Fleascáin chroith Erlenmeyeratá ina gcultúr cille tábhachtach inchaite. Roinntear iad i bhfleascáin chroith erlenmeyer triantánacha agus i bhfleascáin chroith erlenmeyer ard-éifeachtúlachta de réir a dtoilleadh agus a gcruth. Is iad seo a leanas a dtréithe:

Fleascán croiththeora erlenmeyer triantánach: Go ginearálta is beag toilleadh an fhleascáin chroith cille seo, idir 125ml-1000ml. Tugtar fleascán croith cónúil air freisin. Tá sé déanta as polycarbonate (PC) nó PETG. Tá dearadh cruth triantánach uathúil aige. Is féidir leis an bpípéad nó an scraper cille cúinne an bhuidéil a bhaint amach níos éasca, rud a fhágann go bhfuil an oibríocht chultúir cille níos áisiúla. Úsáidtear é go príomha le haghaidh saothrú línte cille feithidí le riachtanais ocsaigine níos airde. I gcomparáid le hábhair inchaite cosúil le monarchana cille agus fleascáin spinner cille, tá an limistéar cultúir cille níos lú, agus is uirlis cultúir cille eacnamaíoch é.

Fleascáin chroith erlenmeyer ard-éifeachtúlachta: Tá cumas mór ag an gcineál seo de fhleascán croith erlenmeyer agus is é oiriúnach do chultúr cille ard-dlúis. Is féidir an méid oibre a líonadh go 60-80% den toirt iomlán, agus tá an toradh cille den toirt céanna de fhleascán croith níos airde. Tá hanla atá deartha go heirgeanamaíochta sa fhleascán croith 5L erlenmeyer chun tógáil an chroitheora agus aistriú leachta a éascú. Tá dearadh stua an scrogaill ró-nádúrtha, agus ráthaíonn méid an scrogaill spás malartaithe gáis éifeachtach agus tá sé áisiúil freisin d'oibríocht aon-láimh.

Is iad seo thuas tréithe an dá erlenmeyer. éagsúla. Is é an rud céanna go bhfuil an dá fhleascán croith marcáilte le scála ar an gcorp buidéal chun breathnú ar chumas an mheáin chultúir a éascú. I roghnú caipíní buidéil, tá caipín vent steiriúil 0.2μm feistithe go ginearálta, agus is féidir caipín aistrithe leachtach a roghnú freisin chun aistriú aiseiptigh leacht a éascú.

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.
