Courier packing checklist: step-by-step for lab samples
Concrete, verifiable steps to pack lab samples for courier pickup. Focus on measurements, sealing methods and control points for Swiss shipments.
Quick answer
Prepare lab samples so they are sealed, stable and documented for courier pickup in Switzerland. Follow this checklist: identification, primary container leak test, secondary containment, cushioning, outer packaging and taping, temperature control if needed, and documentation. Verify all items before handing to the courier.
1. Preparation: ID and paperwork
Label each sample with name, sample ID and shipment number. Include a packing list or lab report (two copies: one inside the outer package, one attached outside). Add temperature requirements and a contact person with Swiss phone number.
2. Primary container: leak test and closure
Use approved primary containers (e.g. screw vials with O‑ring). Perform a simple leak test: close the container and lay it on its side for 2 minutes; no drops should appear. Replace any faulty containers.
3. Secondary containment: absorbents and cushioning
Place each primary container in a leak‑proof secondary bag (resealable or heat‑sealed). Use absorbent material able to hold at least three times the liquid volume. Add cushioning layers (foam or bubble) to protect against shocks.
4. Outer packaging: strength and taping methods
Choose a sturdy outer box with a minimum wall strength equivalent to 10 mm or high‑grade corrugated board. Seal with 50 mm PVC tape or 48–60 mm paper tape, applying at least three overlapping strips over openings. Use a cross‑seal (one strip lengthwise, one crosswise). Label the box with recipient, sender and “Lab sample”.
5. Temperature and monitoring
If temperature sensitive, add a single‑use data logger or temperature indicator strip. Record start temperature before packing (e.g. 4 °C). For chilled samples use appropriate cold packs separated from the primary container by insulation to avoid direct contact.
6. Final visual check before pickup
Complete this quick checklist: correct labeling? Primary container sealed? Secondary bag intact? Absorbent present? Outer package closed and taped? Documentation attached outside? Record packing time and person responsible.
Frequently asked questions
Which taping method is best for outer boxes?
Use 50 mm PVC tape or 48–60 mm paper tape with at least three overlapping strips. A cross‑seal (one strip lengthwise and one crosswise) increases strength and security.
How do I test a primary container for leaks?
After closing, place the container on its side for two minutes on a clean towel. No moisture or droplets should appear. Replace containers that leak or show damage.
Do lab samples need special outer labelling?
Label the outer package with sender, recipient, ‘Lab sample’ and contact details. Include temperature notes if relevant. Do not use hazardous goods pictograms unless the sample is regulated as such.
What documents should accompany the samples?
Include a sample list with IDs, sender and recipient details, test instructions, contact phone number and temperature requirements. Place one copy inside and one copy outside the package.
