Volumetric Flask Class B with Stopper

The OMSONS Class B Volumetric Flasks (Clear) are designed for general laboratory work where standard precision is required rather than the extreme accuracy of Class A. These flasks are calibrated to contain (TC, In) a specific volume and are printed with high-visibility blue enamel markings. 

• Accuracy Standard: Complies with DIN/ISO 1042 standards.
• Calibration: Typically calibrated at 20°C.
• Material: Manufactured from Borosilicate 3.3 glass, which is highly resistant to chemical corrosion and thermal shock.
• Closure: Usually supplied with a compatible glass stopper or plastic/PTFE stopper to prevent evaporation and leaks.
• Printing: Features permanent blue enamel printing for the capacity, tolerance, and calibration line, which is resistant to acid boiling and scratching. 

• General Mixing: Preparing non-critical solutions or buffers where slight concentration variations are acceptable.
• Educational Labs: Cost-effective for schools and undergraduate teaching labs where durability and price are prioritised over analytical precision.
• Approximate Volume Measurements: Used in preliminary testing phases.
