Cheebtsam thiab Kev Ua Haujlwm

Ib qho rotovap muaj ntau yam tseem ceeb:

01/

Rotating Flask: Tuav cov qauv kev daws teeb meem.

02/

Dej Da Dej: Ua kom sov cov qauv kom yooj yim evaporation.

03/

Condenser: Cools lub vapor rov mus rau hauv cov kua daim ntawv.

04/

Tau txais Flask: Sau cov kuab tshuaj condensed.

05/

Lub tshuab nqus tsev: Txo qhov siab kom txo qhov kub ntawm qhov hnyav.

06/

Lub rotovap ua haujlwm los ntawm kev tig lub raj mis uas muaj cov qauv kev daws teeb meem hauv chav da dej kub hauv qab lub tshuab nqus tsev.

Kev Tiv Thaiv Kev Nyab Xeeb

Ua ntej ntxiv cov tshuaj ntxiv rau lub tshuab rotovap, nws yog ib qho tseem ceeb kom ua raws li cov kev ceev faj txog kev nyab xeeb:

Cov cuab yeej tshuaj xyuas thiab tu: Ua ntej pib, ua tib zoo tshuaj xyuas ntawm rotovap. Tshawb xyuas cov cim qhia ntawm kev hnav lossis kev puas tsuaj, tshwj xeeb tshaj yog nyob rau hauv cov ntsaws ruaj ruaj, pob qij txha, thiab khob iav. Xyuas kom tag nrho cov kev sib txuas yog nruj thiab ruaj ntseg kom tsis txhob muaj cov dej xau thaum ua haujlwm. Kev saib xyuas tsis tu ncua, xws li lubricating qhov txav mus los thiab hloov cov khoom siv tsis tu ncua, yuav tsum tau teem sijhawm kom lub rotovap nyob rau hauv qhov zoo.

Cov cuab yeej tiv thaiv tus kheej:

Ib txwm hnav PPE tsim nyog thaum ua haujlwm nrog rotovap. Qhov no suav nrog cov tsom iav kev nyab xeeb los tiv thaiv kev tawg los yog nchuav, hnab looj tes los tiv thaiv tes los ntawm cov tshuaj, thiab lub tsho tiv no los yog lub kaus mom los npog cov khaub ncaws. PPE txo qis kev pheej hmoo ntawm kev raug cov khoom phom sij thiab txhim kho kev nyab xeeb ntawm tus kheej thaum ua haujlwm.

Kev tswj qhov cua thiab fume:

Xyuas kom lub chaw soj nstuam muaj qhov cua kom zoo ua ntej ua haujlwm rotovap. Qhov no yuav pab cuam tshuam cov vapors lossis fumes generated thaum lub sij hawm evaporation txheej txheem, txo qhov kev pheej hmoo ntawm inhalation. Siv lub fume hood thaum tuav cov kuab tshuaj volatile kom txo tau qhov tshwm sim ntxiv thiab tswj cov huab cua zoo hauv qhov chaw sim.

Cov txheej txheem ua haujlwm thiab raws tu qauv:

Ua raws li cov txheej txheem ua haujlwm tau tsim thaum ntxiv cov tshuaj ntxiv rau rotovap. Pib los ntawm maj mam nchuav cov tshuaj rau hauv lub khob evaporation, kom ntseeg tau tias nws tsis tshaj qhov siab tshaj qhov ntim tau pom zoo rau kev ua haujlwm nyab xeeb. Saib xyuas qhov kev sib hloov ceev thiab qhov kub thiab txias raws li cov kuab tshuaj raws li qhov yuav tsum tau ua kom tsis txhob muaj cua sov los yog hloov siab tam sim ntawd.

Ntxiv cov tshuaj ntxiv rau lub tshuab Rotovap

Npaj Txoj Kev daws

Ntsuas cov tshuaj: Ntsuas qhov tseeb ntawm cov tshuaj uas koj xav tau ntxiv. Siv lub tog raj kheej kawm tiav los yog lub pipette kom paub meej.

Dilute yog tias tsim nyog: Nyob ntawm qhov concentration, koj yuav tsum tau dilute qhov kev daws teeb meem kom tswj tau qhov sib xws hauv cov txheej txheem.

 

Ntxiv qhov kev daws teeb meem

Nres qhov kev sib hloov:

Tua tawm qhov kev sib hloov ntawm lub raj mis kom tsis txhob txaws thiab ua kom ruaj khov.

01

Qhov System:

Qhib lub qhov cua valve kom sib npaug ntawm lub siab ua ntej ntxiv cov tshuaj ntxiv. Cov kauj ruam no yog qhov tseem ceeb los tiv thaiv kev raug mob hnyav.

02

Tshem lub Flask:

Ua tib zoo tshem lub khob rotating los ntawm lub tshuab rotovap.

03

Ntxiv qhov kev daws teeb meem:

Maj mam ncuav cov tshuaj ntxiv rau hauv lub khob. Siv lub funnel kom tsis txhob nchuav thiab ua kom cov tshuaj ntxiv sib npaug.

