Calibration and graduations

Confirm the graduation interval, calibration class and volumetric tolerance for your chosen capacity. The previous description gives 0.1 mL divisions, mentions Class A / Class B and quotes ±0.05 mL for a 50 mL Class A example, but does not establish which specifications apply to the supplied options. No accuracy class or tolerance is guaranteed across this listing.

Calibration temperature and certificate availability are not specified. Select glassware with verified specifications where your analytical method requires a particular class or tolerance.

Use and care

Confirm compatibility of the glass and stopcock with your reagents; do not assume suitability for every aqueous or organic solution. Follow the manufacturer's instructions for stopcock care, cleaning, filling and volume readings. Support the burette securely and inspect it for damage before use.

A stand, clamp and other accessories are not documented as included.
