REILGLAS Volumetric Flasks are high-accuracy laboratory glassware designed for the precise preparation, dilution, and storage of standard solutions. Manufactured from high-quality, chemically resistant glass, these flasks provide excellent thermal stability and long-term dimensional accuracy.

Each flask is supplied with a precision interchangeable glass stopper, ensuring a tight, leak-free seal and minimizing evaporation or contamination. The flasks are calibrated to contain (TC) a specified volume at the calibration temperature, with a single permanent calibration mark on the neck for accurate volume setting.

All models conform to Class ‘A’ accuracy requirements as per ASTM E-288 and USP (US Pharmacopoeia) specifications, offering tight tolerances and high repeatability. Clear, permanent graduation markings ensure excellent readability and reduced parallax error.

To suit different laboratory needs, REILGLAS volumetric flasks are available in:

• Clear Glass – suitable for routine analytical and general laboratory use

• Amber Glass – recommended for light-sensitive solutions and reagents

Standard supply includes a Calibration Certificate, while laboratories requiring accredited traceability can opt for models supplied with a NABL-traceable Calibration Certificate.

Available capacities range from 5 ml to 2000 ml, with corresponding standard stopper sizes, making these flasks suitable for:

• Analytical and QC laboratories

• Pharmaceutical and chemical industries

• Research and academic institutions

• Environmental, food, and water testing laboratories

REILGLAS volumetric flasks combine international standard compliance, precise volume accuracy, and durable construction, making them a reliable choice for critical volumetric measurements.
