Glass Graduated Burette with Straight PTFE Stopcock, AS Class

The graduated clear glass burette, made of borosilicate 3.3 and classified as class AS, is an essential instrument for the precise dosing of liquids in analytical chemistry laboratories. Its design and manufacturing quality ensure accurate and reproducible measurements, making it especially suitable for demanding titrations and volumetric tests.

The use of borosilicate 3.3 glass provides excellent chemical resistance and low thermal expansion, allowing work with a wide variety of reagents without compromising material stability or measurement accuracy. This feature, along with its transparency, facilitates a clear reading of the meniscus during the dosing process.

Manufactured in accordance with ISO 385 standard, this burette complies with international standards for precision and quality. Its calibration under the EX criterion ensures that the volume dispensed faithfully corresponds to the value indicated on the scale, improving the reliability of the results in each operation.

The AS classification combines maximum accuracy with fast and efficient emptying, optimizing working time without affecting precision. The discharge system incorporates a straight stopcock made of PTFE, a highly resistant material that allows precise and uniform flow control, guaranteeing safe and constant dosing.

Each unit is produced under rigorous quality controls and may include traceability according to metrological standards, reinforcing its use in environments where accuracy is critical. Its robust design and compliance with international regulations make it a reliable tool for research, quality control, and chemical analysis laboratories.

Available in different capacities, this burette adapts to multiple laboratory needs, offering a balanced combination of precision, durability, and ease of use in professional applications.
