Laboratory and Chemical Applications
Our high-purity quartz chambers for muffle furnaces are engineered to provide unparalleled protection against corrosive gases and extreme temperatures. Crafted from 99.99% pure fused silica, these robust liners safely operate up to ~1200°C and are highly resistant to acids, including hydrogen fluoride (HF) gas, which commonly damages standard furnace insulation and heating elements. By installing a custom-fitted quartz chamber, you can significantly extend your furnace’s lifespan, maintain high sample purity, and simplify cleaning in demanding laboratory and industrial processes.

High Temperature Resistance
Designed to operate effectively at temperatures up to ~1200°C, the quartz chamber maintains structural integrity and performance even under extreme thermal conditions, making it suitable for a wide range of high-temperature material processing applications.
Prevents Contamination & Ensures Purity
The high purity (99.99% SiO2) and chemical inertness of quartz ensure that the chamber itself does not introduce impurities into the processed materials. This is critical for applications requiring ultra-clean environments or the treatment of sensitive compounds.
Easy to Clean & Maintain
Unlike porous ceramic furnace linings, the smooth, non-porous surface of the quartz chamber is resistant to material adhesion and is remarkably easy to clean. This simplifies maintenance, reduces downtime, and helps maintain a consistently pure processing environment.
Exceptional Corrosion Protection (Especially HF)
Crafted from high-purity quartz, this chamber provides unparalleled resistance to highly corrosive gases, including hydrogen fluoride (HF) and various acids. This protects the core furnace components like heating elements and insulation from degradation, significantly extending the furnace’s operational life.
Application Scenario
Processing of Fluorine-Containing Materials
Essential for muffle furnaces used in the thermal treatment, ashing, or decomposition of fluoropolymers and other materials that release hydrogen fluoride (HF) gas, which is highly corrosive to standard ceramic furnace linings and heating elements.
Acid Digestion and High-Purity Sample Preparation
Utilized when samples are digested or incinerated in an acidic atmosphere, ensuring the furnace chamber itself does not react with the corrosive fumes or introduce impurities, which is critical for accurate analytical results.
Materials Science Research & Development
Employed in R&D labs for synthesizing or treating novel materials under high temperatures where corrosive byproducts are generated, or where maintaining an ultra-clean, non-reactive furnace environment is crucial for experimental integrity.
Industrial Heat Treatment in Corrosive Environments
Applied in industrial settings where continuous high-temperature operations expose furnaces to corrosive gases from the materials being processed, significantly extending the lifespan of expensive muffle furnaces and reducing maintenance costs.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
Our quartz chambers are primarily custom-designed to perfectly fit your specific muffle furnace model and internal dimensions. While we offer common configurations, precise measurements are taken to ensure optimal integration and protection for your existing heating elements and insulation. Please provide your furnace details for a tailored solution.
A quartz chamber can dramatically extend the lifespan of your muffle furnace, often by several times, particularly in applications involving corrosive gases like HF. It acts as a sacrificial barrier, protecting the expensive heating elements and insulation materials that would otherwise quickly degrade, saving significant replacement and maintenance costs.
No, quite the opposite. One of the key advantages of quartz is its smooth, non-porous surface, which is highly resistant to material adhesion. This makes the quartz chamber exceptionally easy to clean compared to traditional porous ceramic linings, allowing for quick residue removal and maintaining a high-purity environment with minimal effort.
