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.
