FAQs
Can this conical flask be used for high-temperature sterilization?
Yes, the Xin Tester Conical Flask is made of GG-17 high borosilicate glass, which is highly resistant to heat. It is suitable for high-temperature sterilization and autoclaving procedures commonly required in microbiology and chemistry labs.
What are the benefits of the hollow glass stopper?
The hollow glass stopper provides an excellent airtight seal to prevent the evaporation of volatile substances. Its hollow design makes it easier to handle and reduces the overall weight while maintaining a precision-ground fit that ensures no leaks during reflux or distillation.
Is the graduation scale accurate enough for measuring?
The printed graduations on the Xin Tester Erlenmeyer flask are clear and designed for approximate volume measurement. While ideal for general lab work and mixing, we recommend using a graduated cylinder or pipette for applications requiring high-precision volumetric measurement.
Is the flask resistant to chemical corrosion?
Absolutely. Boro 3.3 (GG-17) glass is chemically inert and offers superior resistance to most acids, alkalis, and organic solvents, ensuring that your reagents remain uncontaminated and the glass does not degrade over time.
