Local aliquot planning and traceability

Aliquotcairn

Build a mass-balanced aliquot plan, assign coded child tubes, map rack positions, record actual transfers, and export a durable evidence packet without an account or cloud service.

From source to handoff

Every transfer stays explainable

Aliquotcairn keeps planned values, actual entries, parent-child identifiers, rack coordinates, exceptions, and handling history in one local project.

A run checklist separates the approved plan from actual transfers and documented exceptions.

Built for technical work

Useful controls, visible boundaries

Calculations come directly from the values you enter. Aliquotcairn records decisions and evidence; it does not decide specimen suitability, storage conditions, or acceptance.

Coded intake

Source ID, material, volume, concentration, lot or run, received time, storage condition, location, and notes.

Mass-balanced plans

Requested count, target volume, capacity, dead volume, protected reserve, operator, SOP reference, destination, and rack dimensions.

Traceable rack maps

Deterministic tube IDs, independent coordinates, planned and actual volumes, statuses, locations, notes, and handling cycles.

Execution records

Controlled checklist, transfer queue, operator attribution, actual values, held exceptions, and timestamped custody events.

Evidence packets

Bench PDF, tube-manifest CSV, event-history CSV, structured JSON snapshot, Code 128 label PDF, and SHA-256 record fingerprint.

Local privacy

No account, analytics, advertising, tracking, cloud database, camera, microphone, location, contacts, or photo permission.

Primary references

Methods should be inspectable

These sources informed Aliquotcairn's record fields and consistency checks. They do not make the app a validated laboratory system or replace local procedures and qualified review.
