Before accepting a lab reagent from a vendor, it’s important to carefully inspect it to ensure quality, safety, and compliance with laboratory standards. Here are key things an end-user should check before taking delivery of a reagent:
1. Expiry Date
Always verify the expiry date on the label. Expired or nearly expired reagents can affect the accuracy of your tests and experiments. If the reagent has a short shelf life remaining, consider whether it will be used up before it expires.
2. Packaging and Seal Integrity
Check the reagent container for any damage, cracks, or leaks. Ensure that the seal is intact and has not been tampered with. A broken seal may indicate contamination or improper handling.
3. Labeling and Product Information
Make sure the reagent label includes:
✅ Correct chemical name and concentration
✅ Batch/Lot number (for traceability)
✅ Manufacturer’s name and certification
✅ Storage and handling instructions
✅ Hazard symbols and safety precautions
If any of this information is missing or unclear, request clarification from the vendor before accepting the reagent.
4. Storage Conditions During Transport
Some reagents require cold storage, protection from light, or controlled humidity. Before accepting the reagent, confirm that it was transported under the correct conditions to prevent degradation.
5. Safety Considerations for Hazardous Reagents
For hazardous reagents (flammable, toxic, corrosive, etc.), ensure that:
✅ The correct hazard symbols are on the label
✅ The Material Safety Data Sheet (MSDS) is available
✅ You have the necessary PPE (gloves, goggles, lab coat, etc.) for handling
If the reagent is highly reactive or sensitive, confirm that the vendor followed proper transport regulations.
6. Quantity and Order Accuracy
Cross-check the reagent name, concentration, and quantity with your order request or invoice. Ensure you are receiving exactly what was ordered to prevent errors in your laboratory work.
7. Vendor Reputation and Certification
If you are buying from a new vendor, check their certifications (ISO, GMP, etc.) and past reviews to ensure they supply high-quality, authentic reagents. Counterfeit or substandard reagents can lead to inaccurate results and safety risks.
Final Thoughts
Before accepting any lab reagent from a vendor, inspect the expiry date, packaging, labeling, storage conditions, and safety details. This careful checking process helps ensure reagent quality, prevents contamination, and supports accurate experimental results.
