Umbuzo wokuqala: Kudingeka isikhathi esingakanani ukugeza amabhodlela ngosuku olulodwa locwaningo lwesayensi?

Umngane 1: Ngenze i-organic liquid phase synthesis esezingeni eliphezulu cishe unyaka nesigamu, futhi kuthatha cishe ihora elilodwa ukugeza amabhodlela nsuku zonke, okuhlanganisa u-5-10% wesikhathi socwaningo lwesayensi. Ngingabhekwa futhi njengesisebenzi esinekhono lokugeza amabhodlela.
Ngokuphathelene nokuwasha amabhodlela, ngixoxe ngqo nabanye abantu, ikakhulukazi amabhodlela anezintamo ezine kunzima ukuwahlanza, amabhodlela e-buffer kulula ukuwahlanza.

Umngane 2:
Kudingeka kugezwe ithangi elilodwa lesampula elingu-5ml (ama-beakers), kodwa kumele ligezwe ngamanzi angenawo i-ion - 25% nitric acid - 50% hydrochloric acid-deionized water ngaphansi kuka-130℃. Ukugeza ngakunye kuthatha izinsuku ezi-5, ngokwesilinganiso nsuku zonke Hlanza ama-pcs angu-200-500.

Umngane 3:
Izimbiza ezimbili ezinkulu zezitsha ze-petri, amaflaski angunxantathu, kanye nezinye izinhlobo zezitsha zengilazi, ungageza cishe ama-70-100 ngosuku. Ngokuvamile, imishini yamanzi elabhorethri ehlanzekile kakhulu isetshenziselwa ukukhiqiza amanzi nokuhlanza, ngakho-ke umthamo wokuhlanza awukhulu kakhulu.

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

Nazi izingcaphuno ezivela kule mpendulo yabangane abane kuphela, zonke ezibonisa amaphuzu ajwayelekile alandelayo: 1. Ukuhlanza ngesandla 2. Inani elikhulu 3. Kuthatha isikhathi, ubhekene nenani elikhulu kangaka lokuhlanza amabhodlela nezitsha okuthatha isikhathi, wonke umuntu uzizwa kanjani?

Umbuzo 2: Uzizwa kanjani ngokugeza amabhodlela nezitsha isikhathi eside?

Umngane A:

Ngihlale elabhorethri kusukela ekuseni kuze kube sebusuku usuku lonke. Kungabalwa ngempela njengo-007, ngigeza amabhodlela namabhodlela, amabhodlela angenakugezwa.
Abanye abafundi abasanda kuqala elabhorethri bathi inqobo nje uma ithubhu lokuhlola lebhodlela elithinteke ngesandla kumele ligezwe… Impuphu yokuwasha ihlanzwa nge-ultrasound amahora amabili, amanzi ompompi amahora amabili, kanye namanzi ahlanzekile amahora amabili. Uma ithubhu lokuhlola selihlanziwe, amathubhu amathathu okuhlola azophulwa nge-ultrasound. Ingxenye eyodwa (kukhona ibhodlela likadoti eduze kwalo lengilazi ephukile, elagcwaliswa ngesonto)…Ngake ngabuka umfundi osanda kuqala ehlanza amabhodlela angaphezu kwama-50 kusukela ekuseni kuze kube kusihlwa.

Umngane B:
Nginomuzwa wokuthi ukugeza amabhodlela kungathuthukisa ngempela ukubekezela kwabantu, kodwa lezo zivivinyo zidlula nje ezinhlwini futhi kuthatha isikhathi esiningi, futhi kuthatha isikhathi ukugeza amabhodlela, futhi ukungcola nakho kuthinta isivivinyo. Uma uzisebenzisa zonke ngesikhathi esisodwa, nginomuzwa wokuthi ungonga isikhathi esiningi ngempela sokwenza ezinye izinyathelo, futhi kungabhekwa njengokwanda okuncane kwesivinini kanye nokusebenza kahle kwesivivinyo sonke.

Ngemva kokuzwa izimpendulo ezifanele ezivela kulaba bangane ababili, ngangisazizwa ngicasukile ngokugeza inqwaba yamabhodlela engilazi. Ingabe nawe uzizwa ngendlela efanayo? Ngakho kungani ungakhethi ukusebenzisa umshini wokuwasha amabhodlela ozenzakalelayo ngokuphelele?

Umbuzo wesithathu: Ucabangani ngokuhlanza ngesandla uma kuqhathaniswa nomshini wokuwasha amabhodlela?

