We also have other Quartz Tube As follow:
option-1: Clear Quartz Tube
It’s made from natural quartz after the process of melting and fine grinding. It has high purity, heat resistance and corrosion resistance, also be low coefficient of thermal expansion. It contains no air bubble and controlled to the grade of PPM, has the great performance such as high temperature proof, chemical stability, perfect insulation and transmittance, etc.
option-2: UV Stop Quartz Tube
This cerium-added tube can effectively prevent all radiation of UV-B and UV-C ultraviolet and most radiation of UV-A ultraviolet. Effectively protect human and object from hurt of ultraviolet with best transmission.
option-3: Ozone-free Quartz Tube
The surface is transparent and slight purple of the cut surface. Doped with Ti, it has a strong ability to prevent dense UV radiation but release no ozone. The product blocks wavelength<220nm, while transmit over 70% in 253.7nm.
option-4: Infrared Quartz Tube
It’s doped with trace elements and appears red, dark red and pink colors. It is able to prevent all the UV rays and part of visible lights and meanwhile make the most of infrared rays. It’s used in the field of far infrared heating, such as heater, sterilization tank, oven, drying, etc.
