Description
The Newmed Kronos B 23 is a Class B dental steriliser built for practices that need reliable, high-throughput sterilisation without compromise. With a 23-litre chamber, motor-operated door locking, and Midmark’s patented QuikSteam technology, this Kronos B 23 autoclave delivers consistent, verifiable sterilisation across wrapped, hollow, and porous loads.
Built for High-Throughput Sterilisation
In any dental practice, the autoclave dictates the pace of your instrument turnaround. A reliable Class B dental steriliser means fewer bottlenecks between patients and confidence that every load – regardless of instrument type – is processed to standard.
For practices running multiple surgeries or high patient volumes, that versatility matters.

Frequently Asked Questions
What does Class B mean in a dental steriliser?
Class B refers to the highest classification under EN 13060 for small steam sterilisers. A Class B dental steriliser incorporates a vacuum stage, allowing it to effectively sterilise wrapped instruments, hollow items such as cannulae and tubing, and porous loads like fabrics and swabs – load types that lower-class sterilisers cannot reliably process.
How does the Kronos B 23 support compliance and record-keeping?
The built-in printer automatically records every sterilisation cycle as it runs, producing a physical printout that can be filed against patient or instrument records. An optional USB data logger is also available for practices that prefer or require digital record-keeping.
What is the chamber capacity of the Kronos B 23?
The Kronos B 23 autoclave has a 23-litre chamber and comes with a 4-tray system as standard. Tray dimensions are 185mm wide by 440mm deep by 18mm high, suitable for a range of wrapped and unwrapped dental instrument loads. Need something a little smaller? We also stock the Newmed Kronos B18 which features an 18-litre chamber.
Does the Kronos B 23 require a specific water supply?
Like most Class B dental sterilisers, the Kronos B 23 requires distilled or demineralised water for safe and effective operation. A built-in water quality sensor monitors the supply throughout each cycle and alerts the user if quality falls below the required standard. Specific water supply requirements should be confirmed with our team prior to installation.
