Erlenmeyer shake flasks asetshenziswa kakhulu emkhakheni we-microbiology kanye ne-cell biology. Angasetshenziswa nama-shaker amasiko amakhulu futhi afanele isiko lokumiswa ngokugcwele, ukulungiswa okuphakathi noma ukugcinwa. Amaseli anezidingo eziphakeme kakhulu ngendawo ezungezile, ngakho-ke iyiphi impahla evame ukusetshenziselwa erlenmeyer shake flasks?
Into ebonakalayo ye the erlenmeyer shake flask ngokuyinhloko ipulasitiki, ikakhulukazi polycarbonate (PC) impahla kanye PETG impahla. I-Polycarbonate (i-PC kafushane ngesiNgisi) iyi-polymer enesisindo samangqamuzana aphezulu equkethe amaqembu e-carbonate ochungechungeni lwamangqamuzana. Ayinambala futhi isobala, ayikwazi ukumelana nokushisa, imelana nokushayisana, ayinqandeli ilangabi, izinga le-BI, futhi inezici ezinhle zomshini emazingeni okushisa ajwayelekile okusebenza. Inezinhlobonhlobo zezicelo embonini yezinto zokwakha, ukukhiqiza izimoto, imishini yezokwelapha, i-aerospace, ukupakisha, amalensi optical neminye imikhakha. Ingasetshenziselwa izinkomishi zokwelapha, amashubhu, amabhodlela, izinto zamazinyo, iziqukathi ezenza imithi kanye nemishini yokuhlinza, futhi Ize Isetshenziswe njengezitho zokwenziwa njengezinso zokwenziwa kanye namaphaphu okwenziwa.
PETG iyi-copolyester esobala, engeyona i-crystalline. Imikhiqizo yayo isobala kakhulu futhi inokumelana nomthelela omuhle kakhulu. Ifaneleka ikakhulukazi ukwenza imikhiqizo esobala enezindonga eziwugqinsi. Inezakhiwo ezinhle kakhulu zokucubungula nokubumba futhi ingaklanywa kunoma yisiphi isimo ngokuvumelana nenhloso yomklami. Ingase isebenzise i-extrusion yendabuko, umjovo, ukubumba igalelo kanye nezindlela zokubumba amabhamuza, ezingasetshenziswa kabanzi emakethe yamapuleti, amashidi, amafilimu anciphayo asebenza kahle kakhulu, amabhodlela nezinto ezinephrofayili. Ngesikhathi esifanayo, inokusebenza okuhle kakhulu kwesibili kokucubungula futhi ingasetshenziselwa ukuguqulwa komshini Okuvamile.
Polycarbonate (PC) kanye nezinto ze-PETG ziyizinto ezisetshenziswa kakhulu erlenmeyer shake flasks. Kungakhathaliseki ukuthi iyiphi impahla ekhethiwe, kufanele ihlangabezane nezidingo ezihlukahlukene zesiko lamaseli ukuze kuqinisekiswe ukuqhubeka kahle kwesiko lamaseli.
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.
