High-Temperature Resistance
Quartz tubes can withstand temperatures up to 1250°C without deformation or cracking.
Corrosion
Resistance
These tubes demonstrate exceptional resistance to acids, alkalis, and other corrosive substances.
High Light
Transmittance
Quartz glass provides excellent light transmission across ultraviolet to infrared spectra.
Low Thermal Expansion Coefficient
The minimal thermal expansion coefficient ensures dimensional stability under significant temperature changes.
Application Scenario
Regular Inspection
Periodically inspect the tubes for cracks, deformation, or blockages. Address any issues promptly.
Timely Replacement
Over time, wear, oxidation, or aging can degrade performance. Replace quartz capillary tubes promptly when they no longer meet experimental requirements.
Prompt Cleaning
Immediately after experiments, thoroughly clean the instruments to remove residual samples and solvents. Clean the capillary tubes using solutions like purified water, nitric acid, or ethanol, followed by a final rinse with purified water and thorough drying.
Careful Storage
Store cleaned quartz capillary tubes in a dry, dust-free environment, away from high temperatures and humidity to prevent moisture absorption, deformation, or aging. It’s recommended to disconnect the tubes from connectors and store them in protective packaging like plastic bags.
The service life of a quartz capillary tube is influenced by various factors, including frequency of use, chemical environment, cleaning, and maintenance. With proper use and care, they can last a long time, but it’s hard to generalize a specific duration.
Quartz capillary tubes should be stored in a dry, clean environment, away from direct sunlight and high temperatures to prevent material degradation.
Yes, quartz capillary tubes are suitable for high-pressure applications due to their high mechanical strength and temperature resistance, such as in liquid chromatography.
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.
