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. 

Key Features
  • 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. 
 
Accuracy & Tolerance
Class B flasks have a higher tolerance (margin of error) compared to Class A, typically around double the Class A limit.
