Iimeko eziyimfuneko zokuvelisa iingcebiso ezikumgangatho ophezulu wePipette
Iingcebiso zePipette zezona zinto zixhaphakileyo zisetyenziswa elabhoratri.Ifuna ukuchaneka komgangatho ophezulu kunye nokugxila okuhle, kwangaxeshanye, udonga lwangaphakathi lufuna umtyibilizi akukho manqaku okuhamba, kwaye incam ayifakwanga burr.
Makhe sichaze amanqaku enkqubo kwinkqubo yokuvelisa:
Ukukhetha indawo yemveliso eyi-1
Iingcebiso kufuneka zisetyenziswe ekubhaqweni kwe-molecular, ukuxilongwa kwe-in vitro, ukuhlolwa kwangaphambili kunye nezinye iimvavanyo, ngoko iingcebiso ze-pipette zifuna kakhulu ngokusingqongileyo kwimveliso, njengobukho bezinto eziphilayo zangaphandle kumphezulu weengcebiso zinokuchaphazela ngokuthe ngqo iziphumo zohlalutyo.Okwangoku, ikhulu lamawaka eeworkshops ezingenathuli lukhetho lwesiqhelo.
Ukukhetha izixhobo ze-2 zokuvelisa
Iimveliso zencam zinemingxuma emininzi, umngxuma onzulu, udonga olucekethekileyo kunye nomjikelo wokubumba okhawulezayo, ekufuneka ube nokusebenza kakuhle kokubumba, izinga eliphantsi lokungaphumeleli kunye nokusebenza okuzinzileyo kwexesha elide malunga nokukhethwa kwezixhobo, ke ngoko, umatshini wokutofa ngombane okhawulezayo ukhetho oluphezulu, oluneempawu ezilandelayo:
*Umatshini wokubumba owenziwe ngesantya esiphezulu sombane uyahlangabezana neemfuno zamanqaku acokisekileyo anodonga olucekethekileyo, ukunciphisa uxinzelelo lokunyuswa kwencam yepipette ethe ngqo eyenziwe yincam yepipette ngexesha lokubumba;
* Isantya semowudi evulekileyo kunye nokuchaneka kuzinzile ngakumbi kwi-manipulator ezenzekelayo yokubamba indawo yemveliso;
*Uzinzo kunye nokuveliswa kwakhona okuphezulu.I-Motor inkqubo yamandla amaninzi ilawulwa yinkqubo yokuma yodwa kwaye isikhunta sivumela isenzo ngaxeshanye.
3 inkqubo yokuqwalaselwa
Eyona nto inganqwenelekiyo yeemveliso zeengcebiso zilahlekileyo yintloko, i-deformation yokugoba, imiphetho yeenwele zentloko kunye nomlomo, ukuzinza komda kunye nezinye iingxaki.Ukuphendula le miba ingentla, la manqaku alandelayo kufuneka aqatshelwe kweyona nkqubo yemveliso:
*Isantya sokukhupha esinengqiqo.
Ukukhawuleza ngokukhawuleza kuya kukhokelela ekuvuzeni komoya kunye neglue kwincam, kwaye igesi ayikwazi ukukhutshwa kakuhle.Ukucotha kakhulu kuya kukhokelela kuxinzelelo olukhulu lwangaphakathi kwimveliso, imveliso igobile, kwaye ukuthe tye akwanele.Kufuneka usebenzise kancinci ukungunda okunyukayo, kunye nemo yemveliso kuqwalaselo olunengqiqo ukukhetha.
*Iyahambelana nemathiriyeli ekrwada
① Izixhobo ezinokuqukuqela ngcono zikhethelwe ukuqinisekiswa kweparamitha ezisezantsi, ezenze ukuzaliswa ngokukhawuleza kwemathiriyeli ekrwada kube lula, ukhetho loxinzelelo olufanelekileyo kunye nokukhuselwa kweemayile ezichanekileyo kunye nokunciphisa ukuba nokwenzeka kwembonakalo embi.
② Ubushushu obufanelekileyo.Izixhobo ezikrwada zePP zezemathiriyeli yekristale ubushushu obuphantsi kakhulu buzakukhokelela kwinkangeleko yezixhobo ezicothayo zeekristale zeemveliso ezinkungu kunye ne-opaque, iimveliso ziba brittle kunye nezinye izinto ezingafunekiyo, ubushushu obuphezulu kakhulu buya kukhokelela ekuthotyweni kwamandla wemathiriyeli ekrwada.
*Ukutshintsha okufanelekileyo kweV / P
Ukuze kuqinisekiswe isitofu esilungeleleneyo, ukugunyaziswa kwemveliso kufuneka kuzalise ngokuthe ngcembe ukusuka kwi-ejection emfutshane, iimveliso ezimfutshane zokukhupha kufuneka ziqwalasele ngononophelo ibhalansi kunye nencam yokuzalisa i-eccentricity.Kwaye ukuyila ingqiqo V / P ukutshintsha.Gwema iimeko ezinjengokusilela kweglue kwincam yepipette, imiphetho yeenwele, ukungabikho kokuthe tye, njl.
*Automation
① Ngesenzo esizenzekelayo sokufunxa, igeyiji yoxinzelelo olubi kufuneka ifakwe ukujonga ixabiso lokutshintsha ubungakanani bevacuum, ngelixa ubeka uluhlu olufanelekileyo lwevacuum kunye nonxibelelwano lwezixhobo, ukufezekisa isenzo esingaqhelekanga xa ukhuseleko lokungunda kunye nokufumanisa okuncedisayo kokuqhekeka kwemveliso. .
② Zoba ubungakanani begesi kwipleyiti yesixhobo ukuze yanele, uthabathe umgca omkhulu kangangoko.
③ Umzimba wombhobho wesibambi ukhetha imathiriyeli yeplastiki + isakhiwo esithintelweyo kangangoko kunokwenzeka.
