Photolithography Acid-Base Burette (Class A, EX) (High-Borosilicate)

Description

Product Introduction:

The photolithographically engraved acid burette (Class A EX) is a high‑precision, chemically resistant, and high‑temperature‑tolerant core laboratory measuring instrument, specifically designed for the accurate titration and volumetric analysis of acidic and strongly oxidizing solutions. It features a high‑borosilicate glass body with laser‑etched graduations and complies with Class A metrological standards and the EX (delivery) calibration specifications.

Application scenarios

1. Chemical analysis: volumetric analyses such as acid–base titration, redox titration, complexometric titration, and precipitation titration.

2. Research and Teaching: Precision metrology and experimental teaching in university and research institute laboratories.

3. Industrial Inspection: Quality control and compositional analysis in industries such as food, pharmaceuticals, environmental protection, chemicals, and electronics.

4 Standard Metrology: Calibration of standard solutions and traceability of measurement values by metrological institutions and third-party testing laboratories.
