• Kev tsim kho ruaj khov thiab txhim khu kev qha

  Yuav kom tiv taus qhov chaw ua haujlwm hnyav, peb cov tsom iav pom kev muaj lub thav hlau ruaj khov, feem ntau yog ua los ntawm cov hlau tsis xeb lossis cov khoom sib xyaw uas tiv taus xeb. Lawv tuaj yeem tiv taus kev kub siab, kub heev thiab cov tshuaj lom neeg kom muab kev pabcuam ntev thiab tsis muaj teeb meem.

• 

• Ib daim ntawv thov dav dav

  Cov tsom iav no siv dav hauv ntau yam lag luam. Hauv kev lag luam khoom noj thiab dej haus, lawv pab tswj cov qauv kev huv los ntawm kev tso cai rau kev tshuaj xyuas cov txheej txheem khoom. Hauv kev lag luam tshuaj lom neeg, lawv yog qhov tseem ceeb rau kev saib xyuas cov tshuaj lom neeg thiab kev hloov pauv ntawm cov tshuaj phom sij. Hauv kev lag luam tshuaj, lawv ua kom zoo thiab kev ncaj ncees ntawm cov txheej txheem tsim tshuaj.

• Yooj yim rau nruab thiab tswj

  Tsim los kom yooj yim rau cov neeg siv, peb cov tsom iav pom yeeb nkab yooj yim rau kev teeb tsa. Lawv tuaj nrog cov khoom siv sib txuas thiab tuaj yeem sib xyaw ua ke tau yooj yim rau hauv cov kav dej uas twb muaj lawm. Kev saib xyuas kuj yooj yim heev, nrog rau cov iav uas yooj yim ntxuav thiab cov khoom hloov tau.

Cov txheej txheem tsis qhia

Peb cov tsom iav pom kev yog ua los ntawm cov iav borosilicate zoo lossis iav tempered. Lub iav pom kev kav dej yog lub cuab yeej saib pom tseeb uas tau teeb tsa rau ntawm cov kav dej kev lag luam. Nws saib xyuas qhov xwm txheej ntws, xim, turbidity thiab lwm yam ntawm cov khoom nruab nrab (kua, roj, pa) hauv lub sijhawm tiag tiag los ntawm lub qhov rais iav saib. Nws yog ib qho khoom siv tseem ceeb los xyuas kom muaj kev nyab xeeb ntawm kev tsim khoom. Nws cov haujlwm tseem ceeb suav nrog: kev saib xyuas ntws (txiav txim siab seb cov khoom nruab nrab ntws lossis txhaws); Kev ceeb toom ua ntej kev nyab xeeb (nres lub tshuab raws sijhawm rau kev saib xyuas thaum pom qhov tsis zoo) Kev txhim kho cov txheej txheem (kho cov kev cai tsim khoom los ntawm kev saib xyuas qhov xwm txheej ntawm cov khoom nruab nrab.
