A must-have for the laboratory! Guide to purchasing high borosilicate glassware

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.
