Sight glasses made of fused quartz glass
As a sight glass Quartz glass has many positive properties such as high temperature resistance, good thermal shock resistance, low coefficient of thermal expansion and high purity.
|Shape||Square, round, oval, triangle, other customized shapes|
|Clear aperture||>85%, >90% >95%|
Factors affecting price
As a manufacturer with rich processing experience, we will think from the perspective of customers and strive to provide suitable products.
Maybe our price is not the best, but our products must be your safe choice.
The following will have an impact on the quotation.
Raw materials: Quartz glass is divided into ultraviolet quartz (JGS1), far ultraviolet quartz (JGS2) and infrared quartz (JGS3). Choose the appropriate material according to your requirements.
Dimensions: the size of the external dimensions, thickness, surface accuracy, parallelism, these information are determined according to the purpose you use, The higher the accuracy requirement, the more expensive the price.
Quantity: The price of 2 pieces and 50 pieces, 500 pieces and 1000 pieces are different.
The complexity of the production, whether it is coated or not, the air line transmittance requirements of bubbles, and other special needs of customers will also affect the price
