Features
Material:
High{{0}purity fused quartz (99.99% SiO₂) ine ultra-low trace metals.
Thermal Resistance:
Inoshingirira tembiricha inosvika 1,200 degrees (nguva pfupi-yenguva pfupi) uye 1,050 dhigirii (kuenderera mberi kushandiswa).
Optical Properties:
Yakanakisa UV uye IR kutapurirana (∼90% transmittance pa200–2,500 nm).
Kemikari Inertness:
Inopikisa acids (kunze kweHF), halogens, uye organic solvents.
Kuwedzera Kwekupisa Kwepasi:
Coefficient ye 0.55 × 10⁻⁶/ dhigirii, kuve nechokwadi chekuchinja kushoma pasi pekunetseka kwekupisa.
Customizable:
Inowanikwa mumadhayamita akasiyana-siyana (1-200 mm), kureba (kusvika 1,500 mm), uye zvigadziriso (zvakavharwa / zvakavharwa, zvakanatswa magumo).

FAQ
Q: Ndeipi yakanyanya tembiricha iyo quartz yakavharwa pasi chubhu inogona kumira?
A: Inogona kumira kuenderera mberi kwekushanda pa1100 dhigirii uye pfupi - nguva yekuratidzwa kusvika ku1450 degree.
Mubvunzo: Iyo chubhu inopesana neasidhi uye alkalis here?
A: Hongu, inopikisa zvakanyanya kune akawanda acids uye alkalis, asi haifanirwe kushandiswa nehydrofluoric acid, sezvo quartz inopindirana neHF.
Mubvunzo: Iyo yakavharwa yepasi chubhu inogona kuvharirwa here?
A: Ehe, inoenderana ne autoclaving nekuda kwekuita sterilization.
Q: Iyo yakavharwa yepasi chubhu inogona kugadziridzwa maererano nehukuru uye chimiro?
A: Ehe, tinopa masevhisi ekugadzirisa madhayamita, kureba, uye magadzirirwo akakosha kusangana nezvinodiwa zvekushandisa.
Mubvunzo: Ndeipi nguva yekutungamira yemirairo?
A: Izvo zvinoenderana nehuwandu hwekuraira.
