REILGLAS Volumetric Flasks – ISO 1042 Class ‘A’ are high-precision laboratory glassware designed for the accurate preparation, dilution, and storage of standard solutions. Manufactured from high-quality, chemically resistant glass, these flasks ensure dimensional stability, excellent transparency, and long service life.

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 27°C, with a single permanent calibration mark on the neck for precise volume setting.

All flasks conform to Class ‘A’ accuracy requirements as per ISO 1042 / IS 915:2012, offering tight tolerance limits and high repeatability. Clear, permanent markings ensure excellent readability and reduced parallax error.

To meet diverse laboratory requirements, REILGLAS volumetric flasks are available in:

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

• Colour-Coded Glass – enables quick identification of capacities and reduces handling errors in multi-sample environments

A Calibration Certificate is supplied with each flask, confirming compliance with Class ‘A’ specifications. Selected low-capacity flasks (1–2 ml) are supplied in test tube shape, and certain high-capacity models are not covered under ISO standards, as specified.

Available capacities range from 1 ml to 5000 ml, with standard ground-glass stopper sizes matched to each volume, making these flasks ideal for:

• Analytical and QC laboratories

• Pharmaceutical and chemical industries

• Research and academic institutions

• Environmental, food, and water testing laboratories

REILGLAS ISO 1042 Class ‘A’ volumetric flasks combine international standard compliance, precise calibration at 27°C, and durable construction, making them a reliable choice for critical volumetric measurements.
