Product Description
These Erlenmeyer flasks are designed for precision laboratory work, featuring a conical body, narrow mouth, and approximate graduation for easy volume estimation. Manufactured from premium chemical-resistant glass, they comply with IS 1381-1 and ISO/DIN 1773 standards, ensuring outstanding quality and reliability for research, quality control, and teaching applications.
Available in a broad range of capacities (5 mL to 5000 mL), these flasks accommodate everything from microscale titrations to large-volume sample preparation. Select sizes are ungraduated (5 mL, 10 mL, 150 mL) or not covered in standard for specific tasks. Graduated intervals from 10 mL up to 500 mL are marked for convenient measurements, while larger flasks offer intervals of 100–500 mL for easy observation and reagent mixing.
