Tall Form Graduated Glass Beaker (Berzelius)

The Tall Form Graduated Glass Beaker (Berzelius) is laboratory glassware used for holding, mixing, dissolving, and heating liquids in analytical and preparative procedures. The tall Berzelius form provides increased height relative to the base diameter, helping reduce splashing during heating and stirring. It features approximate graduation markings intended for volume estimation only and does not replace calibrated volumetric glassware. It is widely used in general laboratory routines such as solution preparation, controlled heating, and liquid transfer.

FAQ

Q: Can the graduation be used for precise volume measurements?
A: No. The graduation is for reference only and does not replace calibrated volumetric glassware.

Q: Can this beaker be heated directly?
A: Yes. Borosilicate glass allows heating when performed gradually and without thermal shock.

Q: What is the difference between tall form and low form beakers?
A: Tall form beakers have greater height relative to base diameter, which helps reduce splashing during heating and handling larger volumes.

Q: Is it suitable for use with a magnetic stirrer?
A: Yes. The flat bottom allows use with magnetic stirrers under appropriate operating conditions.
