End close Quartz Tube

The End close Quartz Tube  features a precision-sealed bottom designed for protective housing and immersion applications. It provides a leak-proof, high-purity barrier for sensors and heating elements in extreme environments.

Ideal for thermocouple protection, liquid immersion heating, and vacuum-sealed laboratory experiments.

• Secure Seal – Precision-fused closed end for airtight/watertight protection
• Extreme Heat – Continuous operation up to 2012°F (1100°C)
• High Purity – ≥99.9% SiO2 ensures zero process contamination
• Thermal Shock Stable – Withstands rapid temperature changes without cracking
• Precision Geometry – Uniform wall thickness for consistent thermal conductivity
• Chemical Proof – Highly resistant to acids and corrosive immersion fluids

Fully compatible with: Thermocouple sensors, immersion heaters, chemical reaction vessels, and atmospheric furnace testing.
