Erlenmeyerjeve stresalne bučke za suspenzijo celične kultureso vrsta potrošnega materiala, ki se običajno uporablja v celični kulturi. Delimo jih na dve vrsti: trikotne stresalne bučke in stresalne bučke velike prostornine glede na velikost in obliko celice. Oblika steklenice je sorazmerno posebna, zato je v tehnologiji predelave izbran enostopenjski postopek raztegovanja in raztezanja.
Erlenmeyerjeve stresalne bučke za suspenzijo celične kulture se uporabljajo predvsem za gojenje limfocitov, celic žuželk in drugih suspenzijskih celic. Rast takšnih celic ni odvisna od površine nosilca in raste v suspendiranem stanju v gojišču. Ker rast celic zahteva posebne pogoje, kot so okolje, temperatura, osmotski tlak, pH vrednost itd., so tudi zahteve glede kakovosti potrošnega materiala višje. , kar zahteva manjšo izrabo površine proizvodnega mesta, kompleksnejše oblikovne strukture, debelejše ali tanjše izdelke ter višje zahteve glede natančnosti kalupa in procesnih pogojev. Ta proces se začne od vbrizgavanja zarodne cevi izdelka do raztegljivega pihanja, na koncu pa je odstranjevanje končano v enem koraku, pri čemer se prihrani veliko dela, porabe energije in talnega prostora, kakovost in stabilnost izdelka pa sta višji. . Stresna bučka z suspenzijskimi celicami, proizvedena s tem postopkom, nima bliskavice, izliva, nekaj napak, ima pa tudi popolno ustje, dno, linijo šiva, večjo preglednost in večjo togost.
Proizvodni proces z enostopenjskim vbrizgavanjem in raztezanjem se ne uporablja samo za
, ampak se pogosto uporablja tudi v steklenicah za farmacevtsko embalažo, steklenicah za embalažo za hrano, steklenicah za kozmetično embalažo in nekaterih visokokakovostnih embalažnih steklenicah za vsakodnevne potrebe.suspension cell culture erlenmeyer shake flasks, but also widely used in pharmaceutical packaging bottles, food packaging bottles, cosmetic packaging bottles and some high-end daily necessities packaging bottles.
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.
