Iro Borosilrate Girazi rakagadzirwa muChina rakachengeteka here?

Borosilrate girazi racho rinotungamira uye cadmium-emahara, uye hazvizozombove nemakemikari anokuvadza mune yako tii . Icho chinhu chepamusoro chinoshandiswa tsika yesainzi uye vashandi vekuramusha uye kunyange kurwisa kwemakemikari uye kwakasimba zvakakwana kuti ukure marara enyukireya.

Test tubes yakagadzirirwa yebasa rekereke yakajairika inowanzogadzirwa negirazi , yekupikisa kwaro kupisa. Mabhonzo akagadzirwa kubva pakuwedzera-anodzivirira magirazi, kazhinji borosilrate girazi kana yakasimba Quart

Girazi test tubes zvakakwenenzverwa uye kupisa uye / kana makemikari anoramba . Ivo vari nyore kuona kuburikidza nemapurasitiki emapurasitiki. Borosilicate glass test tubes can withstand thermal shock and chemical shock which makes them a common test tubes material for chemistry applications.

Yakagadzirwa kubva kuBoorosilrate Girazi nehurema hwekuremekedza madziro ekuramba kwakasimba kupisa uye makemikari. Hoffherbrand
