Burette - Precision Volumetric Glassware for Titration Experiments #3876688 (License: Personal Use)

This is a calibrated volumetric burette, typically made of borosilicate glass, featuring a fine-bore tube with precise volume graduations (e.g., 0-50 mL), a ground-glass or PTFE stopcock for controlled liquid release, and an “Ex 27°C” calibration mark indicating it’s calibrated to deliver (ex) at 27°C. The top reservoir holds liquid above the zero mark, and the meniscus is read at eye level for accuracy. It is used primarily in acid-base and redox titrations to dispense titrant with ±0.05 mL precision.

Used in educational and research chemistry labs during titration procedures; users search for “buret vs pipette”, “how to read a burette”, or “lab glassware identification”. Ideal for instructional pages, lab manuals, or e-commerce product listings for scientific equipment.
