Umbuzo wokuqala: Singakanani isikhathi esidingekayo ukugeza amabhodlela ngosuku olulodwa locwaningo lwesayensi?

Umngane 1: Ngenze i-high-temperature organic liquid phase synthesis cishe unyaka owodwa nesigamu, futhi kuthatha cishe ihora elingu-1 ukugeza amabhodlela nsuku zonke, okubalelwa ku-5-10% wesikhathi socwaningo lwesayensi.Nami ngingathathwa njengesisebenzi esinekhono lokugeza amabhodlela.
Mayelana nokugeza amabhodlela, ngixoxile ngokukhethekile nabanye abantu, ikakhulukazi amabhodlela anentamo emine kunzima ukuwahlanza, amabhodlela e-buffer kulula ukuwahlanza.

Umngane 2:
Kufanele kugezwe ithangi elilodwa kuphela elingu-5ml (amabhika), kodwa kufanele ligezwe ngamanzi angcolile-25% nitric acid-50% amanzi ane-hydrochloric acid-deionized ngaphansi kuka-130 ℃.Ukugeza ngakunye kuthatha izinsuku ezi-5, ngokwesilinganiso nsuku zonke Geza ama-pcs angu-200-500.

Umngane 3:
Izimbiza ezimbili ezinkulu zezitsha ze-petri, ama-flask angama-triangular, nezinye izinhlobo ze-glassware, ungawasha cishe ama-70-100 ngosuku.Ngokuvamile, imishini yamanzi ye-ultrapure yaselabhorethri isetshenziselwa ukukhiqiza nokuhlanza amanzi, ngakho-ke umthamo wokuhlanza awumkhulu kakhulu.

Umngane 4:
Muva nje, bengilokhu ngenza imisebenzi ehlukene elabhorethri.Ngenxa yokuthi i-organic synthesis futhi izidingo ziqinile, ngisebenzisa izingilazi eziningi.Ngokuvamile, kuthatha okungenani ihora ukugeza, okuzwakala kuyisicefe kakhulu.

Nazi izingcaphuno kuphela ezivela kulaba bangane abangu-4, bonke babonisa amaphuzu afanayo alandelayo: 1. Ukuhlanza mathupha 2. Inani elikhulu 3. Kudla isikhathi, ngakho ubhekene nenani elikhulu kangaka lokuhlanza ibhodlela nezitsha ezidla isikhathi, wonke umuntu. has Uzizwa kanjani?

Umbuzo 2: Uzizwa kanjani ngokuwasha amabhodlela nezitsha isikhathi eside?

Umngane A:

Ngahlala elabhorethri kusukela ekuseni kwaze kwaba sebusuku usuku lonke.Ingabala ngempela ukuthi 007, amabhodlela okuwasha namabhodlela, amabhodlela angakwazi ukuwashwa.
Abasanda kuhlanganyela abambalwa elabhorethri ukuthi inqobo nje uma ishubhu lokuhlola lebhodlela elithintwe ngesandla kufanele liwashwe… Impushana yokugeza nge-ultrasonically amahora amabili, amanzi ompompi amahora amabili, namanzi ahlanzekile amanye amahora amabili.Uma ishubhu lokuhlola seligeziwe, amashubhu okuhlola amathathu azophulwa nge-ultrasound.Ingxenye eyodwa (kukhona umgqomo kadoti eduze kwawo wengilazi ephukile, eyagcwaliswa ngesonto)…Ngake ngabona umuntu osanda kuzalwa egeza amabhodlela angaphezu kuka-50 kusukela ekuseni kuze kube kusihlwa.

Umngane B:
Nginomuzwa wokuthi ukugeza amabhodlela kungacijisa ngempela isineke sabantu, kodwa lokho kuhlola kuvele kudlule amakholomu futhi kuthatha isikhathi esiningi, futhi kuthatha isikhathi ukugeza amabhodlela, futhi ukungcola nakho kuthinta ukuhlolwa.Uma uzisebenzisa zonke ngesikhathi esisodwa, nginomuzwa wokuthi ungakwazi ngempela ukonga isikhathi esiningi sokwenza ezinye izinyathelo, futhi kungabhekwa njengokwenyuka okuncane kwejubane nokusebenza kahle kwalo lonke ucwaningo.

Ngemva kokuzwa izimpendulo ezinobulungiswa kulaba bangane ababili, ngangisacasukile ngokuwasha inqwaba yamabhodlela engilazi.Ingabe nawe uzizwa ngendlela efanayo?Ngakho kungani ungakhethi ukusebenzisa iwasha yamabhodlela ezenzakalelayo?

Umbuzo wesithathu: Ucabangani ngokuhlanza ngesandla ngokumelene nomshini wokuwasha amabhodlela?