04

Reattach lub Flask:

Ruaj ntseg rov qab muab lub hwj rau lub rotovap. Xyuas kom txhua qhov kev sib txuas yog nruj thiab tsis muaj qhov xau.

05

Rov pib ua haujlwm

Kaw lub Vent Valve: Tom qab ntxiv cov tshuaj, kaw lub qhov cua kom rov tsim lub tshuab nqus tsev.

Rov pib qhov kev sib hloov: Tig rau qhov kev sib hloov ntawm lub hwj.

Saib xyuas cov txheej txheem: Khaws lub qhov muag ntawm cov txheej txheem evaporation kom ntseeg tau tias nws ua haujlwm zoo. Kho qhov kub thiab lub tshuab nqus tsev yog tias tsim nyog.

Lub tswv yim rau kev ua haujlwm zoo

Rotary evaporators, lossis rotovaps, yog cov cuab yeej tseem ceeb hauv chav kuaj rau cov kuab tshuaj evaporation. Kev ua haujlwm tau zoo thaum ntxiv cov tshuaj ntxiv rau rotovap suav nrog kev ua raws li cov kev coj ua zoo tshaj plaws kom ntseeg tau tias kev ua tau zoo thiab kev nyab xeeb.

1. Kev npaj thiab teeb tsa

Ua ntej pib, xyuas kom lub rotovap huv si thiab tag nrho cov khoom sib dhos kom zoo. Tshawb xyuas cov ntsaws ruaj ruaj, cov pob qij txha, thiab cov iav iav kom muaj kev puas tsuaj lossis cov dej xau uas tuaj yeem cuam tshuam rau kev ua haujlwm. Muab cov cuab yeej tso rau ntawm qhov chaw ruaj khov thiab ua kom muaj cua txaus kom tawg cov vapors.

2. Optimal Solvent Management

Xaiv cov kuab tshuaj uas tsim nyog rau koj daim ntawv thov thiab xyuas kom meej tias nws sib haum nrog rotovap cov ntaub ntawv thiab cov lus qhia tshwj xeeb. Thaum ntxiv cov tshuaj ntxiv, ncuav nws maj mam mus rau hauv lub khob evaporation kom tsis txhob nchuav thiab xyuas kom nws tsis pub dhau qhov kev pom zoo. Qhov no tiv thaiv overloading thiab tswj cov evaporation npaum li cas. Xyuas kom meej tias cov kuab tshuaj siv tau tshiab thiab tsis muaj kab mob. Qhov kev xyaum no pab tswj kev ua haujlwm ntawm cov txheej txheem evaporation.

3. Peb yog cov kws tshaj lij kev lag luam loj tshaj plaws

Teem lub tshuab rotovap rau qhov kub thiab txias thiab kev sib hloov ceev raws li qhov hnyav tus yam ntxwv thiab qhov xav tau evaporation tus nqi. Qhov kub siab dua tuaj yeem ua kom cov evaporation nrawm dua, tab sis tuaj yeem ua rau cov khoom sib xyaw ua ke. Kho qhov kev sib hloov ceev kom ua tiav qhov pom ntawm qhov chaw raug qhov chaw uas tsis ua rau ntau dhau foaming lossis txaws.

4. Kev soj ntsuam thiab kev hloov kho

Tsis tu ncua saib xyuas cov txheej txheem evaporation kom ntseeg tau tias nws ua haujlwm zoo. Kho qhov ntsuas raws li qhov tsim nyog los tswj cov xwm txheej ruaj khov thiab tiv thaiv kev hloov pauv sai ntawm lub siab lossis kub. Siv cov kev ntsuas kev nyab xeeb xws li lub hood fume thiab hnav PPE tsim nyog los tiv thaiv cov vapors thiab nchuav.

5. Kev tu thiab tu

Ntxuav cov khoom rotovap tsis tu ncua los tiv thaiv cov khoom seem. Siv cov tshuaj ntxuav kom tsim nyog raws li kev pom zoo los ntawm cov chaw tsim khoom. Tsis tu ncua xyuas cov ntsaws ruaj ruaj thiab gaskets rau hnav thiab tsim kua muag. Hloov lawv raws li xav tau los tswj lub tshuab nqus tsev.

 

Los ntawm kev ua raws li cov lus qhia no, lub chaw soj nstuam tuaj yeem txhim kho kev ua haujlwm thiab kev nyab xeeb ntawm kev siv rotovap rau hnyav evaporation. Kev npaj kom zoo, kev tswj qhov hnyav, ceev faj qhov kub thiab txias thiab kev hloov pauv, thiab kev saib xyuas ceev faj yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo ib yam thaum ua kom lub neej ntev ntawm cov khoom siv.

Xaus

Ntxiv cov tshuaj ntxiv rau lub tshuab rotovap yog ib txoj hauv kev yooj yim, tab sis nws yuav tsum tau ua tib zoo tuav thiab saib xyuas kom meej. Los ntawm kev ua raws li cov kauj ruam tau teev tseg hauv phau ntawv qhia no thiab ua raws li kev ceev faj txog kev nyab xeeb, koj tuaj yeem ua kom muaj kev ua haujlwm zoo thiab ua haujlwm ntawm koj rotovap.
