Tuttnauer 2340M Autoclave Sterilizer

The Tuttnauer 2340M Autoclave is a high‑performance 19‑liter manual steam sterilizer engineered for fast turnaround, long‑term durability, and dependable daily operation. Designed for medical clinics, dental offices, laboratories, and surgical centers, the 2340M delivers consistent sterilization cycles with minimal maintenance—making it one of Tuttnauer’s most trusted models.

Built for efficiency, the 2340M features automatic shut‑off at the end of both sterilization and drying cycles, reducing staff workload and preventing overheating. Its bright, easy‑to‑use control panel is designed with the operator in mind, supporting quick cycle setup and reliable performance.

Safety is engineered into every detail. The unit includes a double safety locking device that prevents the door from opening under pressure and a dual safety thermostat for overheating protection. The front‑mounted drain valve allows fast, clean reservoir emptying—ideal for busy practices that require rapid cycle turnover.

With a 9" × 18" chamber and three stainless steel trays, the 2340M accommodates two full and two half cassettes, making it a strong fit for medium‑volume sterilization environments. Standard unwrapped cycle times include 12 minutes (hot start) and 20 minutes (cold start), supporting efficient daily workflows.

The electro‑polished chamber and door ensure long‑term corrosion resistance, extending the life of the autoclave and reducing maintenance costs. Backed by Tuttnauer’s 100‑year reputation in sterilization technology, the 2340M is a proven, reliable choice for facilities that demand performance and durability.

Comparison: Tuttnauer 2340M vs 2540M

1. Chamber Size & Capacity (The #1 Difference)

This is the deciding factor for most buyers.

Tuttnauer 2340M

• Chamber: 9" x 18"

• Ideal for:

  • Small medical offices

  • Single‑provider dental practices

  • Tattoo studios

  • Low–moderate daily sterilization volume

• Fits:

  • 2–3 cassettes

  • Small wrapped packs

  • Handpieces and basic instruments

Tuttnauer 2540M

• Chamber: 10" x 19"

• Ideal for:

  • Multi‑provider clinics

  • High‑volume dental practices

  • Urgent care centers

  • Surgical instrument turnover

• Fits:

  • 3–4 cassettes

  • Larger wrapped loads

  • More instruments per cycle

The 2540M gives you ~25% more usable space, which directly reduces the number of cycles needed per day.

2. Cycle Speed & Throughput

Both units use the same heating system and sterilization technology.

• Cycle times are similar, but the 2540M processes more instruments per cycle, making it effectively faster for busy practices.

• If you sterilize multiple loads per day, the 2540M saves time.

3. Footprint & Space Requirements

Both are countertop units, but:

• 2340M is slightly smaller and lighter

• 2540M requires a bit more counter depth

If space is tight, the 2340M may fit better.

4. Ease of Use

Both models offer:

• Analog pressure gauge

• Tuttnauer’s reliable mechanical design

There is no difference in usability — only in size and capacity.

Identical across both models:

• Stainless‑steel chamber

• Long‑life heating elements

• Low maintenance requirements

• Compatible with Tuttnauer Chamber Brite

Both are known to last 10–20+ years with proper care.
