Izinkinga zokuphepha kokudla zihlobene nempilo yawo wonke umuntu, ngakho-ke bekulokhu kugxilwe kuzo umphakathi ngaso sonke isikhathi.Ikakhulukazi eminyakeni yamuva nje, ngezimo ezicebile zezinto ezibonakalayo zabantu kanye nokuthuthukiswa okuqhubekayo kwamazinga okuphila, isidingo sokuhlolwa kokudla siye saqhubeka sikhula.

Eqinisweni, umsebenzi wokuhlola ukudla kanye nokulandeleka ngokuvamile uhlukaniswa izigaba ezimbili: esokuqala singelezinto zokukhucululwa kwendle, kanti esinye ngesezinto ezisezingeni eliphezulu.

Kodwa-ke, kungakhathaliseki ukuthi yiluphi uhlobo, kuyadingeka ukuqinisekisa ukunemba kwemiphumela yokuhlolwa, ngaphandle kwalokho ngeke kwenzeke ukuthuthukisa ukuhlaziywa nokuboniswa okwengeziwe.Ngaphezu kwalokho, ngaphandle kwamasampula okufanele ahlolwe, uma kunenkinga ngamanzi, ama-reagents, noma i-glassware ngesikhathi sokuhlolwa kokudla elabhorethri, khona-ke ubuqiniso bemiphumela yokuhlolwa kokudla buzobuzwa.

Izinyathelo eziyisisekelo zokuhlola ukuphepha kokudla

Ukuhlola ukuphepha kokudla ukusetshenziswa kwemibono eyisisekelo kanye nezindlela zobuchwepheshe ezihlanganisa i-physics, chemistry, biology kanye neminye imikhakha ukuhlola, ukunquma nokuhlaziya izithako eziyinhloko, isimo, kanye nesimo se-microbiological sempahla eluhlaza, izinto ezisizayo, imikhiqizo eqedwe kancane, imikhiqizo eqediwe. , kanye nemikhiqizo.Izinyathelo eziyisisekelo zifaka:

① Qoqa amasampuli: qinisekisa inhloso yokuhlolwa, yenza isikophu sokuhlola nezinto ezithile zamasampula.

② Ukulungiswa kwamasampula: Faka amasampula amasampula emabhodleleni esampula ahlanzekile, bese umaka amabhodlela esampula ngokwezinombolo ze-serial kumasampuli.Amamaki enziwe kufanele akwazi ukuhlonza isimo sokuhlolwa kwesampula.Lungiselela ukucutshungulwa kwangaphambili kwesampula ukuze ulungiselele ijika lesampula nesixazululo sokuthola isampula.

③Amasampuli okuhlola: Ngosizo lwamathuluzi ahlobene, ama-reagents noma izixazululo ezijwayelekile nesixazululo sokuhlola kuzohlolwa ngesikhathi esifanayo.Ngemva kokubala imiphumela yokuhlolwa nokuthola amarekhodi okuqala, umbiko wokuhlola ungabhalwa.

Kule nqubo, amanzi, ama-reagents, ne-glassware kudlala indima ehlukene.

Amanzi: Amanzi ahlanzekile alungiselelwe ngokukhethekile kanye namanzi acwecwe ayisici esibalulekile ohlelweni lokuhlola ukudla.Ezintweni zokuhlola ezijwayelekile, ezifana nokulungiswa kwe-reagent kanye nesigaba senqubo yokuhlola, sebenzisa amanzi agayiwe ajwayelekile njengenketho eyinhloko.Kuyaqapheleka ukuthi lapho kwenziwa ukuzimisela okuthile kokulandela umkhondo, ukuzwela kwamanzi acwengekile kudinga ukucutshungulwa futhi ngaphambi kokuthi kungene esinyathelweni esilandelayo sokuhlolwa kokudla.

