Erlenmeyer chayqaladigan kolbalarmuhim iste'mol qilinadigan hujayra madaniyati hisoblanadi. Ular sig‘imi va shakliga ko‘ra uchburchakli erlenmeyer chayqaladigan kolbalar va yuqori samarali erlenmeyerli silkituvchi kolbalarga bo‘linadi. Ularning xarakteristikalari quyidagicha:
Uchburchakli erlenmeyer chayqaladigan kolba: Bu hujayrali silkituvchi kolbaning sig'imi odatda kichik bo'lib, 125ml-1000ml gacha. U konussimon silkituvchi kolba deb ham ataladi. U polikarbonat (PC) yoki PETG dan tayyorlangan. U uchburchak shaklidagi noyob dizaynga ega. Pipetka yoki hujayra qirg'ichlari shishaning burchagiga osonroq etib borishi mumkin, bu hujayra madaniyatining ishlashini yanada qulay qiladi. U asosan kislorodga yuqori talablarga ega bo'lgan hasharotlar hujayralarini etishtirish uchun ishlatiladi. Hujayra zavodlari va hujayra yigiruvchi kolbalar kabi sarf materiallari bilan solishtirganda, hujayra madaniyati maydoni kichikroq va u tejamkor hujayra madaniyati vositasidir.
Yuqori samarali erlenmeyer silkituvchi kolbalar: Bu turdagi erlenmeyer silkituvchi kolbalar katta sig'imga ega va yuqori zichlikdagi hujayra madaniyati uchun javob beradi. Ish hajmi umumiy hajmning 60-80% gacha to'ldirilishi mumkin va bir xil hajmdagi silkituvchi kolbaning hujayra unumi yuqori bo'ladi. 5 l erlenmeyer chayqaladigan kolba chaykashni olish va suyuqlikni uzatishni osonlashtirish uchun ergonomik tarzda ishlab chiqilgan tutqich bilan jihozlangan. Darboğazning yoy dizayni haddan tashqari tabiiy bo'lib, to'siqning o'lchami samarali gaz almashinuvi maydonini kafolatlaydi va bir qo'l bilan ishlash uchun ham qulaydir.
Yuqoridagilar ikki xil erlenmeyer silkituvchi kolbalar xususiyatlari. Xuddi shu narsa, oziqlantiruvchi muhitning sig'imini kuzatishni osonlashtirish uchun ikkita silkituvchi kolba shishaning tanasida shkala bilan belgilanadi. Shisha qopqog'ini tanlashda odatda 0,2 mkm steril shamollatish qopqog'i bilan jihozlangan va suyuqlikni aseptik tarzda o'tkazishni osonlashtirish uchun suyuqlik o'tkazgich qopqog'ini ham tanlash mumkin.
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.
