FAQs

Q1:Can I heat the Xin Tester Conical Flask directly on a flame?

A1:Yes. We use high borosilicate 3.3 glass for these flasks. This material withstands high temperatures and thermal shock. However, you should heat the flask gradually to ensure even temperature distribution across the base.

Q2:What is the benefit of the flared rim?

A2:The flared rim design allows for easier pouring. It creates a smooth liquid stream and reduces splashing. Furthermore, it provides a better grip when you are handling the flask with laboratory gloves.

Q3:Are the graduations accurate for precise measurement?

A3:The graduations provide a reliable guide for approximate volume. They are clear, wear-resistant, and easy to read. For tasks requiring high-precision volumetric accuracy, we recommend using a calibrated burette or pipette in combination with the flask.

Q4:Is this flask resistant to corrosive acids?

A4:Absolutely. The borosilicate glass provides excellent chemical stability. It resists corrosion from most acids, alkalis, and organic solvents. Consequently, your reagents remain pure during long-term storage or complex reactions.
