Choosing the right Tuttnauer autoclave starts with understanding how much instrument capacity your practice needs, whether manual or automatic operation better fits your workflow, and which sterilization cycles are appropriate for the instruments you process.

Tuttnauer offers tabletop steam sterilizers ranging from the lightweight T-Classic 9 to traditional manual autoclaves such as the 1730 Valueklave, 2340M and 2540M, advanced T-TOP Class S and Class B autoclaves, and the large-capacity 3870EAP.

This guide compares popular Tuttnauer autoclaves to help medical offices, dental practices, specialty clinics, veterinary practices and other healthcare facilities understand the differences and narrow down the right model.

Tuttnauer currently divides its tabletop lineup into manual and automatic sterilizers, with T-TOP models available in 21- and 27-liter configurations and the 3870EAP providing 85 liters of capacity.

T-TOP11S	27 L	Automatic Class S	Higher-capacity Class S
T-TOP11B	27 L	Automatic Class B	Higher-capacity Class B
3870EAP	85 L	Automatic	High-volume instrument processing

Tuttnauer currently specifies the 2340M at 19 liters, 2540M at 23 liters, T-TOP models at 21 or 27 liters, and 3870EAP at 85 liters.

Start With Capacity: What Size Tuttnauer Autoclave Do You Need?

Chamber capacity is an important starting point when comparing autoclaves, but the largest sterilizer isn't automatically the best choice.

Consider the number, dimensions and configuration of instruments normally processed in each load, how frequently your practice runs sterilization cycles, available countertop space, and whether instrument volume is likely to increase.

A smaller practice processing relatively light loads may not need the capacity of a T-TOP11 or 3870EAP. Conversely, a busy multi-provider facility may quickly outgrow a smaller chamber.

The goal is to choose enough capacity for your normal workflow without buying substantially more sterilizer than your facility needs.

Tuttnauer Manual vs. Automatic Autoclaves

One of the biggest decisions is whether to choose a manual or automatic Tuttnauer autoclave.

Tuttnauer Manual Autoclaves

Tuttnauer's traditional manual tabletop models include the 1730 Valueklave, 2340M and 2540M.

These models emphasize straightforward operation and proven tabletop steam sterilization. Tuttnauer currently positions the 2340M and 2540M for higher-volume clinics and laboratories, with 19- and 23-liter chambers respectively.

Manual models can be attractive for facilities that value simplicity and don't require the additional automation, connectivity and digital documentation available on newer sterilizer platforms.

Tuttnauer Automatic Autoclaves

Tuttnauer's automatic lineup includes the T-TOP Series and 3870EAP.

T-TOP models are available in 21-liter and 27-liter configurations and in Class S and Class B versions. The series also incorporates active closed-door drying.

Automatic sterilizers can reduce operator interaction with portions of the sterilization workflow and provide additional capabilities depending on the model.

Tuttnauer 1730 Valueklave: Traditional Simplicity

The Tuttnauer 1730 Valueklave is one of the manufacturer's established manual tabletop sterilizers.

Tuttnauer currently lists the Valueklave 1730 with an 18.9-liter chamber and three trays, positioning it as a value-oriented manual sterilizer.

The 1730 can be worth considering for practices that want straightforward manual steam sterilization and don't need the automation or digital features of the T-TOP platform.

Tuttnauer 2340M: A Popular Manual Tabletop Autoclave

The Tuttnauer 2340M provides a 19-liter chamber, three trays and capacity for two full and two half cassettes.

It is a strong traditional choice for facilities that want a manual tabletop autoclave with useful instrument capacity but don't require the larger chamber of the 2540M.

The 2340M is particularly worth comparing with the 2540M when choosing between Tuttnauer's established manual sterilizers.

Shop the Tuttnauer 2340M Autoclave

Tuttnauer 2540M: More Capacity in a Manual Autoclave

The Tuttnauer 2540M increases chamber capacity to 23 liters and provides four trays, compared with the 2340M's 19-liter chamber and three trays.

Tuttnauer lists capacity for up to three full and three half cassettes with the 2540M.

For facilities committed to a traditional manual autoclave but processing larger instrument loads, the 2540M can provide a useful step up in capacity.

Shop the Tuttnauer 2540M Autoclave

Tuttnauer 2340M vs. 2540M

These are two models many practices should compare directly.

