In daily laboratory work, high borosilicate glassware has become an indispensable experimental equipment for researchers due to its excellent temperature resistance and chemical stability. As laboratory equipment experts, we have compiled the following selection points to help you choose the most suitable high borosilicate glass products.
1、 Understand the advantages of high borosilicate glass
Temperature resistance: able to withstand sudden temperature changes from -30 ℃ to 400 ℃
Chemical inertness: Strong corrosion resistance to acidic and alkaline solutions
Low expansion coefficient: The thermal expansion coefficient is only 3.3 × 10 ⁻⁶/℃, ensuring dimensional stability during temperature changes
2、 Select key indicators
Material certification:
Confirm compliance with ISO 3585 international standard
Check the boron silicon content (high-quality products with SiO ₂ ≥ 80%, B ₂ O3 ≥ 12%)
Process standards:
Check the uniformity of vessel wall thickness
Observe whether the seams are smooth and flawless
Confirm that the scale lines are clear and accurate
Common category selection:
Beakers/conical bottles: choose mouth strengthening design
Measuring cylinder/burette: prioritize purchasing white graduated products
Condenser tube: Pay attention to interface standards (24/29, etc.)
3、 Use scenario matching
Conventional experiment: Choose the basic model to meet the needs
High temperature reaction: It is recommended to choose thicker products
Precision experiment: Choose high-precision calibration vessels
Teaching purpose: Consider economical sets
4、 Brand selection suggestions
Prioritize choosing brands that have passed ISO9001 certification
Compare the warranty periods of products from different brands
Understand whether the after-sales service system is complete
5、 Key points of use and maintenance
Avoid sudden cooling and heating, and control the temperature difference within 5 ℃/min
Use specialized brushes during cleaning to prevent scratches
Pay attention to separating and placing during storage to prevent collisions
Special reminder: Please request a material testing report and keep the purchase receipt when making a purchase. We suggest that the laboratory maintain an appropriate amount of spare vessels based on actual usage frequency to ensure uninterrupted experimental work.
Choosing high-quality high borosilicate glassware can not only improve the accuracy of experimental data, but also ensure the safety of experimental personnel. For more professional purchasing advice, please feel free to consult our technical consultant team.
