Dve vrsti bučk celične kulture

je izdelan iz medicinskega polistirena z visoko prosojnostjo. Glede na različne procese površinske obdelave ga delimo na dve vrsti: hidrofilno in hidrofobno.: uporabljajo se za gojenje adherentnih celic. Rast takšnih celic mora imeti podporno površino, ki jo je mogoče pritrditi, celice pa lahko rastejo in se razmnožujejo na tej površini, tako da se zanašajo na pritrdilne faktorje, ki jih izločajo sami ali so na voljo v gojišču. Površina steklenice je bila podvržena posebni modificirani obdelavi za uvedbo hidrofilnih skupin. Namen tega je povečati sposobnost oprijema površine steklenice, ki je bolj primerna za rast celic.bučke za celično kulturo

: uporablja se za gojenje suspenzijskih celic. Rast teh celic ni odvisna od površine nosilca in raste v suspenziji v gojišču. Takšne celice imenujemo suspenzijske celice. Kot so limfociti. Polistiren ima na splošno strukturo od glave do repa, glavna veriga je nasičena ogljikova veriga, stranska skupina pa je konjugiran benzenski obroč, zaradi česar je molekularna struktura nepravilna, poveča togost molekule in naredi PS ne- kristalinični linearni polimer. Ima določeno stopnjo hidrofobnosti, zato se površina lahko uporablja za suspenzijsko celično kulturo brez posebne obdelave.Bučka za hidrofilno celično kulturo

Zgoraj sta dve vrsti bučk za celične kulture, ki sta primerni predvsem za srednje velike celična in tkivna kultura v laboratoriju. Zasnova širokega ozkega grla omogoča, da se pipeta in strgalo za celice dotakneta rastne površine.Hidrofobna bučka za celično kulturo

The above are two types of cell culture flasks, which are mainly suitable for medium-scale cell and tissue culture in the laboratory. The wide bottleneck design facilitates the pipette and cell scraper to contact the growth surface.

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.
