Khoom siv: High borosilicate iav (kub kub tiv taus ntawm -30℃txog 400 degree) los yog txheem dej qab zib-txiv qaub iav.
Puab: Cylindrical nrog lub tiaj tiaj hauv qab lossis conical hauv qab; qhov qhib kawg yog feem ntau rimmed.
Dimensions: Txoj kab uas hla 10-25 mm, ntev 75-200 mm, phab ntsa thickness 0.5–1.5 mm.
Yam ntxwv: Pob tshab thiab corrosion-resistant; qee cov hlab ntsha muaj cov qhab nia kawm tiav.
Rau kev saib xyuas niaj hnub, cov iav ntsuas cov raj yuav tsum tau yaug tam sim nrog dej huv tom qab siv. Cov stains tawv tawv tuaj yeem raug tshem tawm los ntawm kev ntub dej hauv cov kua qaub los yog cov tshuaj hauv paus (kev xav hauv qab 10%); tsis txhob siv cov txhuam hniav hlau los tiv thaiv khawb. Periodic sib sib zog nqus tu siv lub tshuab nqus tsev ultrasonic yog pom zoo. Rau kev ua kom tsis muaj menyuam, autoclaving ntawm 121℃rau 20 feeb yog qhov tsim nyog.
