Application
Volumetric flasks are precision glassware used for:
- Accurate preparation of standard solutions
- Dilution to an exact known volume
- Analytical chemistry, dairy, petroleum, pharmaceutical, and educational laboratories
- Calibration and quantitative analysis work
Compliance Standard
- ISO 1042 – Laboratory glassware, volumetric flasks
- ASTM E288 – Standard specification for volumetric flasks
- DIN EN ISO standards for Borosilicate Glass 3.3
- Class A / Class B accuracy as per standards
Product Description
Volumetric flasks are manufactured from high-quality, low expansion Borosilicate Glass 3.3. They have a pear-shaped body with a long narrow neck and a single calibration mark etched on the neck for precise volume measurement.
Each flask is supplied with a well-fitting interchangeable stopper (glass or plastic). Clear graduation line and markings are printed in permanent enamel. Designed for high accuracy in solution preparation and dilution.