Umngane 1:
Mina ngokwami, yonke ilabhorethri eyenza i-wet chemistry kufanele ifakwe umshini wokuwasha amabhodlela, njengoba nje yonke imizi kufanele ifakwe umshini wokuwasha kanye nomshini wokuwasha izitsha. Kubalulekile ukonga isikhathi sabafundi nokwenza izinto ezibaluleke kakhulu, okuhlanganisa kodwa kungagcini lapho, ukufunda izincwadi, ukuhlaziya idatha, ukucabanga, ukutshala imali nokuphatha imali, ukuthandana, ukuphuma uyodlala, ukuqeqeshwa emsebenzini, njll.
Ngizwe ukuthi izivivinyo eziningi ze-high-throughput ku-biology zingenziwa ngokuzenzakalelayo ngemishini, kodwa amanye amaqembu ocwaningo asizakala ngezindleko eziphansi zabafundi abaphothule izifundo zabo futhi avumele abafundi abaphothule izifundo zabo basebenze ngezandla. Ukuziphatha okunjalo kuyamangaza.
Ngamafuphi, ngikhuthaza ukuthi yonke imisebenzi ephindaphindwayo engenziwa yimishini ocwaningweni lwesayensi kufanele yenziwe yimishini, futhi abafundi kufanele bavunyelwe ukwenza ucwaningo lwesayensi esikhundleni sokuba yizisebenzi ezishibhile.

Umngane 2:
Uyini umphumela wokuwasha izitsha ezinesimo esikhethekile njenge-NMR tubes/amabhodlela e-Shrek/amabhodlela amancane emithi/ama-sand core funnels? Ingabe ama-test tubes kufanele afakwe ngalinye ngalinye noma angahlanganiswa bese efakwa (njengoba inqubo evamile ye-alkaline tank)?
(Ungayithengi ikhanda elikhulu bese uliphonsa esibelethweni…

Umngane 3:
Umshini wokuwasha amabhodlela udinga imali yokuwuthenga, abafundi abadingi imali yokuwuthenga [vala ubuso]
Izimpendulo zabangani abathathu zikhethiwe ngenhla. Abanye abantu basekela kakhulu ukushintshwa kwemishini yokuwasha amabhodlela esebenzisa izandla, abanye bayangabaza ikhono lokuhlanza imishini yokuwasha amabhodlela, kanye nalabo abangazi okuningi ngemishini yokuwasha amabhodlela. Kungabonakala kulokhu okungenhla ukuthi wonke umuntu akakayiqondi noma akayibuzi i-bottle washer.

Uma sibuyela emuva embhalweni oyinhloko, nansi indlela esemthethweni yokuphendula umbuzo wesithathu:
Izinzuzo zeumshini wokuwasha ingilazi webhubhoratri:
1. Izinga eliphezulu lokuzenzakalela okugcwele. Kuthatha izinyathelo ezimbili kuphela ukuhlanza iqoqo lamabhodlela nezitsha: Faka amabhodlela nezitsha ngokuchofoza okukodwa ukuze uqale uhlelo lokuhlanza (futhi luqukethe izinhlelo ezijwayelekile ezingu-35 nezinhlelo ezenziwe ngokwezifiso ezihlelwa ngesandla ukuze kuhlangatshezwane nezidingo zamakhasimende amaningi elebhu). Ukuzenzakalela kukhulula izandla zabahloli.
2. Ukusebenza kahle kokuhlanza (umshini wokuwasha izingilazi ozenzakalelayoumsebenzi weqoqo, inqubo yokuhlanza ephindaphindwayo), izinga eliphansi lokuphuka kwamabhodlela (ukulungiswa kokucindezela kokugeleza kwamanzi okuzivumelanisa nezimo, izinga lokushisa langaphakathi, njll.), ukuguquguquka okubanzi (ukwamukela osayizi abahlukahlukene kanye nezimo zamashubhu okuhlola, izitsha zePetri, amaflaski evolumu, amaflaski ayindilinga, amasilinda aqediwe, njll.)
3. Ukuphepha okuphezulu nokuthembeka, ipayipi lokungena lamanzi elivikelekile elingenisiwe elifakwe ngaphambilini elingangenisi ukuqhuma, ukumelana nengcindezi kanye nokushisa, akulula ukulilinganisa, nge-valve yokuqapha elwa nokuvuza, ithuluzi lizovaleka ngokuzenzakalelayo lapho i-valve ye-solenoid yehluleka.
4. Izinga eliphezulu lobuhlakani. Idatha ebalulekile efana nokuqhuba, i-TOC, ukuhlushwa kwe-lotion, njll. ingalethwa ngesikhathi sangempela, okuyinto elula kubasebenzi abafanele ukuqapha nokuqonda inqubekela phambili yokuhlanza nokuxhuma uhlelo ukuze luphrinte futhi lulondolozwe, okunikeza lula ukulandelelwa kamuva.
