Lot
A quantity of material produced under uniform conditions and identified by a unique number so results and records can be traced to it; often used interchangeably with 'batch', though usage can differ by organization.
In plain language
A specific production run, tagged with a number so its test results can be traced back to it.
Why it matters in research
