AI-editedFounded by Thomas Wenzel, KeT Boxsysteme draws on over 20 years of experience in the field of gloveboxes. For several years now, our company has specialized in giving used equipment a second life—instead of disposing of it. Through professional decontamination, technical overhauls, and custom modifications, we transform these units back into fully functional gloveboxes.
As a family-owned business, we stand for reliability, meticulous service, and customized solutions—for laboratories that are closing, relocating, or restructuring.
KeT Boxsysteme & ML-Resale – A Strong Partnership with Family Roots
One of the distinctive features of KeT Boxsysteme is its close collaboration with ML-Resale, a company that specializes in the sale of used gloveboxes.
The sale of used glove boxes is handled entirely through ML-Resale. While KeT Boxsysteme is responsible for the technical refurbishment, upkeep, and maintenance of the equipment, ML-Resale handles consulting and sales.
But there is more to this collaboration than a traditional business partnership: ML-Resale is led by Michael Lange, the brother of KeT owner Thomas Wenzel.
As brothers, we combine our respective strengths and many years of experience to offer our clients a comprehensive range of services.
Whether you're purchasing a used Glovebox, making custom modifications, having it professionally refurbished, or arranging for long-term maintenance—thanks to our close collaboration, you'll receive all these services from a single source.
Two brothers, two companies—a shared commitment to quality, reliability, and personalized service.
