Mae'r : a ddefnyddir ar gyfer tyfu celloedd ymlynol. Rhaid i dwf celloedd o'r fath gael arwyneb cynnal y gellir ei gysylltu, a gall y celloedd dyfu ac atgenhedlu ar yr wyneb hwn trwy ddibynnu ar ffactorau ymlyniad sy'n cael eu secretu ganddynt eu hunain neu a ddarperir yn y cyfrwng diwylliant. Mae wyneb y botel wedi cael triniaeth addasu arbennig i gyflwyno grwpiau hydroffilig. Pwrpas hyn yw cynyddu perfformiad adlyniad wyneb y botel, sy'n fwy addas ar gyfer twf celloedd. Nid yw twf y celloedd hyn yn dibynnu ar wyneb y gefnogaeth ac mae'n tyfu mewn ataliad yn y cyfrwng diwylliant. Gelwir celloedd o'r fath yn gelloedd crog. Megis lymffocytau. Yn gyffredinol, mae gan bolystyren strwythur pen-i-gynffon, mae'r brif gadwyn yn gadwyn garbon dirlawn, ac mae'r grŵp ochr yn gylch bensen cyfun, sy'n gwneud y strwythur moleciwlaidd yn afreolaidd, yn cynyddu anhyblygedd y moleciwl, ac yn gwneud PS yn ddi- polymer llinellol crisialog. Mae ganddo rywfaint o hydroffobigedd, felly gellir defnyddio'r wyneb ar gyfer diwylliant celloedd crog heb driniaeth arbennig. wedi'i wneud o ddeunydd polystyren gradd feddygol gyda thryloywder uchel. Yn ôl gwahanol brosesau trin wyneb, mae wedi'i rannu'n ddau fath: fflasgiau diwylliant cell hydroffilig a hydroffobig.
Mae'r uchod yn ddau fath o fflasgiau diwylliant celloedd, sy'n addas yn bennaf ar gyfer graddfa ganolig. meithriniad celloedd a meinwe yn y labordy. Mae'r dyluniad tagfa eang yn hwyluso'r pibed a'r sgrafell gell i gysylltu â'r arwyneb twf. fflasg diwylliant celloedd hydroffobig
Hydrophobic cell culture flask: used for the cultivation of suspension cells. The growth of these cells does not depend on the surface of the support and grows in suspension in the culture medium. Such cells are called suspension cells. Such as lymphocytes. Polystyrene generally has a head-to-tail structure, the main chain is a saturated carbon chain, and the side group is a conjugated benzene ring, which makes the molecular structure irregular, increases the rigidity of the molecule, and makes PS a non-crystalline linear polymer. It has a certain degree of hydrophobicity, so the surface can be used for suspension cell culture without special treatment.
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.
