Unparalleled High-Temperature & Chemical Inertness
Crafted from high-purity fused silica, these holders exhibit exceptional stability at extreme temperatures (common in annealing and sintering) and are highly resistant to most corrosive chemicals, ensuring sample integrity and prolonged service life.
Superior Purity for Contamination-Sensitive Work
The ultra-high purity of the quartz material (SiO2 ≥ 99.99%) guarantees that no impurities are introduced to your sensitive samples during high-temperature treatments, making them ideal for materials science, semiconductor, and other high-precision applications.
High-Throughput Batch Processing
Designed with multiple cavities (4 or 8 standard, customizable) and an extended handle, these quartz sample stages enable efficient simultaneous processing of numerous samples, significantly boosting productivity in laboratory and industrial furnace operations.
Customizable Design & Safe Handling
Beyond standard cavity configurations, these sample stages can be fully customized in terms of cavity size, quantity, and overall dimensions to fit specific furnace types or unique sample requirements. The integrated long handle also ensures safe and easy insertion and retrieval from hot environments.
Application Scenario
High-Temperature Annealing & Sintering of Multiple Samples
Ideal for simultaneous heat treatment, annealing, or sintering of numerous small material samples (e.g., ceramics, metals, nanomaterials) in a single furnace run, optimizing efficiency in materials research and development.
Batch Drying or Calcination in Furnaces/Ovens
Used to dry or calcine multiple powder or solid samples at elevated temperatures, particularly when high purity and a non-contaminating environment are critical for the subsequent analysis or synthesis steps.
Catalyst Screening & Testing
Enables the parallel testing of multiple catalyst formulations under identical high-temperature reaction conditions, allowing researchers to efficiently screen and evaluate the performance of different catalysts.
Gravimetric Analysis & Ashing of Multiple Samples
Provides a high-purity, stable platform for the gravimetric analysis of multiple samples, where precise weighing after high-temperature ashing or ignition in a furnace is required for accurate compositional determination.
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.
The cavities are designed to hold various small samples directly or, more commonly, to accommodate standard or custom small crucibles (e.g., quartz, alumina, platinum crucibles) containing powders, liquids, or solid materials. The precise dimensions of the cavities are crucial, so it’s important to match them with your specific sample vessels. (Note: Crucibles are not included with the sample stage).
The extended handle allows for safe insertion and retrieval of the sample stage into and out of hot furnaces or ovens, keeping the operator’s hands away from high temperatures. Yes, the handle length can be fully customized based on the depth of your furnace, ensuring both safety and convenience for your specific equipment setup.
Yes, being made from high-purity fused silica, this quartz sample stage is highly suitable for use in vacuum furnaces and those operating under inert or controlled atmospheres. Its inertness prevents contamination of the process environment, making it ideal for sensitive applications in materials science and semiconductor processing where atmosphere control is critical.
