Iimveliso
I-Trimethylol aminomethane
Sebenzisa
① Umbindi wefosfomycin, usenokusetyenziswa njenge vulcanization accelerator, izinto zokuthambisa (cream, lotion), imineral oil, parafini emulsifier, biological buffer.
② Isetyenziswa njenge-asidi yokufunxa irhasi, ukulungiswa kwe-buffer, i-surfactant, i-emulsifier kunye ne-accelerator.Ikwasetyenziswa kwi-organic synthes.
Indlela yokuvelisa
Dissolve Tris ngexabiso elincinci lamanzi abilayo kabini (300-500ml), yongeza i-HCl, ulungelelanise i-pH kwi-7.6 nge-HCl (1N) okanye i-NaOH (1N), kwaye ekugqibeleni wongeze amanzi aphindwe kabini kwi-1000ml.Olulwelo lulwelo olugciniweyo, olugcinwe efrijini kwi-4℃.
Qaphela: Ixabiso le-PH le-Tris-Hcl liyahluka ngeqondo lokushisa, ngoko kufuneka lilinganiswe kwiqondo lokushisa, ngoko ke iziphumo ezilinganisiweyo zithembeke ngakumbi.
Uphawu lokubhufa
I-Tris isiseko esibuthathaka kunye ne-pKa ye-8.1 kwindawo yokushisa (25℃).Ngokwenkcazo-buffering ithiyori, uluhlu olusebenzayo lwe-buffering lwe-Tris buffers luphakathi kwe-pH7.0 kunye ne-9.2.
I-pH yesisombululo samanzi se-Tris base imalunga ne-10.5, kwaye i-buffer yexabiso le-pH inokufumaneka ngokudibanisa i-hydrochloric acid ukulungisa ixabiso le-pH kwixabiso elifunwayo.Nangona kunjalo, ingqalelo kufuneka ihlawulwe kwimpembelelo yobushushu kwi-pKa ye-Tris.Idigri, ixabiso le-PH lehle nge-0.03.
I-1M Tris-HCl 6.8 kunye ne-1.5M Tris-HCl 8.8 zezona zisetyenziswa ngokuqhelekileyo kwi-SDS-PAGE.
Ngelixa i-TAE, i-TBE kunye nezinye ii-reagents ezenziwe kwi-Tris zezona zisetyenziswa ngokuqhelekileyo kwi-DNA electrophoresis, i-TE (pH8.0) isetyenziselwa ukuchithwa kwe-DNA.(TE yiTris kunye ne-EDTA.)
I-Tris buffers ayisetyenziswanga nje ngokubanzi njengezinyibilikisi ze-nucleic acids kunye neeproteni, kodwa ikwanosetyenziso oluninzi olubalulekileyo.I-Tris isetyenziselwa ukukhula kwekristale yeprotheni phantsi kweemeko ezahlukeneyo ze-pH.Amandla e-ayoni aphantsi e-Tris buffer angasetyenziselwa ukwakhiwa kwemicu ephakathi ye-lamin kwi-C. elegans.I-Tris ikwangomnye wamacandelo aphambili eprotein electrophoresis buffers.Ukongeza, i-Tris yindawo ephakathi kulungiselelo lwe-surfactants, i-vulcanization accelerators, kunye namanye amachiza.I-Tris ikwasetyenziswa njengomgangatho wetitration.
Ngendlela yemifanekiso kunye nesicatshulwa, inokubandakanya ulwazi lwemveliso, iinkonzo kunye neenzuzo.Iyakwazi ukuya ngaphaya kwemveliso ukongeza umxholo othile (iinkxalabo zabathengi, iinkxalabo, njl.), ukukhuselwa kwendalo, iisampuli zamahhala, njl.
1. Iisampulu zivavanywa ngaphandle kwentlawulo ukuqinisekisa ukusetyenziswa okuqhelekileyo kwabathengi.
2. Ngokwemfuno yabathengi abahlukeneyo, encinci ukuya kwi-100g, enkulu kwiitoni zemibhobho, inokuhlangabezana neemfuno zokupakisha.
3. Imiqathango yentlawulo eguquguqukayo, ukudluliselwa kwefowuni okanye ukwamkelwa (kuhlangatyezwana neemfuno zolwamkelo)
4. Ukuthutha ngokukhawuleza, ngosuku olufanayo okanye ngosuku olulandelayo lunokuhanjiswa, yonke inkqubo yokulandelela ulwazi lwe-logistics, ukuqinisekisa ukusetyenziswa kwabathengi ngexesha elifanelekileyo.
5. Inkonzo egqwesileyo emva kokuthengisa, isigulane kunye nokunyamekela ukusombulula zonke iintlobo zeengxaki ezinokuthi zenzeke, njengeengxaki zekhwalithi, ukusebenzisana ngokupheleleyo nabathengi ukujongana ngokukhutheleyo, musa ukuphepha uxanduva kunye nokuphendula okungahambiyo.
6. Iqela eligqwesileyo, ukusebenza ngokufanelekileyo kunye nolwazi lobuchwephesha benza ukuba abathengi bangaqinisekanga kuphela malunga neemveliso zethu, kodwa bavakalelwa kukuba iqela lethu linokwethenjelwa.
7. Ilungelo lokuthumela ngaphandle elizimeleyo ukwakha imarike yamazwe ngamazwe kunye nempembelelo yophawu lwehlabathi.
8. Ukunyaniseka, ileta esekwe, iminyaka engama-20 yembali yenkampani kunye nodumo oluhle, vumela abathengi bakhululeke ngakumbi, bazuze ngokulinganayo kwaye baphumelele, intsebenziswano enyanisekileyo.
