Isiko lamaseli libizwa nangokuthi ubuchwepheshe be-cell cloning, okuyindlela yobuchwepheshe ebalulekile yocwaningo lwebhayoloji. I-erlenmeyer shake flasks iwukusetshenziswa okukhethekile okusetshenziselwa inqubo yesiko lamaseli. Ukuqonda izici ze-erlenmeyer shake flasks kanye nezinyathelo zokuphepha zokusetshenziswa kuyimfuneko yomsebenzi wosiko lweseli. Amaflaski e-erlenmeyer shake ngokuvamile enziwa ngempahla ye-PC engena-BPA noma impahla ye-PETG ngokusebenzisa ubuchwepheshe bokushaywa komjovo, futhi anezici ezilandelayo:
1. Indawo ye-membrane ye-air-permeable engu-8L kanye ne-5L ye-erlenmeyer shake flasks caps inkulu kunemikhiqizo efanayo, efaneleka isiko lokuminyana okuphezulu kwamaseli. Ivolumu yokusebenza ingagcwaliswa ibe ngu-60-80% wevolumu ephelele, futhi isivuno seseli sevolumu efanayo yama-shake flasks siphezulu.
2. Idizayini ye-arc ye-bottleneck ye-2.8 L erlenmeyer shake flask ingokwemvelo ngokwedlulele. Usayizi webhodlela uqinisekisa indawo esebenzayo yokushintshisana ngegesi futhi kulula ukuyisebenzisa ngesandla esisodwa.
3. I-5L erlenmeyer shake flask ifakwe isibambo esiklanywe ngendlela efanele, esilungele ukuthatha ibhodlela le-shaker nokudlulisa uketshezi.
4. Umkhiqizo ojwayelekile webhodlela le-shaker ufakwe inzalo engu-0.2μm kanye nokukhipha umoya. Ukwengeza, isivalo sokudlulisa uketshezi singakhethwa ukuze kube lula ukudluliswa kwe-aseptic koketshezi, futhi isivalo sebhodlela esifanele ukudluliswa koketshezi singenziwa ngokwezifiso ngokuya ngezidingo zenqubo yekhasimende.
5. Idizayini ye-hydrophobic ye-membrane ephefumulayo yekepisi yebhodlela akuthinti ukusebenza kokuvala kanye nokuphefumula kwe-membrane ephefumulayo ngemva kokuthintana noketshezi.
I-erlenmeyer shake flasks idinga ukusetshenziswa ne-shaker yesiko leseli. I-solvent akufanele idlule i-30% -40% ye-shake flask ngesikhathi sokusetshenziswa. Naka ukulawula isivinini sokujikeleza phakathi nenqubo yesiko. Isivinini sokuqala esijwayelekile ngu-75-125RPM, kuya ngesimo esithile. . Oshaker abagqoke amajakhethi omoya badinga ukunaka ukulawula izinga lokushisa, futhi abashaker abanejakhethi yamanzi badinga ukunaka izinga lamanzi.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
