Fused Quartz Fabrication

At QSI we are the experts at finding better ways to design state-of-the-art fused quartz fabrication products of every shape and size. These quartz glass fabrications are made to meet the diverse laboratory and process needs of our customers around the globe. Many of our production processes involve the use of proprietary equipment engineered to our specifications to provide fused quartz fabrications and lab ware of the highest purity and strength.

QSI fused quartz fabrications’ purity levels (99.998% SiO2) are attained by careful screening of raw material, meticulous attention to detail, and stringent quality control throughout the various manufacturing stages. QSI stocks and supplies quartz glass in a variety of forms such as tubing, rods, ingots, plates, discs, and cylinders. From thin-wall boiling and distilling flasks to heavy-wall diffusion tubes used to process semiconductor wafers at furnace temperatures in excess of 1200 degrees C. QSI offers custom fused quartz fabrications and other products to customer specification and configuration. As well, QSI can make repairs of fused quartz glass fabrications when feasible.

QSI fused quartz fabrication products meet or exceed all industry standards for physical, thermal, chemical, mechanical and electric properties.

Quartz Scientific, which offers the flexibility and service typically associated with smaller firms, offers custom quartz fabrication, a process in which quartz is heated in a glass-blowing lathe with a hydrogen-oxygen flame until it is plasticized and can be formed into any shape. A thermodynamic process, it can be used for lamp bodies, resizing, manifolding, repair, prototype shapes, diameters, and lengths. It works well for a variety of shapes up to 32” in diameter and up to 10’ long. Purity is 99.99+% with a thin or heavy wall. Typical products include crucibles, process tubes, bell jars, cylinders, furnace tubes, beakers, dishes and related products for the laboratory, semi-conductor, solar silicon, university research and medical sectors. Quartz Scientific can handle small to large-volume production runs and offers 100% inspection, product characterization and ISO 9002 certification. Lead time is the best in the industry.
