Our glass burette is crafted from high-grade borosilicate glass, offering excellent chemical resistance and clarity. Designed for precise liquid dispensing in titration, it features clear, laser-engraved graduations and a reliable stopcock for controlled flow. Available in Class A and Class B with common volumes of 10ml, 25ml, and 50ml, it meets international laboratory standards. Widely used in chemical analysis, pharmaceutical testing, and educational labs, it ensures accurate volume measurement for reliable experimental results.
1. Our laboratory glass burette is made of high-purity borosilicate glass, withstanding temperatures from -20℃ to 150℃ and resisting most corrosive reagents. Each unit undergoes strict calibration, ensuring long-term stability in chemical analysis and quality control environments.
2. The volumetric glass burette features laser-engraved graduations with a precision error as low as ±0.02ml for Class A models. Clear, fade-resistant markings enable accurate volume reading at eye level, making it ideal for quantitative titration in pharmaceutical and environmental testing.
3. Our glass burette with stopcock includes a precision-ground glass valve for smooth, leak-proof flow control. The tightly fitted stopcock eliminates reagent leakage, supporting consistent drop-by-drop delivery in sensitive analytical procedures across research and teaching labs.
4. The glass burette with PTFE stopcock offers superior chemical inertness and effortless operation, free from jamming or seizing. It is compatible with strong acids, alkalis, and organic solvents, enhancing safety and service life in heavy-use laboratory workflows.
5. Available in 10ml, 25ml, and 50ml standard volumes, our laboratory glass burette conforms to ISO 385 international standards. With a 99.8% factory inspection pass rate, this volumetric glass burette delivers reliable performance for routine and high-precision analytical applications.
6. The uniform wall thickness and reinforced top structure reduce breakage risk, while the smooth inner surface minimizes liquid retention. Our glass burette with PTFE stopcock is easy to clean and reusable, lowering operational costs for long-term laboratory use.
1. Our laboratory glass burette is widely used in quantitative chemical analysis, delivering precise titrant volumes for acid-base, redox, and complexometric titrations in research and industrial quality control labs.
2. The volumetric glass burette ensures accurate measurement in pharmaceutical labs, supporting assay testing of active pharmaceutical ingredients and compliance with strict drug quality standards.
3. Glass burette with PTFE stopcock excels in environmental testing, safely handling corrosive reagents for water/soil sample analysis, such as detecting heavy metals and organic pollutants.
4. In educational laboratories, this glass burette with stopcock is essential for teaching titration techniques, helping students master quantitative analysis principles and experimental operation skills.
5. Food safety testing relies on our glass burette to determine additives, preservatives, and nutrient content, ensuring food products meet national and international safety regulations.
Rinse the glass burette with titrant first, then fill it above the zero mark and release liquid to remove air bubbles. Adjust the meniscus to zero, control the stopcock smoothly for dropwise titration, and read the final volume at eye level for accurate results.
