REILGLAS Volumetric Flasks – Class ‘A’ are high-precision laboratory glassware designed for accurate preparation, dilution, and storage of standard solutions. Manufactured from high-quality, chemically resistant glass, these flasks provide excellent transparency, thermal stability, and long-term dimensional accuracy.

Each flask is supplied with a precision interchangeable glass stopper, providing a secure, leak-free seal and minimizing evaporation or contamination during use. The flasks are calibrated to contain (TC) a specified volume at 20°C, with a single permanent calibration mark on the neck for precise volume setting.

Conforming to Class ‘A’ accuracy requirements, these volumetric flasks offer tight tolerance limits and high repeatability. Clear, permanent calibration markings ensure excellent readability and reduced parallax error.

Special design notes:

• 1 ml & 2 ml flasks are supplied in test tube shape

• Stopper sizes are matched to capacity for proper sealing and handling

Available capacities range from 1 ml to 5000 ml, making these flasks suitable for:
