In-House = An Integrated Approach

Close Ties Between Every
Department of Our Company.

Our goal is to supply you with the highest quality and most up-to-date technology available at an affordable price.  From development and component assembly to testing and systems integration, the TDT teams take care of everything.

This belief is exemplified by the integrated nature of our facility, which brings together our team of scientists, on-site laboratory, engineering staff, and manufacturing floor all under one roof

In-House = Engineering

Reliability, Affordability, and Performance You Deserve

To meet the needs of our customers, we invest heavily in the most advanced manufacturing machinery and systems. Matching our advanced design and engineering with state-of-the-art production equipment allows us to consistently deliver the industry’s best research equipment.

In-House = Manufacturing

Our Manufacturing Department is Only Steps Away

At Tucker-Davis Technologies, we don’t build our systems around off-the-shelf boards; we build complete systems from the ground up.

We’re able to streamline the entire product development process, from concept to delivery, significantly reducing the cost of each new product we roll-out. With immediate feedback from the production staff, the reaction time for product improvements and upgrades is very fast.

In-House = Customer Support

We know our products and we know your work

Our Technical Support Engineers and Application Specialists have advanced degrees in Biomedical Engineering from top-flight schools and many have research experience in neuroscience and physiology.

This real-world experience means that the people who work with you not only have an intimate knowledge of our equipment but also understand your needs and your research.

Continuity into the Future:

TDT offers the most complete line of cost-effective systems for neurophysiology research. From our student-focused Lab Rat all-in-one devices to our very-high channel count cluster systems, all of our systems are unified in their operation and they all run TDT’s Synapse Software. This means experiments you build for your very first system will continue to work smoothly as your needs grow in the future.
