Complete Specifications
The Tube Furnace Quartz Sample Holder is a common accessory in laboratory processes, designed to carry and support samples within the furnace tube.This holder is crafted from high-purity quartz glass, boasting a 99.99% silicon dioxide (SiO2) content. Featuring double-sided welding for enhanced structural strength and undergoing annealing and dehydroxylation for stress relief, it offers an extended lifespan. Its excellent thermal shock resistance allows it to reliably withstand working temperatures up to 1200°C without deformation or melting. It is less prone to cracking during sudden temperature changes and maintains structural stability throughout heating and cooling cycles.
Available in various sizes to fit your specific furnace dimensions, the high purity material ensures prevention of sample contamination. Simultaneously, it protects the furnace chamber and the expensive furnace tube bottom by preventing corrosive substances or molten materials from direct contact and damage. This quartz sample support is an essential tube furnace accessory for clean and stable high-temperature experiments.
