Masterpiece Laboratories is an online marketplace for sales of vintage lab equipment. Search our used and vintage lab equipment some of which are operational, some needs repair, and others are just for parts. None of the equipment is refurbished and therefore will be sold as-is with a policy of no return. That said, we are happy to discuss all products and clarify their current state of use if you contact us via phone or email. If manuals are available, they will also be provided with the equipment. Our vintage lab products are for testing laboratories, chemists, engineers, academic universities, set designers, and collectors.