Ama-reagents: Ama-reagents ekuhlolweni kufanele asetshenziswe ngokunengqondo ukuze athinte isayensi kanye nokunemba kwemiphumela yokuhlolwa kokudla.Ukunakwa okukhethekile kufanele kukhokhwe empilweni yeshalofu yama-reagents amakhemikhali.Ukugxila kanye nekhwalithi kudinga ukulinganiswa njalo, futhi ukusetshenziswa kwama-reagents amakhemikhali aphelelwe yisikhathi akuvunyelwe, ngaphandle kwalokho kuzothinta ukunemba komphumela wokuthola.Ukwengeza, ukufaka i-titrating isixazululo ngokuhambisana ngokuqinile nezicaciso ezifanele kunganciphisa kakhulu ingozi yokwehluleka kwe-reagent.

I-Glassware: Njengamanje, amabhodlela engilazi noma imikhiqizo ye-polyethylene isetshenziswa kakhulu ekuhloleni ukudla iziqukathi zokuhlola, ezingasetshenziswa ukugcina izidakamizwa, ukuthutha izidakamizwa, kanye nezidakamizwa zokuhlola.Okufana namashubhu okuhlola, amabhekha, amaflaski evolumu, amaflask anesisindo namaflaski e-Erlenmeyer.Kodwa okubaluleke kakhulu ukuqinisekisa ukuthi ukuhlanzeka nokuvuza kwalezi zitsha zengilazi kuhambisana nezindinganiso ezifanele kanye nemininingwane.Ngakho-ke, isitsha somkhiqizo wokuhlola kufanele sigezwe kahle futhi sihlanzwe ngaphambi kokusetshenziswa ukuze kuqinisekiswe ukuthi akukho kungcola okusele.Indima ye-glassware cishe cishe kuzo zonke izici ezibalulekile zokuhlola ukudla.

Yikuphi ukungcola okuyinsalela okuvame ukwenzeka ekuhlolweni kokudla?Ingabe ingahlanzwa?

Noma iyiphi iphrojekthi yokuhlola ukudla izokhiqiza ukungcola okuyinsalela ku-glassware, okufana nezitshalo ezincane, izinsalela zezibulala-zinambuzane, i-formaldehyde, izinsimbi ezisindayo, ama-protease, izithasiselo zokudla, iziqinisi zokudla okunomsoco, izinsalela ze-reagent ekuhlolweni kokuhlola , Ukugeza isivusi ngesikhathi sokuhlanza, njll. Ngakho-ke, i-glassware kufanele ihlanzwe ngaphambi kokusetshenziswa okulandelayo.Kodwa le nqubo ayigcini nje ekuhlanzeni ngezandla.Uma kubhekwa inani elikhulu, ukuhlukahluka, ukushoda kwabasebenzi, kanye nesikhathi esiqinile, ake sibheke izinzuzo zeumshini wokuwasha labkukhiqizwa i-Hangzhou Xipingzhe Instruments Technology Co., Ltd?Isibonelo, umphumela wokuhlanza awugcini nje ngokuthembekile futhi unembile kunokuhlanza ngesandla, kodwa futhi uyarekhoda, uqiniseke, futhi uphindaphindeka!Kuhlanganiswe nezihlakaniphileothomathikhi glassware washerukuze ulawule inqubo yokuhlanza, kulungele kangcono ukwenziwa ngcono sekukonke kokusebenza kahle kwawo wonke ucwaningo lokuhlola ukudla kanye nesiqiniseko sokuphepha.

Ngamafuphi, ukuthuthukisa ukunemba kwemiphumela yokuhlolwa kokudla isiqondiso imboni yokuhlola ukudla eqhubeka nokuyithola.Ukwenza imiphumela yokuhlolwa kokuphepha kokudla ihambisane nedatha yokuhlola yangempela, noma imaphi amanzi, ama-reagents, ne-glassware abalulekile.Ikakhulukazi, ukuhlanzwa kweiwasha glasswareingathuthukisa ngokuqhubekayo ukuhlanzeka ukuze ihlangabezane namazinga alindelekile okuhlolwa kokuhlolwa kokudla.Kungale ndlela kuphela ingasetshenziswa ngempumelelo njengesisekelo senkomba esinenhloso nesilungile.Ngethemba ukuthi abahloli bokudla bazokugcina lokhu engqondweni, futhi bangavumeli umsebenzi wokuhlola ukuphepha kokudla wehlele noma wonakaliswe ngenxa yokuhlanza i-glassware.
