Why Class A Serialized
Each Class A burette in this range is individually serialized and carries a tighter volumetric tolerance than a Class B burette, which is why it is specified for certified accuracy work and tender compliance where a traceable calibration record is required. It is calibrated to ASTM E287 and traceable to NIST standards, and is supplied with a certificate of identification and capacity so the individual unit's accuracy can be verified against its serial number. For routine teaching use where this level of certification isn't required, see Burette Class-B with PTFE Key Stopcock.
