I-ama-cell culture flasks yenziwe ngempahla ye-polystyrene yezinga lezokwelapha enokucaca okuphezulu. Ngokwezinqubo ezihlukene zokwelashwa kwendawo, ihlukaniswe yaba izinhlobo ezimbili: i-hydrophilic kanye ne-hydrophobic.
I-Hydrophilic cell culture flask: asetshenziselwa ukutshala amaseli anamathelayo. Ukukhula kwamaseli anjalo kufanele kube nendawo yokusekela engaxhunywa, futhi amaseli angakhula futhi akhiqize kabusha kule ndawo ngokuthembela ezintweni ezinamathiselwe ezifihliwe ngokwazo noma ezihlinzekwe endaweni yesiko. Ingaphezulu lebhodlela liye labhekana nokwelashwa okukhethekile kokuguqulwa ukwethula amaqembu e-hydrophilic. Inhloso yalokhu ukukhulisa ukusebenza kokunamathela kwendawo yebhodlela, efaneleka kakhulu ukukhula kwamaseli.
I-Hydrophobic cell Culture flask: isetshenziselwa ukutshala amaseli amisiwe. Ukukhula kwalawa maseli akuxhomekile ebusweni bokusekelwa futhi kukhula ngokumiswa endaweni yesiko. Amaseli anjalo abizwa ngokuthi ama-suspension cell. Njengama-lymphocyte. I-Polystyrene ngokuvamile inokwakheka kwekhanda kuye emsileni, iketango eliyinhloko iketango lekhabhoni eligcwele, futhi iqembu elisemaceleni liyindandatho ye-benzene ehlanganisiwe, eyenza ukwakheka kwamangqamuzana kube okungajwayelekile, kukhuphule ukuqina kwe-molecule, futhi kwenza i-PS ingabi i-polymer eqondile ye-crystalline. Inezinga elithile le-hydrophobicity, ngakho-ke indawo engaphezulu ingasetshenziselwa isiko lamaseli amisiwe ngaphandle kokuphathwa okukhethekile.
Okungenhla yizinhlobo ezimbili zamaflask e-cellculture, afaneleka kakhulu esikalini esimaphakathi. iseli kanye nesiko lamathishu elabhorethri. Umklamo obanzi we-bottleneck usiza i-pipette kanye ne-cell scraper ukuxhumana nendawo yokukhula.
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.
