Biochemical reagents ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb txog lub neej thiab kev tshuaj ntsuam xyuas. Kev ruaj ntseg ntawm lawv cov kev ua tau zoo thiab kev ntseeg siab ntawm cov txiaj ntsig tau zoo nyob ntawm cov qauv kev ua haujlwm thiab kev tswj hwm. Kev cia khoom tsis raug, kev npaj, lossis kev siv yuav ua rau txo qis kev ua haujlwm, cuam tshuam tom qab, lossis txawm tias kev sim tsis ua haujlwm. Yog li ntawd, cov kev ceev faj yuav tsum tau ua raws li nruj me ntsis thoob plaws hauv kev siv biochemical reagents los xyuas kom meej qhov tseeb ntawm cov ntaub ntawv sim thiab cov neeg ua haujlwm nyab xeeb.
Ua ntej, thaum lub sij hawm txais thiab txais cov txheej txheem, lub npe, batch naj npawb, specifications, hnub tas sij hawm, thiab cov tsos ntawm cov reagents yuav tsum tau xyuas. Yog hais tias cov kua reagents qhia turbidity, nag lossis daus, los yog xim txawv txav, los yog yog cov hmoov pom clumping los yog deliquescence, lawv yuav tsum tau muab tshem tawm thiab lawv usability soj ntsuam. Tag nrho cov reagents yuav tsum tau muab cia rau hauv ib qho chaw tsim nyog; feem ntau xav tau kev tiv thaiv los ntawm lub teeb, tsis kub, los yog khov. Cov xwm txheej tshwj xeeb yuav tsum raug xa mus rau cov lus qhia lossis daim ntawv lo kom tsis txhob degradation los yog denaturation tshwm sim los ntawm qhov kub thiab txias hloov los yog lub teeb raug. Rau cov tshuaj reagents uas raug rau cov kab mob microbial, cov mob aseptic yuav tsum tau ua raws, thiab aseptic xwm txheej yuav tsum tau kuaj xyuas tsis tu ncua.
Thaum lub sij hawm npaj thiab siv, siab - cov kuab tshuaj purity thiab ntim yuav tsum nyiam kom tsis txhob muaj kev sib cuam tshuam ntawm cov impurities thiab lub hom phiaj tsom xam. Kev ntsuas qhov hnyav thiab cov raj xa dej yuav tsum tau ua los ntawm kev siv cov cuab yeej ntsuas ntsuas thiab cov khoom siv, ua raws li lub hauv paus ntsiab lus ntawm qhov yuam kev yam tsawg kawg nkaus kom ntseeg tau qhov tseeb ntawm cov concentration thiab ntim. Thaum soj ntsuam nrog bioactive reagents xws li enzymes los yog cov tshuaj tiv thaiv kab mob, lub sij hawm raug rau ntawm chav tsev kub yuav tsum txo kom tsawg; kev khiav hauj lwm yuav tsum tau ua zoo dua nyob rau hauv ib da dej dej khov los yog qis - ib puag ncig kub los tiv thaiv kev ua haujlwm attenuation. Npaj cov kev daws teeb meem yuav tsum tau siv nyob rau hauv lub sij hawm teev; ib qho seem seem yuav tsum tau muab khaws cia kom zoo lossis muab pov tseg raws li qhov yuav tsum tau muaj kev ruaj ntseg.
Cov reagents sib txawv tuaj yeem cuam tshuam; Cov tshuaj tsis sib xws yuav tsum zam kom tsis txhob sib xyaw. Piv txwv li, muaj zog oxidants thiab txo cov neeg ua haujlwm tuaj yeem ua ke, ua rau tsis muaj zog; high concentrations ntawm ntsev los yog cov kuab tshuaj organic yuav hloov lub zog ionic ntawm lub buffer system, yog li cuam tshuam cov tshuaj tiv thaiv tshwj xeeb. Rau kev tshawb nrhiav multiplex lossis kev siv ua ke, ib qho me me - ntsuas qhov sib piv yuav tsum tau ua ua ntej kom paub meej tias qhov tsis muaj kev cuam tshuam ua ntej scaling.
Kev ceev faj txog kev nyab xeeb yog qhov tseem ceeb. Qee cov tshuaj biochemical reagents yog tshuaj lom, corrosive, sensitizing, los yog flammable thiab tawg. Cov cuab yeej tiv thaiv tus kheej tsim nyog, xws li cov tsho hauv chav kuaj, hnab looj tes, tsom iav, thiab lub qhov ncauj qhov ntswg, yuav tsum hnav thaum tuav, thiab kev ua haujlwm yuav tsum tau ua nyob rau hauv qhov chaw zoo - qhov cua. Cov kauj ruam uas muaj qhov tsis zoo lossis aerosol- tsim cov tshuaj yuav tsum ua kom zoo rau hauv lub txee biosafety lossis fume hood kom txo tau qhov kev pheej hmoo ntawm kev nqus pa. Laboratory pov tseg yuav tsum tau muab sau thiab pov tseg raws li cov kev cai rau cov tshuaj phem los yog biohazardous cov ntaub ntawv los tiv thaiv ib puag ncig muaj kuab paug thiab cov neeg raug mob.
Cov ntaub ntawv khaws cia thiab traceability yog qhov tseem ceeb rau kev ua kom zoo ntawm kev siv reagent. Cov ntaub ntawv ntxaws ntxaws yuav tsum tau khaws cia ntawm cov reagent qhov chaw, hnub npaj, batch naj npawb, cia tej yam kev mob, thiab kev sim phenomena pom los pab txhawb traceability tsom xam nyob rau hauv cov ntaub ntawv ntawm anomalies. Kev txheeb xyuas cov khoom lag luam tsis tu ncua thiab ua ntej siv cov khoom lag luam ze rau hnub tas sij hawm tuaj yeem txo qis kev ua haujlwm tsis zoo thiab kev lag luam poob vim yog tas sijhawm.
Hauv cov ntsiab lus, kev siv tus qauv biochemical reagents yog qhov tseem ceeb thoob plaws hauv tag nrho cov txheej txheem ntawm kev txais, khaws cia, npaj, tuav, thiab pov tseg. Tsuas yog los ntawm kev ua raws li kev ceev faj nruj heev tuaj yeem ua rau lawv qhov kev ua tau zoo ruaj khov, ua kom muaj kev tsim tawm thiab kev tshawb fawb nruj ntawm cov txiaj ntsig kev sim, thaum tseem muab cov khoom lav rau kev tswj xyuas kev nyab xeeb.
