Answers to common questions about buying and selling used industrial automation and laboratory equipment through PLC North. Have a question that’s not covered here? Contact us directly.
Is your equipment tested before it’s listed?
Yes. Every item that comes through PLC North is tested and verified before it goes up for sale — that’s why you’ll see a “Tested & Verified” badge on our product pages. Our testing process is specific to each category of equipment, covering things like power-on checks, functional tests, and (for lab instruments) performance verification rather than just a visual inspection.
What’s the difference between your two product divisions?
We split our inventory into two categories: Industrial Automation Systems (PLCs, HMI panels, drives, sensors, and related components from brands like Siemens, ABB, and Phoenix Contact) and Laboratory & Analytical Equipment (HPLC systems, GC/GCMS systems, vacuum pumps, and related lab instrumentation from brands like Shimadzu, Edwards, and Pfeiffer).
How do I know a part will fit my system?
We list the full manufacturer part number in the product title and description wherever one exists, not just a general description — so you can match it directly against your system’s nameplate or existing part before ordering. If you’re ever unsure whether a listed part matches your equipment, contact us before purchasing and we’re happy to help confirm.
Do you sell anywhere besides your website?
Yes, we also list inventory on eBay. Our website is where we list our full catalog, including higher-value lab equipment that isn’t always mirrored on eBay.
Can I sell my used lab equipment to PLC North?
Yes. We work with labs and facilities that are upgrading instruments, closing projects, or clearing out equipment, and can help with documentation, decontamination requirements, and valuation as part of the process. Contact us with details of what you’re looking to move, and we’ll help you figure out the best path forward.
Do you ship internationally?
Yes, we ship worldwide. Shipping cost and timeframe depend on the size and destination of the item — contact us for a quote on a specific product.
Can’t find the specific part or instrument you need?
If it’s not currently listed on our site, reach out through our Source It For Me page and let us know what you’re looking for. We regularly source parts and equipment beyond what’s actively listed.
