Osnovno obja\u0161njenje metode pranja drhtanjem vode.<\/em><\/p>\n\n\n\n Ako na unutra\u0161njoj stijenci postoje tvari koje se ne mogu lako ukloniti, upotrijebite \u010detku za \u010di\u0161\u0107enje.

Ako je potrebno, koristite destilovanu vodu i isperite ga tri puta. U \u010distom stanju voda \u0107e se ravnomjerno razlijevati bez stvaranja kapljica (kao \u0161to je prikazano na lijevoj slici), dok \u0107e se u ne\u010distom stanju kapljice vode zadr\u017eati na povr\u0161ini (kao \u0161to je prikazano na desnoj slici).<\/p>\n\n\n\n Ako staklena posuda sadr\u017ei vodotopive tvari poput lu\u017eina, karbonata ili baznih oksida, prvo dodajte klorovodi\u010dnu kiselinu da ih rastopite, a zatim isperite vodom. Ako je prisutna mast ili ulje, upotrijebite vru\u0107u otopinu natrijevog karbonata, a zatim isperite \u010detkom. Alternativno, upotrijebite \u010detku s malom koli\u010dinom deterd\u017eenta. Za instrumente uskog vrata koje je te\u0161ko \u010detkati, isperite malom koli\u010dinom aqua regia ili otopinom kromove kiseline. Ako ni ove metode ne uspiju, namo\u010dite predmet u koncentriraniju otopinu, a zatim isperite vodom.<\/p>\n\n\n\n Sigurnosni savjet: Uvijek zbrinite otpadnu teku\u0107inu prije dodavanja vode i izbjegavajte \u010di\u0161\u0107enje vi\u0161e epruveta istovremeno.<\/strong> Obja\u0161njenje metoda prirodnog su\u0161enja na zraku i su\u0161enja u pe\u0107nici.<\/em><\/p>\n\n\n\n Obja\u0161njenje upotrebe komprimiranog zraka i zagrijanog zraka za su\u0161enje.<\/em><\/p>\n\n\n\n Obja\u0161njenje su\u0161enja zasnovanog na protoku zraka i tehnika brzog su\u0161enja.<\/em><\/p>\n\n\n\n Prijedlog za ilustraciju: Razmotrite dodavanje jasnih dijagrama ili fotografija svake metode su\u0161enja kako biste korisnicima pomogli da bolje razumiju razlike i prakti\u010dne primjene.<\/strong><\/p>\n\n\n\n Obja\u0161njenje uputstava za upotrebu cilindara s podjelom i mjernih \u0161oljica za mjerenje te\u010dnosti.<\/em><\/p>\n\n\n\n Mjere opreza pri upotrebi pipeta uklju\u010duju:<\/p>\n\n\n\n Prijedlog za ilustraciju: Prilo\u017eite sliku koja prikazuje ispravne i neispravne metode upotrebe pipete.<\/strong><\/p>\n\n\n\n Koraci operacije uklju\u010duju: \u010di\u0161\u0107enje \u2192 nano\u0161enje vazelina \u2192 provjeru curenja \u2192 punjenje radnim rastvorom \u2192 ispuhivanje burete \u2192 titraciju.<\/p>\n\n\n\n Sigurnosni savjet: Prilikom upotrebe vazelina za zaptivanje, osigurajte da otopina nije kontaminirana, jer bi to moglo utjecati na ta\u010dnost titracije.<\/strong><\/p>\n\n\n\n Prije upotrebe volumetrijske boce provjerite curi li \u010dep. Kvalificirani \u010dep treba biti pri\u010dvr\u0161\u0107en oko vrata boce i ne smije se proizvoljno mijenjati. Ako kapljice vode ostanu iznad kalibracijske oznake na unutra\u0161njoj stijenci, to mo\u017ee utjecati na to\u010dnost, pa se bo\u010deta mora temeljito o\u010distiti. Sve \u010dvrste tvari koje se trebaju izva\u017eati prvo se otapaju u maloj mjernoj posudi, a zatim, nakon hla\u0111enja na sobnu temperaturu, prenose u volumetrijsku bo\u010detu. Bo\u010deta se nikada ne smije zagrijavati niti su\u0161iti u pe\u0107nici.<\/p>\n\n\n\n Prijedlog za ilustraciju: Dodajte sliku koja prikazuje ispravnu tehniku mije\u0161anja otopine u volumetrijskoj bo\u010dnici.<\/strong><\/p>\n\n\n\n Dodatni savjet: Osigurajte da se sve volumetrijske operacije izvode na sobnoj temperaturi kako bi se odr\u017eala ta\u010dnost otopine.<\/strong><\/p>","protected":false},"excerpt":{"rendered":" This article provides a detailed explanation of the cleaning, drying, and usage methods for laboratory glassware.
