User asked:

Our high-temperature experiments always encounter problems such as material deformation and inaccurate data. Is there a more stable reaction vessel

Our answer: High purity quartz tubes can withstand sustained high temperatures above 1200 ℃, with an extremely low coefficient of thermal expansion, ensuring a stable experimental environment.

User asked:

It is necessary to observe the chemical reaction process, but ordinary glass is prone to fogging, which affects monitoring accuracy

Our answer: The quartz tube has a transmittance of over 90% and maintains excellent transparency in both ultraviolet and infrared bands, supporting high-definition observation throughout the entire process.

User asked:

The experiment involves a strong acid or plasma environment, and the container wears out too quickly

Our answer: Quartz material has excellent corrosion resistance and can resist most acids, gases, and high-frequency plasma erosion, increasing its service life by 3-5 times.

In the precise and demanding field of scientific research, the selection of every experimental component is crucial, as it directly affects the accuracy of data, the reproducibility of experiments, and the safety of personnel and equipment. Among numerous materials, quartz glass tubes (hereinafter referred to as "quartz tubes") have become the "standard configuration" in many cutting-edge research laboratories due to their unique physical and chemical properties. As a foreign trade manufacturer specializing in high-end customized quartz products, we will objectively and clearly explain from a professional perspective why quartz tubes are the ideal choice for scientific research institutions.

The excellent product advantages of quartz tubes: not just high temperature resistance

Quartz tube is a special industrial technical glass made of high-purity silicon dioxide (SiO ₂). Its core advantage stems from its unique amorphous structure:

1. Extremely high thermal stability: The softening point of quartz tube is as high as 1730 ℃, and it can work stably for a long time at 1200 ℃, with an instantaneous temperature difference of over 1000 ℃. This makes it the preferred choice for high-temperature reactions such as CVD chemical vapor deposition, semiconductor diffusion, and material sintering.

2. Excellent optical performance: Quartz tubes have extremely high transmittance for ultraviolet, visible, and near-infrared light (up to 93%). This is crucial for applications such as optical experiments, UV curing, and spectroscopic analysis.

3. Excellent chemical inertness: Except for hydrofluoric acid and hot phosphoric acid, quartz tubes hardly react with other acidic substances and have better resistance to alkalinity than the vast majority of glass and metals. This ensures the purity of the experiment in a highly corrosive chemical environment.

4. Extremely low thermal expansion coefficient: The thermal expansion coefficient of quartz tubes is extremely small (about 5.5 × 10 ⁻⁷/℃), which means that their shape and size remain almost unchanged under rapid temperature changes, and they have excellent thermal shock resistance, effectively avoiding rupture caused by thermal stress.

5. High purity and electrical insulation: Our products such as "transparent quartz tubes" and "milky white quartz tubes" have a purity of over 99.99%, avoiding metal ion contamination. They are also excellent electrical insulators suitable for high-purity experiments and high-voltage environments.

What key scientific research problems can quartz tubes solve?

In the laboratory, inappropriate materials can introduce a series of variables and risks. The application of quartz tubes aims to accurately address these pain points:

Addressing pollution issues: High purity ensures that experimental samples (such as semiconductor wafers, high-purity metals, specialty chemicals) are not contaminated by containers during production or analysis.

Breaking the temperature limit: When the experimental temperature exceeds the tolerance range of ordinary glass or metal, the quartz tube provides a stable and reliable high-temperature environment.

Ensuring the accuracy of optical experiments: In applications that require precise optical paths or ultraviolet light sources, the absorption and scattering of light by ordinary materials can introduce errors, while the high transparency of quartz tubes ensures the integrity of optical signals.

Enhance safety and durability: Excellent thermal shock resistance and chemical stability reduce the risk of experimental failure, equipment damage, and even personal injury caused by container rupture, extending the service life of consumables.

Core application scenario: The specific manifestation of quartz tubes in scientific research

Semiconductor and Microelectronics Research: Furnace Tubes for Diffusion, Oxidation, and CVD Processes of Wafers.

Research on Chemical Synthesis and Catalysis: As a reaction tube, observation window, or core component of photocatalytic reactors for high-temperature and high-pressure reactions.

Materials Science: Used for the synthesis and heat treatment of new materials such as graphene and nanomaterials.

Analytical instruments: used as atomizers and combustion tubes in instruments such as atomic absorption spectroscopy (AAS) and inductively coupled plasma (ICP).

Light source industry: Manufacturing casings for high-intensity light sources such as xenon lamps and ultraviolet lamps.

Real case (anonymous)

Case 1 (Chemistry Department of a European university): The laboratory needs to conduct a new catalyst synthesis experiment at 1250 ℃ in a fluorine-containing atmosphere. The heat-resistant glass tubes they used before frequently experienced deformation and loss of transparency. We customized a quartz tube with a specific thickness to resist hydrogen fluoride corrosion, successfully solving the problem and allowing the experiment to run continuously and stably for more than 6 months. The customer highly appreciates the durability of the product.

Case 2 (a photovoltaic research institute in North America): The customer requires a quartz reaction chamber with precision side branches and observation windows for CVD deposition of thin film solar cell materials. Our engineering team has closely communicated with them and successfully manufactured an integrated quartz cavity that fully conforms to their complex design, ensuring the uniformity of airflow and visualization of experiments, helping customers improve research and development efficiency.
