Description

1. Materials: Quartz glass tube (silica content≥*9.*9%) 2. For cutting quartz tube, our company develop advanced equipment to cut, clean, package, etc. As the first-class technology, we use import diamond cutting disc and ultrasonic cleaning equipment to ensure that every specification of the consistency of a product from the aspect smooth, flat, the appearance of cleanliness, well controlled dimension and low OH etc., 3.They’re widely used in the prodcucts such as halogen lamps, mercury lamps, metal halide lamps, as well as in the field of sample collection and semiconductor.
