The Tuttnauer 3870M is one of the largest and most powerful manual gravity autoclaves in the industry. With a massive 15" × 30" chamber, it is engineered for clinics requiring high-volume sterilization, large pack capacity, long instruments, oversized cassettes, drapes, and bulk loads.
With no electronic boards or software, the 3870M combines extreme chamber capacity with maximum reliability. Its manual mechanical design makes it highly durable and easy to maintain — ideal for surgical centers, hospital departments, dental group practices, veterinary hospitals, and high-throughput sterilization areas.
This model is the perfect solution for practices needing large load sterilization without the complexity of a fully automatic or Class B system.
Ideal for clinics that need:
A large, 75-liter chamber
High-volume daily sterilization
Long instruments, surgical trays, large cassettes
A reliable mechanical system with no electronics
Low-maintenance, gravity-based sterilization
If your practice does not require Bowie–Dick testing, vacuum-based hollow load validation, or automated documentation, the Tuttnauer 3870M is the correct model.
