Inquiry (采购产品): Borosilicate glass bead Hi I would like to get more information about your product, the borosilicate glass bead. Is your glass 'Type I glass, low-expansion borosilicate glass'? What is the smallest size of the bead you can make? Can they go as low as several hundred microns in diameter? Thank you. **** Hidden Message ***** IRIS HUANG 91360 Company: AMGEN E-mail: yuh@amgen.com **** Hidden Message ***** yuh@amgen.com
