ir izgatavots no medicīniskā polistirola materiāla ar augstu caurspīdīgumu. Atbilstoši dažādiem virsmas apstrādes procesiem to iedala divos veidos: hidrofilā un hidrofobā.: izmanto adherentu šūnu kultivēšanai. Šādu šūnu augšanai jābūt ar atbalsta virsmu, ko var piestiprināt, un šūnas var augt un vairoties uz šīs virsmas, paļaujoties uz piesaistes faktoriem, ko tās izdala pašas vai nodrošina barotnē. Pudeles virsma ir īpaši modificēta, lai ieviestu hidrofilās grupas. Tā mērķis ir palielināt pudeles virsmas adhēzijas veiktspēju, kas ir vairāk piemērota šūnu augšanai.šūnu kultivēšanas kolbas
Iepriekš minētās ir divu veidu šūnu kultūras kolbas, kas galvenokārt ir piemērotas vidēja mēroga audzēšanai. šūnu un audu kultūra laboratorijā. Plašais sašaurinājuma kakliņa dizains atvieglo pipetes un šūnu skrāpja saskari ar augšanas virsmu.Hidrofobās šūnu kultūras kolba
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.
