Laboratory Flasks muaj txiaj ntsig hom chemistry glassware muaj cov kua thiab ua kom sib tov, cua sov, txias, nag lossis daus, condensation, thiab lwm yam txheej txheem. Cov flasks - tseem hu ua science flask, chemistry flask, los yog a lab (lab flask)- Los ntawm ntau qhov ntau thiab tsawg, cov khoom siv, thiab kev siv.
Nquag siv hom chemistry flasks muaj xws li:
- Nitrogen khob
Lub npe: Kjeldahl flask
Kev Siv: Nws yog tsim rau kev tsom xam ntawm nitrogen hauv cov organic teeb meem hauv kev tshawb fawb txog kev ua liaj ua teb thiab cov chaw tshawb fawb, xws li kev zom cov tshuaj tiv thaiv thiab distillation ntawm ammonia. Feem ntau, ntau tshaj rau yog xav tau ntawm ib lub sijhawm.
2.Round-bottomed flask
Fractionation khob
Siv: Haum rau kev sib cais lossis kev sib cais ntawm qee cov organic tebchaw hauv chav kuaj.
Nta: Txhawm rau kom tsis txhob kub hnyiab ntawm lub raj mis thaum lub sijhawm distillation, cov kua nkag mus rau hauv cov yeeb nkab ceg thiab ntws mus rau hauv cov yeeb nkab condensing. Cov khoom uas kis tau los ntawm distillation cuam tshuam rau purity ntawm distillation thiab tsim.
3.Distillation hwj
Kev Siv: Nws yog siv rau cov kua distillation los yog fractionation, thiab nws yog feem ntau siv ua ke nrog condenser yeeb nkab, kua yeeb nkab thiab kua adapter. Nws tseem tuaj yeem sib sau ua ke lub tshuab hluav taws xob roj.
Nta: Vim yog qhov yuav tsum tau fractionate cov kua, muaj ib lub raj iav nyias nyias tawm me ntsis downward ntawm lub caj dab ntawm lub raj mis rau cov kua dej. Thaum lub hwj chim distillation yog cua sov los thaiv lub qhov ncauj ntawm lub raj mis, lwm lub raj yuav tsum tau txuas ntxiv.
4. Pear khob
Kev Siv: Siv rau cov evaporators teb los ua kom cov kua dej ntau ntxiv thiab ua kom hnyav evaporation. Cov txiaj ntsig organic teeb meem yuav ntws mus rau hauv qab ntawm lub raj mis pear kom pab tshem tawm thiab txo qhov poob.
5. Eggplant khob
Kev Siv: Nws yog qhov tsim nyog rau kev kuaj cov khoom tuab lossis rau kev txais lub raj mis. Nws tuaj yeem raug khawb ncaj qha nrog lub scraper nrog nws lub xub pwg nyom raws li cov khoom tuab tuab.
6.Multi-caj dab
Kev faib tawm: ob-caj dab, ncaj peb-hlawv, peb-caj dab, ncaj plaub-caj dab, thiab plaub-caj dab. Qhov chaw nres nkoj sab saud tuaj yeem siv ua ke nrog qee cov twj paj nruag uas txuas rau qhov sib cais funnel, txias, thiab tus pas ntsuas kub.
Siv: kua-kua lossis kua-kua reactor; gas tshuaj generator; distillation los yog fractionation kua.
