Sarum plazmadan fibrinogenni olib tashlaganidan keyin kolloid suyuqlikni anglatadi. Odam va hayvonlarning sarumi kasalliklarni tashxislashda yordam berish uchun turli xil serologik testlar uchun keng qo'llaniladi. Sarum odatda maxsus sarum idishlarida -5 ° C dan -20 ° C gacha saqlanadi. Sarum saqlash harorati bo'yicha shunday qattiq talablarga ega, shuning uchun uni saqlash idishi sifatida media shisha qanday xususiyatlarga ega?
1. Media shishasining materiali asosan shaffof poliesterdan (PET) tayyorlanadi. Ushbu material toksik bo'lmagan va baxtsiz bo'lib, shaffofligi yuqori, past haroratga yaxshi qarshilik, yaxshi zarba qarshiligi va ko'pchilik kislota va gidroksidi erituvchilarning korroziyasiga bardosh bera oladi, bu esa sarumni kriyosaqlash talablariga to'liq javob beradi.
2. Media shishasining shakli oddiy suyuq plastik shishadan farq qiladi, lekin kvadrat shaklga mo'ljallangan. Ushbu dizayn ergonomik va sarumni tushunish va saqlash oson.
3. Elektron nurli sterilizatsiyadan so'ng, DNase, RNase va issiqlik manbai yo'q. Sarum hujayra o'sishi uchun asosiy oziq moddasi bo'lib, zardobning tozaligi va bepushtligini ta'minlash hujayra o'sishining asosiy shartidir. Shuning uchun media shisha DNase, RNase va pirogen talablarini qondirish uchun maxsus sterilizatsiya qilinadi.
4. Shishaning tanasi o'lchovga ega va turli xil texnik xususiyatlar ixtiyoriydir. Sarumning o'ziga xos hajmini kuzatishni osonlashtirish uchun media shishasining shisha tanasi odatda shkala bilan belgilanadi. Umumiy spetsifikatsiyalar 250ml, 500ml, 1000ml va turli spetsifikatsiyalar sarum turi va ishlatilishiga qarab tanlanishi mumkin.
Yuqoridagilar media shishasining xususiyatlari. Shuni ta'kidlash kerakki, media shishani yuqori harorat va yuqori bosim bilan sterilizatsiya qilish mumkin emas. U faqat sarum yoki reagentlarni saqlash uchun ishlatilishi mumkin va uni isitish idishi sifatida ishlatib bo'lmaydi.
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.
