Erlenmeyer shake flasksziyi-cell culture ebalulekile ezidlekayo. Ahlukene abe amaflaski angamanxantathu e-erlenmeyer shake kanye namaflaski e-erlenmeyer ashukumisayo asebenza kahle kakhulu ngokuya ngomthamo nokuma kwawo. Izici zabo zimi kanje:
Triangular erlenmeyer shake flask: Umthamo wale flask shake yeseli ngokuvamile mancane, kusukela ku-125ml-1000ml. Ibizwa nangokuthi i-conical shake flask. Yenziwe nge-polycarbonate (PC) noma i-PETG. Inomklamo oyingqayizivele womumo ongunxantathu. I-pipette noma i-cell scraper ingafinyelela ekhoneni lebhodlela kalula, okwenza ukusebenza kwesiko lamaseli kube lula kakhulu. Isetshenziselwa ikakhulukazi ukutshala imigqa yamaseli ezinambuzane ezinezidingo eziphezulu ze-oxygen. Uma kuqhathaniswa nezinto ezisetshenziswayo ezifana namafekthri amaseli nama-cell spinner flasks, indawo ye-cell culture incane, futhi iyithuluzi elinomnotho le-cell culture.
Amaflaski ashukumisayo e-erlenmeyer asebenza kahle kakhulu: Lolu hlobo lweflask ye-erlenmeyer shake inomthamo omkhulu futhi ilungele isiko lamaseli aphezulu kakhulu. Ivolumu yokusebenza ingagcwaliswa ku-60-80% wevolumu ephelele, futhi isivuno seseli somthamo ofanayo we-shake flask siphezulu. I-5L erlenmeyer shake flask ifakwe isibambo esiklanywe ngendlela efanele ukuze kube lula ukuthathwa kwe-shaker kanye nokudluliselwa koketshezi. Idizayini ye-arc ye-bottleneck ingokwemvelo ngokweqile, futhi usayizi we-bottleneck uqinisekisa indawo esebenzayo yokushintshanisa igesi futhi kulula ukuyisebenzisa ngesandla esisodwa.
Okungenhla yizimpawu zokubili okuhlukene erlenmeyer shake flasks. Okufanayo ukuthi ama-shake flasks amabili amakwe ngesikali emzimbeni webhodlela ukuze kube lula ukubhekwa komthamo we-culture medium. Ekukhetheni izikepisi zamabhodlela, ikepisi eliyinyumba elingu-0.2μm livamise ukufakwa, kanye nesivalo sokudlulisa uketshezi singaphinda sikhethwe ukuze kube lula ukudluliswa kwe-aseptic yoketshezi.
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.
