Bulk Coating Replenishment: Prevent Mixing Different Batch Identities

Topping up a working supply vessel with another batch makes later traceability more complicated. The vessel may then contain material from several production histories.

Updated · NANOLAB Knowledge

Practical approach

Empty and manage the vessel through an approved procedure before changing batches, or use a documented method that explicitly tracks the mixture and has supplier approval.

A half-full dispensing bottle from batch A is topped up from batch B. A later complaint cannot be assigned exclusively to either batch from that bottle's label alone.

Decision limits

Do not invent a new batch identity that conceals the original inputs. Keep the relationship between source batches and filled units recoverable.
