Why Regular Brush Cleaning Matters
Residue left inside a burette's bore — from earlier titrations, grease, or hard-water deposits — can affect how liquid drains along the glass wall and interferes with an accurate meniscus reading. A soft-bristled burette brush, used with laboratory detergent and a final distilled-water rinse, is the standard way to keep the bore clean without scratching the glass, which a harder brush or an abrasive could do.
