Hujayra madaniyati biologik tadqiqotlar uchun muhim texnik vosita bo'lgan hujayra klonlash texnologiyasi deb ham ataladi. Erlenmeyer chayqaladigan kolbalar hujayra madaniyati jarayonida qo'llaniladigan maxsus sarflanadigan materialdir. erlenmeyer silkituvchi flasks ning xususiyatlarini va foydalanish bo'yicha ehtiyot choralarini tushunish hujayra madaniyati ishining zaruriy shartidir. erlenmeyer chayqaladigan kolbalar odatda BPA bo'lmagan shaxsiy kompyuter materialidan yoki PETG materialidan in'ektsiya cho'zilgan shamollash texnologiyasidan tayyorlanadi va quyidagi xususiyatlarga ega:
1. 8L va 5L erlenmeyer chayqaladigan shisha qopqoqlarining havo o'tkazuvchan membrana maydoni shunga o'xshash mahsulotlarnikidan kattaroqdir, bu hujayralarning yuqori zichlikdagi madaniyati uchun mos keladi. Ish hajmi umumiy hajmning 60-80% gacha to'ldirilishi mumkin va bir xil hajmdagi silkituvchi kolbalarning hujayra chiqishi yuqoriroqdir.
2. 2,8 l erlenmeyerli silkituvchi kolbaning tiqilib qolgan yoyi dizayni haddan tashqari tabiiydir. Darboğazning o'lchami samarali gaz almashinuvi maydonini ta'minlaydi va bir qo'l bilan ishlash uchun ham qulaydir.
3. 5L erlenmeyer chayqaladigan kolba ergonomik tarzda ishlab chiqilgan tutqich bilan jihozlangan bo'lib, u shaker shishasini olish va suyuqlikni o'tkazish uchun qulaydir.
4. Shaker shishasining standart mahsuloti 0,2 mkm sterilizatsiya va ventilyatsiya bilan jihozlangan. Bundan tashqari, suyuqlikni aseptik tarzda o'tkazishni osonlashtirish uchun suyuqlik o'tkazgich qopqog'i ixtiyoriydir va suyuqlik o'tkazish uchun mos bo'lgan shisha qopqog'i ham mijozning jarayon talablariga muvofiq sozlanishi mumkin.
5. Shisha qopqog'ining nafas oluvchi membranasining hidrofobik dizayni suyuqlik bilan aloqa qilgandan so'ng nafas oluvchi membrananing muhrlanishi va nafas olish qobiliyatiga ta'sir qilmaydi.
erlenmeyer silkituvchi kolbalar hujayra madaniyati uchun shaker bilan ishlatilishi kerak. Foydalanish vaqtida erituvchi chayqaladigan kolbaning 30-40% dan oshmasligi kerak. Madaniyat jarayonida aylanish tezligini nazorat qilishga e'tibor bering. Umumiy boshlanish tezligi aniq vaziyatga qarab 75-125 RPM. . Havo ko'ylagili shakerlar haroratni nazorat qilishga, suv ko'ylagili shakerlar esa suv darajasiga e'tibor berishlari kerak.
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.
