Why Choose the Serialized Version
Unlike the unserialized version of this flask, each Serialized flask carries its own individual identification number etched onto the glass, which matters when a lab needs to trace a specific flask back to a calibration record, a batch certificate, or an audit trail — common requirements in accredited testing labs and pharmaceutical QC. Where that traceability is not required, the unserialized version of the same Class-A amber flask is a lower-cost equivalent.