Umngane 1:
Ngokwami, yonke i-laboratory eyenza i-chemistry emanzi kufanele ifakwe iwasha yamabhodlela, njengawo wonke amakhaya kufanele afakwe umshini wokuwasha kanye nomshini wokuwasha izitsha.Kuyadingeka ukonga isikhathi sabafundi nokwenza izinto ezinengqondo kakhulu, okuhlanganisa kodwa kungagcini lapho, ukufunda izincwadi, ukuhlaziya idatha, ukucabanga, ukutshala nokuphatha imali, ukuthandana, ukuyodlala, ama-internship, njll.
Ngizwile ukuthi izivivinyo eziningi zokuphumelela okuphezulu kubhayoloji zingenziwa ngokuzenzekelayo ngemishini, kodwa amanye amaqembu ocwaningo asebenzisa ngokunenzuzo izindleko eziphansi zabafundi abaneziqu futhi avumele abafundi abathweswe iziqu bazisebenze mathupha.Ukuziphatha okunjalo kuyaxaka.
Ngamafuphi, ngincoma ukuthi yonke imisebenzi ephindaphindwayo engenziwa ngemishini ocwaningweni lwesayensi kufanele yenziwe ngemishini, futhi abafundi bavunyelwe ukwenza ucwaningo lwesayensi esikhundleni sokuba yizisebenzi ezishibhile.

Umngane 2:
Uyini umphumela wokugeza iziqukathi ezimise okukhethekile njengamashubhu e-NMR/amabhodlela e-Shrek/amabhodlela emithi emincane/amafaneli angaphakathi kwesihlabathi?Ingabe amashubhu okuhlola kufanele afakwe ngalinye ngalinye noma angahlanganiswa futhi afakwe (okufana nenqubo evamile yethangi le-alkaline)?
(Ungalithengi ikhanda elikhulu ulijikijele emsebenzini...

Umngane 3:
Iwasha amabhodlela idinga imali yokuthenga, abafundi abayidingi imali yokuyithenga [cover face]
Izimpendulo zabangane abathathu zikhethiwe ngenhla.Abanye abantu bakhuthaza kakhulu ukushintshwa kwemishini yokuwasha amabhodlela, abanye banokungabaza ngekhono lokuhlanza lemishini yokuwasha amabhodlela, kanye nalabo abangenalwazi olutheni ngemishini yokuwasha amabhodlela.Kungabonakala kulokhu okungenhla ukuthi wonke umuntu akazange aqonde noma abuze i-washer yebhodlela.

Uma sibuyela emuva embhalweni omkhulu, nansi imodeli esemthethweni yokuphendula umbuzo wesithathu:
Izinzuzo zeilabhorethri glassware washer:
1. Izinga eliphakeme lokuzenzakalela okugcwele.Kuthatha izinyathelo ezimbili kuphela ukuhlanza iqoqo lamabhodlela nezitsha: Beka amabhodlela nezitsha ngokuchofoza okukodwa ukuze uqale uhlelo lokuhlanza (futhi luqukethe izinhlelo ezijwayelekile ezingama-35 nezinhlelo zokwenza ngokwezifiso ezihlelekayo ukuze kuhlangatshezwane nezidingo zamakhasimende amaningi aselabhorethri).Ukuzenzakalela kukhulula izandla zabahloli.
2. Ukuhlanza okuphezulu (othomathikhi glassware washerumsebenzi we-batch, inqubo yokuhlanza okuphindaphindiwe), izinga eliphansi lokuphulwa kwebhodlela (ukulungiswa okuguquguqukayo kokucindezela kokugeleza kwamanzi, izinga lokushisa langaphakathi, njll.), ukuguquguquka okubanzi (okuhlanganisa amashubhu okuhlola ahlukahlukene, izitsha zePetri, amaflask evolumu, ama-conical flasks, amasilinda athweswe iziqu, njll.)
3. Ukuphepha okuphezulu nokuthembeka, ipayipi yokungena kwamanzi okuphepha okuqhuma ngaphambili efakwe ngaphandle, ukucindezela nokushisa ukumelana, akulula ukukala, nge-valve yokuqapha ephikisana nokuvuza, insimbi izovala ngokuzenzakalelayo lapho i-valve ye-solenoid ihluleka.
4. Izinga eliphezulu lobuhlakani.Idatha ebalulekile efana ne-conductivity, i-TOC, i-lotion concentration, njll. ingase yethulwe ngesikhathi sangempela, esilungele izisebenzi ezifanele ukuqapha nokuphatha kahle inqubekelaphambili yokuhlanza nokuxhuma isistimu ukuze iphrinte futhi ilondoloze, okunikeza lula ukulandeleka kwesikhathi esizayo.
