Hujayra fabrikalariasosan katta hajmdagi hujayra madaniyati uchun ishlatiladi. Hujayralar atrof-muhitga yuqori talablarga ega, masalan, harorat, namlik, osmotik bosim, pH qiymati va boshqalar. Shuning uchun bunday cell sarf materiallari xom ashyoga ham yuqori talablarga ega.
Birinchisi shaffoflik. Hujayra madaniyati jarayonida istalgan vaqtda hujayralarning o'sish holatini tushunish va hujayra ko'payishiga qarab tegishli tuzatishlar kiritish kerak. Shuning uchun hujayra zavodining xom ashyosi shaffoflik talablariga javob berishi kerak, shuning uchun tadqiqotchilar hujayralar o'sishini kuzatish uchun qulay bo'lishi kerak.
Ikkinchisi - materiallarning mosligi. Ushbu sarflanadigan materialning xom ashyolari odatda USP VI sinfidagi tibbiy polimer materiallari talablariga javob beradi. Tibbiy polimer materiallari deganda insonning ichki organlari, tashqi organlari, farmatsevtik dozalash shakllari va tibbiy asboblarni ishlab chiqarish uchun ishlatiladigan polimer materiallar tushuniladi va ularning manbalari tabiiy biopolimer materiallari va sintetik biopolimer materiallarini o'z ichiga oladi. AQSh plastik tasniflash testida USP Class I-USP VI sinfining 6 darajasi mavjud va AQSh tibbiy plastmassasining oltinchi darajasi sifatida baholangan plastmassa juda keng qamrovli va qat'iy sinov o'rnatilganligini anglatadi. Uning sinov elementlariga tizimli toksiklik testi (sichqoncha), intradermal reaktsiya testi (quyon) va implantatsiya testi (quyon) kiradi. 6-darajali barcha turdagi tibbiy xom ashyo uchun oltin standart va tibbiy asbob-uskunalar ishlab chiqaruvchilar uchun juda yuqori sifatli tanlovdir.
hujayra fabrikasi USP VI toifali tibbiy polimer materiallarini tanlashining sababi shundaki, xom ashyo bu nav yuqori tozalikka ega, bu tayyor mahsulotning shaffofligini ta'minlaydi va yopishqoq hujayralarning adsorbsiyasiga ko'proq yordam beradi.
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.
