Two brothers, two companies—one team
Behind KeT Boxsysteme and ML-Resale are two brothers. I, Thomas, handle all the technical aspects—refurbishment, modifications, maintenance, and service. My brother Michael handles consulting and sales of used gloveboxes at ML-Resale. This way, you receive tested equipment with comprehensive service—all from a single source.
AI-editedTwo people who stand up for each other
We aren't two unrelated companies with a business relationship—we're family. You'll notice this in our direct communication, honest answers, and the fact that we both stand behind our work with our names on the line.
When you contact Michael, my workshop is always there in the background—and vice versa. For you, this means: a dedicated point of contact, no miscommunication, and, if in doubt, someone who truly takes responsibility.
We’re glad you’d like to learn more about us. I’m Thomas Wenzel, owner of KeT Boxsysteme. I’ve been working with gloveboxes for over 20 years and know every system inside and out. Together with my brother Michael, who runs ML-Resale, we’ve divided up the used glovebox business so that each of us does what we do best.
From refurbishment to after-sales support
At KeT, I don’t just handle the technical aspects in the narrow sense—I oversee the entire technical process for every unit:
- Complete refurbishment & decontamination—every glovebox is professionally refurbished, cleaned, and made ready for operation.
- All technical functions—seal integrity, gas purification, controls, and sensors—are tested; the system isn’t shipped out until everything is working flawlessly.
- Modifications according to your specifications—airlocks, feed-throughs, and customizations tailored precisely to your application.
- Maintenance & Service – maintenance, repairs, and replacement parts, even years after purchase.
- After-sales support – with a maintenance contract available upon request to ensure your system operates reliably over the long term.
Michael & ML-Resale: Consulting and Sales
My brother Michael has a background in sales and guides buyers from the initial inquiry through the selection process to delivery. The sale of used gloveboxes is handled entirely through ML-Resale—this allows me to focus 100% on the systems, while you have a dedicated contact person for all business matters. You can purchase new systems from MBraun directly from KeT.
Here’s how it all works
- You make an inquiry. Michael discusses your requirements, helps you select a model, and provides a quote.
- KeT prepares the equipment. This includes refurbishment, functional testing, and—if desired—modifications according to your specifications.
- Together, we deliver. KeT handles delivery, installation, and commissioning—across Europe and ready for operation.
- We stay on top of things. Maintenance, service, and—if desired—a maintenance contract ensure that your system remains reliable.
What this means for you
- Everything from a single source—consulting, refurbishment, delivery, and service.
- Technology from a specialist company—over 20 years of experience back every system.
- Custom-fit instead of off-the-shelf—modifications tailored precisely to your application.
- We’re here for you even after your purchase—maintenance, service, and maintenance contracts.
- Honest and reliable—as a family, we stand behind our name.
