Laboratory and Chemical ApplicationsA quartz branch tube reactor is a specialized reactor crafted from quartz glass, renowned for its exceptional chemical stability, high mechanical strength, and excellent optical transparency. This type of reactor is designed to facilitate chemical reactions under demanding conditions, such as high temperatures and pressures. Quartz glass is primarily composed of silicon dioxide (SiO2), which provides inherent resistance to corrosion from various strong acids, strong bases, and organic solvents. These reactors find extensive use in diverse fields like chemical analysis, biological research, and environmental monitoring. In chemical analysis, the quartz branch tube reactor acts as a highly sensitive and precise reaction vessel or detection unit, ensuring reliable and repeatable results. In biological research, it is essential for applications like PCR amplification and nucleic acid electrophoresis. For environmental monitoring, it is used to analyze pollutants in air, water, and soil samples. Key advantages include high thermal stability, superior chemical inertness, excellent optical properties (particularly in UV and IR ranges), and robust mechanical strength. However, quartz’s inherent lack of ductility and its fragile nature need to be considered during handling and operation.

Quartz glass provides significant mechanical strength, ensuring stability under high-pressure conditions and making these reactors reliable for high-pressure reaction environments.
Application Scenario
Analytical Chemistry
In analytical chemistry, these reactors are frequently employed as reaction vessels or detection units in techniques like gas chromatography (GC), high-performance liquid chromatography (HPLC), and atomic fluorescence spectroscopy (AFS). They offer high sensitivity, precision, and excellent repeatability for reliable quantitative analysis.
Biotechnology and Life Sciences
In biotechnology and life sciences, quartz branch tube reactors are utilized in experiments such as PCR amplification, nucleic acid electrophoresis, and cell culture. Their ability to withstand high temperatures and pressures, combined with their excellent optical transparency, allows for real-time monitoring of amplification products and cellular processes.
Environmental Analysis
For environmental analysis, these reactors serve as reaction vessels or sampling devices for the determination of pollutants in air, water, and soil samples. Their high sensitivity and accuracy ensure reliable detection and quantification of environmental contaminants.
Chemical Synthesis
Quartz branch tube reactors are also extensively used in chemical synthesis as reaction vessels. Their capacity to withstand high temperature and pressure conditions makes them ideal for a broad range of chemical reactions.
The typical operating temperature range for a quartz branch tube reactor is between -50°C and 1200°C. However, the precise temperature limit is contingent on the purity of the quartz glass and the specific manufacturing processes employed. High-purity quartz glass provides enhanced thermal stability, maintaining its integrity at elevated temperatures. Therefore, it is crucial to select the appropriate quartz glass grade based on your experiment’s temperature requirements and to operate the reactor within its safe operating range to prevent potential material failure or compromised performance due to excessive heat.
Proper cleaning and maintenance of a quartz branch tube reactor are essential for ensuring its optimal performance and longevity. Initially, inspect the reactor for any signs of cracks or damage prior to use. After each use, promptly clean the reactor’s interior with deionized water or a suitable solvent to prevent the build-up of residues and potential corrosion. For persistent stains or difficult to remove deposits, consider using an ultrasonic cleaner or specialized cleaning solutions. Regular inspection of the reactor’s seals and connectors is necessary to ensure they remain intact and leak-free. During storage, keep the reactor in a dry, cool, dust-free environment, shielded from direct sunlight and potential mechanical damage.
When using a quartz branch tube reactor, it is crucial to adhere to the following safety measures: Firstly, always wear appropriate personal protective equipment (PPE), such as gloves, safety goggles, and a lab coat, to protect against exposure to chemical reagents or high temperatures. Secondly, when operating under high-temperature and high-pressure conditions, verify that the reactor’s seals are tight to prevent explosions from overpressure. Additionally, strictly follow established experimental operating procedures, and avoid any sharp vibrations or impacts to prevent breakage of the reactor. Finally, take special care when handling corrosive reagents such as strong acids and strong bases, verifying the reactor’s compatibility and material resistance to chemical corrosion to avoid damage.

Frequently asked questions
Quartz glass is a hard and brittle material with excellent physical and chemical properties, extremely high mechanical hardness, good electrical insulation, high temperature and corrosion resistance, low and stable delay performance, good light transmittance, etc. It is widely used in semiconductors, optics, electricity, chemistry, aerospace, automobiles and other fields. Hard and brittle materials are difficult to process, and many fields urgently need cutting processes with small edge collapse, less material loss, low cross-section roughness, and a wide cutting thickness range. The traditional cutting method of quartz glass is mechanical cutting, that is, wheel cutting. Non-traditional cutting methods include water jet cutting, electrochemical discharge wire cutting, continuous laser cutting, etc. Mechanical cutting has low cost, but the contact between the wheel and the material causes large tool wear, and the material is easily contaminated by the tool. Quartz glass is prone to edge collapse, microcracks, and residual stress, which affects the strength and performance of the material! It is difficult to achieve curve cutting and requires post-processing, such as grinding and polishing. Laser cutting does not directly contact the material, has no contact stress, and can perform complex curve cutting. Picosecond laser has the advantages of small spot diameter, high precision, short action time with the material, and small action area, and is suitable for the processing of hard and brittle materials.
