Laboratory and Scientific Operations

Locate any sample and prove its custody history—on demand

A lab can't quickly locate a specific sample or prove its chain of custody, because location and handoff aren't logged consistently between staff. Build a system where every location change and handoff is recorded automatically.

A custody gap is a legal and quality problem, not just an inconvenience

When location changes and handoffs aren't logged consistently, a sample's chain of custody has gaps that can invalidate a result entirely—especially in regulated or legal contexts where custody has to be provable.

Require every handoff to record both the giving and receiving party, so custody history is complete by design, not by discipline.

From logging to disposal
  1. 1. Sample is logged with a barcode and initial location
  2. 2. Every location change and handoff is recorded
  3. 3. Sample is checked out for testing and checked back in
  4. 4. Chain-of-custody history is retained for the sample's lifetime
  5. 5. Sample is disposed of per policy, closing the record

What the system tracks and automates

Records

Samples, locations, handoffs, custody history, disposal records.

Automations

Location-change logging, custody-gap alerts, and disposal-schedule reminders.

Custom logic

Sample-type-specific retention requirements, and custody-transfer approval rules.

Platform

Own the application. P2HS runs the platform.

Example build brief

Example prompt
Build a laboratory sample tracking app with barcode-based sample logging, location and handoff tracking, chain-of-custody history, and scheduled disposal.

Scenarios to test in your preview

  • A handoff must record both the giving and receiving party, not just a location change.
  • A sample must not be marked disposed without its full custody history retained.
  • A checked-out sample must be visibly distinct from one that's checked in and available.
FAQ

Common questions about sample tracking software

Who is this for?

Labs, forensic units, and any organization that needs a provable chain of custody for physical samples or evidence.

Does this include testing and results?

Pair this with a LIMS for the full sample-to-report workflow.

Does this apply beyond lab samples?

Yes—the same custody-transfer model applies to evidence, regulated materials, or any item requiring provable custody history.
