BioSurplus Team

In order to offer a high quantity of quality laboratory equipment that has been used, we needed to assemble a core management team that not only understood the equipment, but how to track it, evaluate it and manage an ever-changing inventory. To that end, every BioSurplus core team member has at least 18 years of skilled experience — with in-depth experience that includes operations, scientific instrumentation, biotech, high-tech, and software architecture and development.
