About Us

TSS Microscopy has the depth to match the instrument support needs you would expect from an OEM with a genuine priority on every customer’s success.

TSS Microscopy offers a diverse selection of pre-owned electron and ion microscopes. Each scope is meticulously remanufactured to its original performance specifications and is ready to serve any lab. And to assure that our customers achieve their goals, wherever they are in the world, we offer service support, maintenance programs, applications training and instrument operation training via our global team of engineers.

Our Team

TSS Microscopy started operations in 2003 as Technical Sales Solutions, a company founded to address the growing need for cost-effective options that allowed more labs to obtain high-performance SEM and FIB. Since then, with hundreds of SEM, TEM, FIB and dual beam installations completed worldwide, we’ve grown our team and our support offerings to become more than an equipment re-seller. We are proud to now be a full-service solution provider in the electron microscopy market. Remanufactured instruments are a great way to stretch budgets while still enabling leading edge research. We also support customers with accessories, consumables, service and training and alleviate uncertainty about investing in a pre-owned equipment. Whether buying or selling, we stand with you at every step of the process. We can handle all the logistics – from consulting, packing and crating, delivery, and installation, to comprehensive training, warranty, and reliable after-care maintenance. Our inventory features microscopes from all major manufacturers, enabling us to focus on finding the instrument solution that is right for your application needs.

Remanufacturing Process

All instruments sold by TSS Microscopy undergo a detailed process to ensure that they meet the original OEM performance specifications at the customer site. Our engineers don't just replace parts; they dig in deeper to fully understand and test each instrument.

Identify Concerns

Identify Concerns

Each instrument is thoroughly inspected to document the areas requiring attention.



To remanufacture a tool properly, we disassemble and clean the core systems, replace hoses, o-rings, probe electronics, and replace consumables.

Replace and Repair

Replace and Repair

Hardware is inspected and repaired or replaced as needed. IGPs, out of date power supplies, and more are replaced.



Once selected, each system is configured to its new owner's specifications and tested to validate quality and performance.


"You get all of the functionality and advantages of the system, without paying the price of a new one."

“Compared to scope OEMs we have used previously, TSS has more engineering experience and willingness to explore opportunities that would not be possible with other companies."
