo ba rona ba ho theha lefatše le betere ka ho sebelisa litharollo tsa ho paka tse baballang tikoloho.
