Ukusebenza kahle okuphezulu erlenmeyer shake flask kuyisitsha esimise okukhethekile se-cell culture, esidlala indima ebalulekile esikweni lokumiswa kwamaseli ezincelisayo namaseli ezinambuzane. Mayelana nokukhethwa kwempahla, lokhu okusebenzisekayo kwenziwa nge-polycarbonate (PC) enokukhanya okuphezulu, ukumelana nomthelela oqinile, nokumelana nezinga lokushisa eliphakeme elingu-121°C.
PC iyi-polymer enesisindo samangqamuzana aphezulu equkethe i-carbonate. amaqembu ochungechungeni lwamangqamuzana. Ayinambala futhi isobala. Ngenxa yesakhiwo sayo esikhethekile, isiphenduke ipulasitiki yobunjiniyela ejwayelekile enezinga lokukhula ngokushesha phakathi kwamapulasitiki amakhulu amahlanu wobunjiniyela. Lapho impahla ye-PC ihlanganiswa, i-BPA iyengezwa, kodwa ukuze kuvinjwe i-BPA ukuthi ithinte ukukhula kweseli, i-erlenmeyer shake flask esebenza kahle kakhulu isebenzisa i-PC engena-BPA ukuqinisekisa indawo enhle yokukhula kwamaseli.
Ngaphezu kwalokho, i Impahla ye-PC inezinto ezinhle zomshini, ubukhulu obuzinzile, nokukhasa okuncane, ngisho nangaphansi kwezimo zokushisa eziphezulu. Inkomba yokushisa ye-UL ethuthukisiwe ifinyelela ku-120~140℃ (ukuguga ngaphandle kwesikhathi eside nakho kuhle kakhulu), i-dielectric coefficient ingu-3.0-3.2, futhi ukumelana kwe-arc ngu-120s. Kuyimpahla ekahle yokukhiqiza izingxenye zikagesi nezikagesi. Kodwa-ke, le nto ilula ukubola lapho ivezwe emanzini ekushiseni okuphezulu, ngakho-ke kufanele kuqashelwe uma isetshenziselwa izinga lokushisa eliphezulu kanye nemvelo ephezulu yomswakama. Impahla ye-PC futhi inezici ezinhle zokucubungula futhi ingakhiwa ngokubumba umjovo noma ngokubumba i-extrusion kusetshenziswa okokusebenza okujwayelekile.
Impahla ye-PC iyinto evame ukusetshenziswa kakhulu yokucubungula ukusebenza ngempumelelo okuphezulu erlenmeyer shake flasks. Ngaphezu kwalokho, impahla ye-PETG ingasetshenziswa njengendlela yokucubungula izinto ezingavuthiwe zamaflasks ashukumisayo asebenza kahle kakhulu. Amakhasimende angakhetha ngokwezidingo ezahlukene.
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.
