- ko'p qatlamli hujayra madaniyati sarflanadigan material bo'lib, odatda yopishgan hujayralarning keng miqyosli madaniyati uchun ishlatiladi. Sarf materiallari sifati hujayralarning o'sish holatiga bevosita ta'sir qiladi, shuning uchun ularning sifatini qanday nazorat qilish kerak?1. Xom ashyo: Hujayra zavodining xom ashyosi odatda polistirol bo'lib, xom ashyo USP VI sinf standartiga javob berishi kerak. USPVI darajasidagi tibbiy asbob-uskunalar sinovi tibbiy sohada plastik materiallarni va biofarmatsevtikada quvur liniyasi mahsulotlarini qo'llash uchun nisbatan qattiq sinovdir. Bu turli eksperimental spetsifikatsiyalarga javob beradigan klinik bo'lmagan laboratoriya tadqiqotidir.cell fabrikasi
2. Ishlab chiqarish muhiti: hujayralar o'sish muhitiga ayniqsa sezgir, shuning uchun sarf materiallarida endotoksin kabi hujayralar uchun zararli moddalar bo'lmasligi kerak, bu ularning ishlab chiqarish muhitiga yuqori talablarni qo'yadi. Sarf materiallari maxsus 10 000 toifali toza xonada ishlab chiqarilishi va qat'iy tekshiruvdan (planktonik bakteriyalar, cho'kindi bakteriyalar va to'xtatilgan zarrachalarni aniqlash) o'tishi va barqaror mahsulot sifatini ta'minlash uchun GMP ustaxonalariga muvofiq sifat menejmentini amalga oshirishi kerak.
3 . Ishlab chiqarish jarayoni: Bu tayyor mahsulotning tekisligi va muhrlanishi bilan bevosita bog'liq bo'lgan mahsulotni ishlab chiqarish jarayoniga tegishli. Hujayra zavodi inyeksion kalıplama jarayoni bilan ishlab chiqariladi va ishlab chiqarishdagi turli parametrlar qat'iy nazorat qilinishi kerak.
4. Sifatni tekshirish: Mahsulotni ishlab chiqarish tugallangandan so'ng, u turli xil sifat tekshiruvlaridan o'tishi kerak, masalan, sirt gidrofilligi sinovi, muhrlanish sinovi, bioxavfsizlik testi, fizik va kimyoviy xavfsizlik testi, mahsulotning amal qilish muddatini tekshirish, qadoqlashni tekshirish va hk. malakali bo'ladimi.
Yuqoridagilar yuqori sifatli hujayra zavodlari e'tibor berishlari kerak bo'lgan to'rt jihatdir. Bunga qo'shimcha ravishda, agar u ko'p qatlamli tuzilishga ega bo'lgan sarf moddasi bo'lsa, u qatlamlar orasidagi moslashuvning buzilmaganligini ham o'z ichiga oladi, bu mahsulotning zichligi bilan bevosita bog'liq.
The above are four aspects that high-quality cell factories need to pay attention to. In addition, if it is a consumable with a multi-layer structure, it also involves whether the fit between the layers is intact, which is directly related to the tightness of the product.
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.
