FAQs
What makes this beaker suitable for routine laboratory use?
This 250 ml low-form borosilicate beaker is designed for consistent day-to-day lab work where reliability and repeatability matter. Its heavy, uniform wall thickness improves durability during frequent handling, while the beaded rim and stable low-form design reduce the risk of chipping or tipping. Combined with clear graduations, it supports accurate measurement across a wide range of basic lab applications.
How accurate are the volume markings on this beaker?
The beaker features a double graduated metric scale with an approximate tolerance of ±5%, which is standard for general-purpose laboratory beakers. While it is not intended for high-precision analytical measurements, it is well-suited for approximate volume estimation, solution preparation, and mixing tasks where exact volumetric accuracy is not critical.
Can this beaker safely handle heating and cooling cycles?
Yes, the low-expansion borosilicate glass is specifically chosen for its ability to withstand thermal stress better than standard glass. It can handle typical laboratory heating applications, including use on hot plates. However, it should not be exposed to sudden temperature changes, such as moving directly from a hot surface to cold water, as extreme thermal shock can still cause cracking.
What advantages does borosilicate glass offer over regular glass?
Borosilicate glass provides significantly higher resistance to thermal expansion and chemical corrosion compared to standard soda-lime glass. This means it is less likely to crack under temperature changes and is more resistant to acids and alkalis commonly used in laboratory environments. As a result, it improves both safety and product lifespan in demanding lab conditions.
Is this beaker suitable for chemical storage or only for mixing?
While the beaker can temporarily hold and mix a wide range of chemicals due to its chemical resistance, it is not designed for long-term storage. Beakers have an open-top design, which makes them unsuitable for preventing evaporation, contamination, or exposure over extended periods. For storage applications, sealed laboratory bottles or flasks are recommended.
