Namhlanje, makhe sazane nolu ndwendwe luhlala rhoqo elabhoratri –iflaski ye-Erlenmeyer!

uphawu

Umlomo omncinci, umphantsi omkhulu,

Imbonakalo yi-conical ene-flat-bottomed ene-cylindrical neck

Kukho izikali ezininzi kwibhotile ukubonisa umthamo onokuthi uwubambe.usebenzise

1. I-conical flask isetyenziswa ngokubanzi kwimifuniselo yetitration.Ukuze uthintele i-titrant ukuba ingachaphazeli ngaphandle kwebhotile xa ivuza, ibangela iimpazamo zovavanyo, beka ibhotile kwi-stirrer magnetic ukuze ishukumise.Ungabamba intamo yebhotile ngesandla sakho kwaye usebenzise isihlahla sakho.Vuthulula ukudibanisa ngokulinganayo.

2. I-conical flask ingasetyenziselwa kwiimvavanyo eziqhelekileyo ukuvelisa igesi okanye njengesitya sokusabela.Ubume bayo obuyiconical buzinzile

3. Umkhumbi unokufudunyezwa kwindawo yokuhlambela amanzi okanye kwisitofu sombane

Ukulumkela

(1) Ulwelo olutofwayo alugqithi kwi-1/2 yomthamo walo, kwaye kulula ukubangela ukutshiza ukuba lukhulu kakhulu.

(2) Sebenzisa i-asbestos mesh xa ufudumeza (ngaphandle kokufudumala kwesithando sombane).

(3) Umphandle weflaski oyiconical ufanele wosule ngaphambi kokuba ufudunyezwe.

(4) Emva kokusetyenziswa, kufuneka icocwe ngesicoci esikhethekileyo, yomiswe, ize igcinwe kwisitya esomileyo.

(5) Phantsi kweemeko eziqhelekileyo, ayinakusetyenziselwa ukugcina ulwelo.

(6) Jikela kwicala elinye xa ujikeleza

Ndiyeza!

Eyona nto ibalulekileyo nantsi!

ke le lab rhoqo

Ekugqibeleni indlela yokucoca ukuyicoca?

Khawuleza umeme abameli banamhlanje benqanaba eliphezulu:

Iiflaski ze-Erlenmeyer ezingakhange zicocwe kwigumbi lovavanyo lenkampani ngaphezulu kwesiqingatha sonyaka

Okokuqala zama ukuhlamba ngamanzi ashushu + isicoci esiqhelekileyo sokuncedisa

Isiphumo...Andikwazi tu ukuyihlamba...

Okanye umeme umlinganiswa wethu oyintloko- iIlebhu yokucoca iglasi ezenzekelayo!

Sifaka ibhotile ngqo kwiiwasha yeebhotileyokucoca

Emva kwemizuzu engama-40 yokucoca

Iiflaski ze-Erlenmeyer zicacile kwakhona!

Ngaba usenexhalaIwashi yeglasi yeLabhoratringesandla?

Yiza ke uzame iwasha yeebhotile!
