Intuthuko esheshayo emkhakheni wesayensi yempilo yenze ubuchwepheshe be-cell culture busetshenziswe kabanzi. Amaflaski empucuko yeseli kukhona okusebenzisekayo okufanele amaseli esilinganiso esimaphakathi kanye nesiko lamathishu kulabhorethri. Amakepisi ale nto esetshenziswayo ahlukaniswe abe izinhlobo ezimbili: amakepisi ama-vent namakepisi avaliwe. Yiziphi izici zamakepisi we-vent?
Amaflask e-cell culture anekepisi yokukhipha umoya asetshenziswa kakhulu endaweni ene-carbon dioxide. Isivalo se-vent sakhiwe ulwelwesi oluphefumulayo kanye nesivalo sebhodlela. I-membrane ephefumulayo iwuhlobo olusha lwe-polymer engangeni manzi. Mayelana nenqubo yokukhiqiza, izidingo zobuchwepheshe ze-membrane ezingangeni manzi neziphefumula ziphakeme kakhulu kunezinto ezijwayelekile ezingangeni manzi; ngokombono wekhwalithi, ulwelwesi olunganamanzi nokuphefumula alutholakali kwezinye izinto ezingangeni manzi. Ukumelana nezinga lokushisa eliphezulu, ukumelana nokushisa okuphansi, ukumelana nokugqwala, ukunganamatheli, ukugcotshwa okuphezulu nezinye izici. . Ubukhulu be-pores bungavumela umhwamuko wamanzi ukuba udlule kahle, kodwa hhayi ama-molecule wamanzi, ngakho-ke lo mkhiqizo unomsebenzi wokungangeni kwamanzi nokuphefumula. Isembozo esiphefumulayo singavumela i-carbon dioxide endaweni ukuthi ingene ebhodleleni lesikwele le-cell culture, futhi inikeze izimo zegesi ezidingekayo ukuze amangqamuzana akhule. ekungeneni esitsheni nasekungcoliseni amaseli. Uketshezi olusebhodleleni ngeke luthinte ukusebenza kwalo kwesithiyo se-microbial kanye nomthelela wokungenisa umoya ngemva kokuthi luthinte ulwelwesi oluphefumulayo. Izikhungo zocwaningo zingayisebenzisa ngokuzethemba.
amaflask amasiko wamaseli
The breathable membrane on the cell culture flasks cap also has a sterilization function, which can prevent bacteria from entering the container and polluting the cells. The liquid in the bottle will not affect its microbial barrier performance and ventilation effect after it contacts the breathable membrane. Research institutions can use it with confidence.
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.
