Laboratory Burette - Precision Glassware for Titration and Volume Measurement #40309 (License: Personal Use)

This is a high-precision glass burette, typically 50 mL capacity, with evenly spaced graduation marks from 0 to 50 mL (top to bottom) and a controlled stopcock at the base for dispensing liquids dropwise. The transparent borosilicate glass ensures chemical resistance and visibility, while the ground-glass or PTFE stopcock minimizes leakage and allows fine flow control. It is commonly used in analytical chemistry for volumetric titrations to determine unknown concentrations.

Used in academic labs, quality control, and research settings for quantitative chemical analysis; matches user intent for educational resources, lab equipment procurement, or protocol documentation.
