Being a manufacturer, we focus on providing custom fused quartz tubes for tube furnaces. We select the optimal size based on your requirements and utilize processes like precision cutting, flame sealing, and finishing to create tubes that fit your exact specifications.
Marked as 50od44id600l mm
- The vacuum pressure can only be safely used below 1200°C.
- The gas flow rate should be limited to <200 SCCM (or 200 ml/min) to reduce thermal shock to the tube.
- The quartz tube is designed for use under vacuum and low pressure at 0.2 bar / 3 psi / 0.02 MPa.
If samples need to be placed, quartz glass semi-cylindrical boats, tubular furnace wafer boats, or quartz crucibles can be used to hold the samples, which can extend the service life of the quartz tube and facilitate cleaning and maintenance.
When receiving the package, ensure that it is intact. To ensure transportation safety, we use bubble wrap + export wooden crates for shipping. We can provide bulk pricing for distributors.
