Is cill a úsáidtear go coitianta i bpróiseas shaothrúcháin na gceall é an fleascáin chroith erlenmeyer. Tá sé oiriúnach go príomha le haghaidh cultúr cille fionraí lánaimseartha, ullmhúchán meánach nó stórála, agus is féidir é a úsáid le cultúir mór-acmhainne shaker.
Cell cultúr éilíonn ceanglais chomhshaoil ard, mar shampla steiriúlacht, teocht oiriúnach, pH, agus áirithe. coinníollacha cothaitheacha. Ní mór na coinníollacha seo a bhaint amach le cabhair ó erlenmeyer fleascáin chroith. Mar sin, tá ceanglais dhian ag erlenmeyer shake fleasks ó ábhar go próiseas déantúsaíochta. erlenmeyer shake fleasks go ginearálta úsáid ábhair ríomhaire saor ó bisphenol agus ábhair PETG, agus glacann an phróiseáil próiseas múnlaithe stráice-séideadh instealladh aon-chéim, ar a dtugtar freisin próiseas táirgthe buille stráice insteallta aon-chéim. . Is é a phrionsabal oibre ná an bán múnlaithe a instealladh ar dtús le meaisín múnlaithe insteallta, an parison te a shíneadh go fadaimseartha, agus ansin pas a fháil san aer comhbhrúite chun é a shíneadh go cliathánach chun táirge a fháil ar an gcruth céanna leis an gcuas múnla.
An t-instealladh , síneadh, agus próisis mhúnlú buille den mhodh próiseála seo i gcrích in ord ar threalamh amháin. Is féidir múnlú ardluais a bhaint amach gan an preform a théamh arís agus arís eile. Déantar na codanna próiseas is casta a chaitheamh i leataobh agus úsáidtear an struchtúr próisis is optamaithe. Táirgeadh cobhsaí táirgí a bhaint amach go díreach, feabhas a chur ar ráta cáilithe na dtáirgí, agus teicneolaíocht a shábháil ar fhuinneamh. teagmháil agus tightness leis an caipín buidéal, agus friotaíocht brú níos mó, a leagann an bunús le haghaidh dul chun cinn rianúil obair chultúir cille.
The erlenmeyer shake flasks produced by the injection stretch-blow production process has a smooth and round mouth, better contact and tightness with the bottle cap, and more pressure resistance, which lays the foundation for the smooth progress of cell culture work.
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.
