Iindidi ezininzi zeengcebiso, ungakhetha njani ingcebiso efanelekileyo kunye nexabiso eliphantsi?

Makhe sihambe kwaye siqwalasele ezi ngongoma zingezantsi, eziye zasombulula, sikholelwa ukuba uya kukhetha ngokucacileyo:

1. Ngaba ndiyawafuna amacebiso asezantsi e-adsorption?

Ulwelo lwe-viscous oluqulethe i-detergent phakathi, nokuba yi-glycerol, okanye ugxininiso oluphezulu lwezisombululo zeprotheyini, i-adsorb iingcebiso eziqhelekileyo, ezikhokelela ekunciphiseni ukuchaneka kwemibhobho okanye ukukhupha okuguquguqukayo Ukuze uthintele intsalela yodonga olujingayo olujingayo, sonke sikwanazo iingcebiso zabo ezincinci. ezifana prewetting, nto leyo ebangela udonga lwangaphakathi incam ukwenza umaleko ifilimu elulwelo;Yithi i-snip umlomo we-tip ukuququzelela ukususwa xa uthatha i-glycerin Kwaye ngoku, kufuneka sikhethe iingcebiso eziphantsi ze-adsorption zingatshintshwa ngokugqibeleleyo, ngaphandle kweesampuli eziphezulu ze-viscosity, imfuno yokulandelela kunye neesampuli ezixabisekileyo nazo zinganeliseka ngokugqibeleleyo.

2. Kufuneka kusetyenziswe nini iingcebiso zekhatriji?

Xa i-cigarette efana ne-filter tip yongezwa kwisiphelo esiphezulu se-tip, isampuli yepayipi ayikwazi ukungena ngaphakathi kwi-pipette ngokuthanda, kunye neesampuli eziguquguqukayo, ezinokonakala umngcipheko wokungcola kunye nokubola kwepipette kunokunciphisa kakhulu, kunye akukho nkxalabo yokulangazelela okubangelwa kukuphatha kakubi;Okubaluleke ngakumbi, iingcebiso zokucoca ikhatriji zinokunqanda isampulu kwisampulu yosulelo lomnqamlezo, olusebenza ngakumbi kuvavanyo lwe-RNA apho ukosuleleka kuyoyikwa.

3. Ngaba iingcebiso zokupakisha ziya kuba yeyona ndlela iphambili?

Iimfumba luhlobo olutsha lokupakisha ngaphandle kwengxowa, ibhokisi, kunye nokuzaliswa kwakhona apho iipleyiti ezininzi zeengcebiso zibekwe kwinqaba, kwaye sithatha umaleko weentloko zepipette ezipakishwe kwibhokisi eqhelekileyo ukupakisha ngokukhawuleza iingcebiso ngaphandle kokuzichukumisa Kulunge kakhulu. kunye nokonga ixesha lokusebenza;Ukongeza, le ngcebiso idinga indawo yokugcina encinci kwaye inciphisa kakhulu ukusetyenziswa kweeplastiki kwaye ihambelana nokusingqongileyo Okwangoku, iilebhu zangaphandle ziye zasetyenziswa ngokuqhelekileyo, kwaye nangona umlinganiselo wale fomu uhlala uncinci ekhaya, kufuneka ube ngumkhwa omkhulu kwi-labhoratri yangaphandle. ixesha elide.

4. Yakhethwa njani ingcebiso ezenzekelayo?

Rhoqo ukhethe incam yoqobo yendawo yokusebenza ngokuthe ngqo xa singafuni ukukhathaza, kodwa ukuba ufuna ukufumana ingcebiso ezenzekelayo eqhuba ngcono, ungalibali i-labio.
