Large 11" × 18" Sterilization Chamber
Capacity is one of the biggest reasons to choose the Midmark M11.
The chamber measures approximately 11 inches in diameter and 18 inches deep, providing the space needed to process larger instrument loads than smaller tabletop autoclaves.
The M11 includes:
- Two large trays: approximately 9.1" × 15.3" usable area
- Two small trays: approximately 6.8" × 15.3" usable area
- Six-slot pouch rack
For practices processing multiple instrument sets throughout the day, the additional chamber space can help reduce the number of loads required compared with a smaller sterilizer.
Automatic Steam Sterilization
The Midmark M11 is designed to simplify routine instrument processing through automatic operation.
Pre-programmed sterilization cycles help staff select the appropriate cycle and run loads consistently without the hands-on pressure and temperature adjustments required by traditional manual autoclaves.
The M11 also features an automatic door, adding convenience to the sterilization workflow.
For practices moving from a manual autoclave, this automation can be one of the most significant reasons to upgrade.
Midmark M11 vs. Midmark M9
Both the Midmark M11 and Midmark M9 are automatic tabletop steam sterilizers. The primary difference is capacity.
| Feature | Midmark M11 | Midmark M9 |
|---|---|---|
| Chamber Diameter | 11" | 9" |
| Chamber Depth | 18" | 15" |
| Overall Width | 17.8" | 15.8" |
| Overall Length | 23.5" | 20.5" |
| Unit Weight | 99 lb | 82 lb |
| Best For | Higher instrument volume | Smaller practices / loads |
Choose the Midmark M11 if:
- Your practice processes larger instrument loads
- You regularly run multiple sterilization cycles
- You want additional chamber capacity
- Your available counter space can accommodate the larger unit
- You expect your instrument-processing needs to grow
Consider the Midmark M9 if:
- Counter space is limited
- Your instrument loads are relatively small
- You don't need the additional capacity of an 11-inch chamber
For practices debating between the two, the decision usually comes down to capacity versus countertop space.

Who Is the Midmark M11 Designed For?
The M11 is well suited for professional healthcare environments that routinely sterilize reusable instruments and need the capacity of a larger tabletop unit.
Typical environments may include:
- Medical practices
- Specialty clinics
- Outpatient facilities
- Podiatry practices
- Surgical practices
- Multi-provider offices
- Other healthcare facilities performing steam sterilization
The M11 is particularly attractive for practices that have outgrown a smaller tabletop autoclave but still want the convenience and footprint of a countertop sterilizer.
Is the Midmark M11 Right for Your Practice?
The M11 makes the most sense when capacity is a priority.
If your staff frequently waits for instruments to complete multiple smaller sterilization loads, moving to an 11-inch chamber may improve instrument-processing efficiency.
Before ordering, consider:
- Your typical instrument load
- Number of sterilization cycles performed each day
- Available countertop space
- Electrical requirements
- Instrument and cassette dimensions
- Future growth in procedure volume
For lower-volume practices where space is more important than maximum capacity, the smaller Midmark M9 Steam Sterilizer may be worth considering.
