laboratoriyada o'rta miqyosdagi hujayra to'qimalari madaniyati uchun mos bo'lgan sarf materialidir. Sarflanadigan materialning sifati tajriba jarayoni bilan bog'liq bo'lib, hujayralarning o'sishi va ko'payishi uchun juda muhimdir. Ushbu sarflanadigan materialni tanlashda quyidagi omillarni hisobga olish kerak:1. To'siqning kengligi va shakli: Hujayralarni etishtirishda u hujayralarni pipetlash va yig'ib olishni o'z ichiga oladi. Keng darboğazning dizayni spatula yoki pipetkani shishaga qulayroq kiritish imkonini beradi va operatsiyani osonlashtiradi. Hujayralarni parchalash va keyin hujayralarni yig'ish uchun turli fermentlardan foydalanish ham mavjud. Egri bo'yin dizayni o'lik burchak qoldirmaydi, bu madaniy muhitni eksport qilish uchun qulaydir.hujayra kulturasi
2. Sterilizatsiyani kafolatlash darajasi: hujayra o'sishi atrof-muhitga nisbatan qat'iy talablarga ega, shuning uchun hujayra o'sishiga ta'sir qilmaslik uchun hujayra madaniyati flakonlari ma'lum bir sterillik darajasiga yetishi kerak. Odatda, sanoatda SAL10-6 talab qilinadi va sterilizatsiya qilinmaslik darajasi 100% dan oshmaydi. 10 000 tadan bittasi.
3. Madaniyat shishasi ostidagi havo oqimi: hujayra madaniyati barqaror va barqaror bo'lishi kerak. Odatda shishaning pastki qismida havo aylanishini ta'minlash va harorat muvozanatini saqlash uchun shamollatuvchi spikerlar mavjud.
4. Bardoshli dizayn: Bu asosan ishlov berish materiallari va shishaning devor qalinligiga tegishli. Yaxshi materiallar va devor qalinligi yaxshi mexanik qarshilik ko'rsatishi mumkin.
5. Ko'rgazmali TC bilan ishlov berish: Ushbu sarflanadigan material asosan yopishgan hujayralarni etishtirish uchun ishlatiladi va sirt adsorbsion ko'rsatkichlariga yuqori talablarga ega. Odatda, hujayralar shisha yuzasiga yaxshi yopishib olishini ta'minlash uchun u maxsus ko'rgazmali modifikatsiyadan o'tadi.

ni tanlashda e'tiborga olinishi kerak bo'lgan besh omil. Yuqori sifatli sarf materiallari muvaffaqiyatli tajriba uchun zaruriy shartdir. Sarflanadigan materiallarni tanlashda siz nafaqat narxni hisobga olishingiz, balki mahsulot sifatiga ham e'tibor berishingiz kerak.cell culture flask hujayra madaniyati kolbasi
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.
