Borosilicate Glass Tubes

Factory-direct borosilicate glass tubes for chemical, pharmaceutical, laboratory, and industrial process applications. Available in standard and custom dimensions — specify your outer diameter (OD), inner diameter (ID), wall thickness, and length. OEM and bulk orders welcome.

Key Properties

  • Thermal shock resistance — withstands rapid temperature changes from -40°C to +250°C without cracking
  • Low thermal expansion — coefficient ~3.3 × 10⁻⁶/K, approximately 3× lower than ordinary glass
  • High chemical resistance — resistant to most acids, alkalis, and solvents
  • Optical clarity — high light transmission for visual inspection applications
  • Non-porous surface — prevents contamination, easy to clean

Typical Applications

  • Chemical and petrochemical processing — reactor tubing, pipeline observation
  • Pharmaceutical manufacturing — sterile process tubing, inspection windows
  • Laboratory equipment — condensers, reaction vessels, flow cells
  • Food and beverage — hygienic flow observation, level monitoring
  • Semiconductor and electronics — diffusion furnace tubes, process chambers

Custom Specifications Available

We manufacture to your exact requirements. Common parameters include:

  • Outer diameter (OD): 5mm – 300mm
  • Wall thickness: 1mm – 20mm
  • Length: up to 2000mm (custom cuts available)
