Overview
The Tuttnauer 2340M is a manual tabletop steam autoclave designed for organizations that need dependable sterilization without the complexity of a fully electronic sterilizer. Its 19-liter chamber provides useful capacity for compatible instruments and other heat- and moisture-resistant materials while maintaining a compact benchtop footprint.
The 2340M belongs to Tuttnauer's established M Series of manual autoclaves. Instead of touchscreen controls, connected software, or advanced electronic cycle management, the system uses a straightforward manual control panel built around a pressure gauge, timer, thermostat, and function selector. This gives trained operators direct control over the sterilization process and can make the 2340M particularly attractive to facilities with established operating procedures.
Its cylindrical chamber measures approximately 9 inches in diameter by 18 inches deep. The chamber accommodates three trays measuring approximately 16.3 inches long × 6.7 inches wide × 0.8 inches high and can accommodate two full-size and two half-size standard cassettes.
Durability is another important part of the 2340M design. Tuttnauer uses an electropolished chamber and door intended for long service life, while the relatively uncomplicated control architecture can appeal to organizations that value straightforward operation and serviceability.
The system also incorporates a double safety door-locking mechanism, dual safety thermostats, and automatic shutoff protection against overheating. A front-mounted drain valve simplifies routine reservoir drainage without requiring users to reach behind the sterilizer.
For laboratories replacing an older manual autoclave, the 2340M offers the opportunity to stay with a familiar, proven operating format while purchasing brand-new equipment with current manufacturer warranty coverage.

Tuttnauer 2340M Ideal Laboratory and Facility Environments
The Tuttnauer 2340M is particularly well suited for facilities that need reliable steam sterilization but do not require the automation, electronic recordkeeping, connectivity, or vacuum systems found on more sophisticated tabletop autoclaves.
Research and academic laboratories can use the 2340M for appropriate reusable tools, glassware, instruments, and other compatible steam-sterilizable materials. Its relatively compact dimensions allow it to fit into laboratory support areas where available counter space may be limited.
Veterinary, medical, dental, and other professional facilities may also benefit from the 2340M when processing compatible routine instrument loads. The combination of a 19-liter chamber and relatively fast hot-start cycle can support facilities running multiple small-to-moderate loads throughout the working day.
The 2340M can also serve as a practical secondary or backup autoclave in larger facilities. A laboratory with a larger floor-standing sterilizer may still benefit from a smaller tabletop system for routine instruments and smaller loads, reducing unnecessary use of higher-capacity equipment.
Its 120 V electrical configuration can simplify installation in existing facilities where higher-voltage service may not be readily available.
Organizations should also consider the 2340M when long-term simplicity is a priority. A manual autoclave eliminates many of the electronic and connectivity features found on current-generation systems. For users who do not need those capabilities, a simpler platform may provide a better match for the actual workflow.
Manual Steam Sterilization
The Tuttnauer 2340M uses saturated steam under pressure to sterilize compatible heat- and moisture-resistant materials.
The system operates using gravity displacement rather than an active pre-vacuum system. As steam enters the chamber, cooler air is displaced from the sterilization environment, allowing the chamber and properly arranged load to reach the required sterilization conditions.
Gravity displacement remains a practical approach for many routine solid loads. Proper loading and cycle selection are important because trapped air can interfere with effective steam contact.
The manual control system gives trained operators direct control over cycle operation. This simplicity can be useful in facilities with established sterilization protocols and personnel who are comfortable operating manual equipment.
Facilities that routinely sterilize complex hollow, porous, packaged, or vacuum-dependent loads should compare the 2340M with Tuttnauer models offering automatic or active pre-vacuum processing.
As with any autoclave, appropriate cleaning, loading, monitoring, water quality, maintenance, and cycle selection are essential to reliable sterilization.
Tuttnauer 2340M Chamber Capacity and Workflow
The Tuttnauer 2340M provides approximately 19 liters, or 5 gallons, of chamber capacity. Its cylindrical chamber measures approximately 9 inches in diameter by 18 inches deep, or 230 × 470 mm.
The system includes three trays measuring approximately 16.3 inches long × 6.7 inches wide × 0.8 inches high. Tuttnauer lists standard cassette capacity at two full-size and two half-size cassettes.
The smaller chamber gives the 2340M a somewhat different role than the larger 2540M. While the 2540M provides 23 liters of capacity and a 10-inch-diameter chamber, the 2340M provides a more compact 19-liter alternative for facilities whose routine loads do not require the additional space.
The 2340M also offers relatively quick turnaround for routine unwrapped loads. Tuttnauer lists its standard unwrapped cycle at approximately 27 minutes from a cold start and approximately 13 minutes from a hot start. Actual times can vary according to instrument load and operating conditions.
The faster hot-start cycle can be particularly useful when several loads are processed consecutively. Once the sterilizer is already at operating temperature, subsequent routine cycles may require significantly less time than the initial cycle of the day.
For facilities comparing tabletop autoclaves, chamber size should therefore be considered alongside expected load size and daily cycle frequency. A larger chamber is not automatically better if most routine loads fit comfortably within the smaller 2340M.
Choosing the Right New Tuttnauer Autoclave
The Tuttnauer 2340M is a strong choice for facilities that prioritize simplicity, reliability, compact size, and straightforward 120 V installation.
The first consideration should be chamber capacity. At 19 liters, the 2340M provides less capacity than the 23-liter 2540M but also offers a slightly smaller 9-inch-diameter chamber. Facilities processing relatively modest loads may find the 2340M entirely sufficient without paying for chamber space they rarely use.
The 2540M may be the better choice when larger instruments, containers, or greater per-cycle capacity are important. Its chamber increases diameter from approximately 9 to 10 inches and depth from approximately 18 to 19 inches.
Automation is another important consideration. The 2340M is intentionally a manual machine. Organizations seeking touchscreen operation, automatic programs, digital cycle documentation, Wi-Fi connectivity, or more advanced air-removal capabilities should consider one of Tuttnauer's automatic T-Top, T-Edge, or other current sterilizer platforms.
For many laboratories, however, those features are not necessary. A facility with trained personnel, relatively straightforward loads, and established sterilization procedures may prefer the simplicity of the 2340M.
Electrical requirements are also convenient for many U.S. installations. The current 2340M operates at 120 V, 50–60 Hz, with approximately 1,400 W power consumption and a 12 A current requirement.
American Instrument Exchange can help customers compare the 2340M with the 2540M and other new Tuttnauer autoclaves based on actual load sizes, chamber requirements, workflow, available utilities, desired automation, and budget.

Installation and Utility Requirements
The Tuttnauer 2340M is designed for relatively straightforward benchtop installation.
Overall dimensions are approximately 21.5 inches deep × 20 inches wide × 14.4 inches high. The current U.S. configuration operates on 120 V, 50–60 Hz power and is rated at approximately 1,400 W and 12 A.
The supporting work surface should be stable, level, and capable of supporting the sterilizer plus process water, trays, and the maximum expected instrument load.
Adequate clearance should be maintained around the unit for ventilation, loading, door movement, maintenance, and service access.
Because the 2340M generates steam internally, a central building steam supply is not required. This makes it substantially easier to install than many large institutional sterilizers.
The reservoir drain valve is conveniently positioned at the front of the unit, simplifying routine water drainage.
Water quality should meet Tuttnauer's requirements. Inappropriate water can contribute to chamber scale, mineral accumulation, heater problems, valve contamination, and increased maintenance requirements over time.
Routine inspection and maintenance of the chamber, door gasket, safety systems, reservoir, heating components, and other wear items can help support reliable long-term operation.
