How to Buy Used Laboratory Equipment

1. Specify before you shop

• Write down the analyses, detection limits and throughput required
• Identify mandatory configuration: detector type, autosampler, column oven, software
• Note facility constraints: bench space, power, ventilation, gases, cooling
• Decide whether the software must satisfy data integrity requirements
• Set a decision deadline, since good units move quickly

2. Understand who you are buying from

• Manufacturer-certified programmes: highest cost, strongest support and warranty
• Specialist dealers and refurbishers: variable, so ask what refurbishment included
• Laboratory direct sales and surplus: cheapest, usually sold as-is with no support
• Asset auctions: fast and cheap, with little recourse and often no testing
• Ask what testing was performed and request the report, whoever you buy from

3. Inspect and verify

• Ask for the serial number and confirm model support status with the manufacturer
• Request a functional demonstration and, ideally, data on a known sample
• For chromatography, ask about pump seals, injector wear, detector lamp or source hours
• For mass spectrometry, ask about source condition, vacuum performance and pump hours
• For microscopy, confirm optics, stage and detector condition and alignment
• Confirm all accessories, cables, tools, licences and manuals are included
• Ask about decontamination status and prior sample types

4. Shipping and installation

• Use riggers experienced with laboratory instruments for heavy or sensitive equipment
• Confirm who crates, insures and is liable for transit damage
• Plan utilities and site readiness before delivery, not after
• Budget for professional installation and performance verification
• Schedule your own qualification activities before results are released

5. Protect yourself commercially

• Get warranty terms and duration in writing, including what voids them
• Agree acceptance criteria and a return path if the unit fails verification
• Confirm software licence transfer in writing before payment
• Avoid paying in full before inspection or verified delivery where avoidable

A note on pricing

We do not publish instrument or software prices. Real transaction prices depend on configuration, condition, accessories, service coverage, installation, region and negotiation, and published list figures are rarely what a laboratory pays. Where you need a figure to plan with, request quotations against a written specification.