Feature	Tuttnauer 2340M	Tuttnauer 2540M
Chamber Capacity	19 L	23 L
Trays	3	4
Full Cassette Capacity	2	3
Half Cassette Capacity	2	3
Operation	Manual	Manual
Primary Advantage	Smaller footprint/capacity	Greater load capacity

Both provide traditional manual operation. The decision primarily comes down to capacity and the size of the loads your practice expects to process.

Choose the 2340M when 19 liters and three trays adequately support your normal workload.

Choose the 2540M when the additional chamber volume, fourth tray and greater cassette capacity better match your instrument-processing needs.

Tuttnauer T-Classic 9: Compact & Portable

The Tuttnauer T-Classic 9 is unlike the other sterilizers in this comparison.

It has a 9-liter chamber, weighs only 11.7 lbs, accommodates instruments up to 9 inches long and offers unwrapped sterilization cycles starting at 18 minutes. One-touch operation starts the cycle through completion.

Tuttnauer specifically positions the T-Classic 9 for small clinics or as a backup autoclave in medium-to-large clinics.

Consider the T-Classic 9 when portability and compact size are more important than maximum instrument capacity.

Understanding the Tuttnauer T-TOP Series

The Tuttnauer T-TOP lineup provides a major step up in automation compared with traditional manual tabletop autoclaves.

There are four primary configurations:

T-TOP10S — 21 L Class S
T-TOP10B — 21 L Class B
T-TOP11S — 27 L Class S
T-TOP11B — 27 L Class B

Tuttnauer identifies the T-TOP series as automatic tabletop sterilizers available in 21- and 27-liter configurations, including Class S and Class B models.

This creates two decisions for buyers:

Do you need 21 L or 27 L?

and

Do you need Class S or Class B?

T-TOP10 vs. T-TOP11: Which Size?

The T-TOP10 platform provides a 21-liter chamber, while the T-TOP11 increases capacity to 27 liters.

The smaller T-TOP10 can make sense when 21 liters provides sufficient instrument capacity and conserving countertop space is important.

The T-TOP11 should be considered when a facility processes greater instrument volume or wants additional chamber capacity for future growth.

Rather than automatically selecting the larger model, consider your typical loads and how often the sterilizer is expected to operate.

T-TOP Class S vs. Class B

Capacity is only half of the T-TOP decision.

The other consideration is sterilizer class.

The T-TOP S models provide Class S cycles designed for load types specified by Tuttnauer.

The T-TOP B models add Class B pre-vacuum sterilization, providing advanced air removal for compatible load configurations where Class B processing is required.

The appropriate choice should be based on the instruments being processed, their manufacturer's instructions and your facility's sterilization requirements—not simply on the assumption that one class is universally “better.”

Tuttnauer T-TOP10S: Compact Automatic Class S

The T-TOP10S combines a 21-liter chamber with Class S sterilization, active closed-door drying, touchscreen operation and digital connectivity.

This model can be a good fit for facilities moving beyond a traditional manual autoclave but whose instruments and loads do not require Class B pre-vacuum processing.

Shop the Tuttnauer T-TOP10S Class S Autoclave

Tuttnauer T-TOP10B: Compact Class B Pre-Vacuum

The T-TOP10B uses the same 21-liter T-TOP10 platform but adds Class B pre-vacuum sterilization.

That makes the 10B particularly relevant for facilities that require advanced vacuum-assisted air removal while still preferring the smaller T-TOP chamber.

Shop the Tuttnauer T-TOP10B Class B Autoclave

Tuttnauer T-TOP11S: More Capacity With Class S Sterilization

The T-TOP11S increases chamber capacity to 27 liters while retaining Class S sterilization.

This can make it an attractive option for a growing or multi-provider practice that needs more instrument capacity but does not require Class B pre-vacuum capability.

The larger T-TOP11 platform also adds automatic water-management capabilities, helping reduce routine operator interaction.

Shop the Tuttnauer T-TOP11S Class S Autoclave

Tuttnauer T-TOP11B: Larger-Capacity Class B

The T-TOP11B combines the 27-liter T-TOP11 chamber with Class B pre-vacuum sterilization.

For facilities requiring both advanced Class B processing and greater chamber capacity, this is the model to compare directly against the smaller T-TOP10B.

Shop the Tuttnauer T-TOP11B Class B Autoclave

T-TOP10B vs. T-TOP11B

If you've already determined that Class B is required, the decision becomes much simpler:

T-TOP10B: 21 L — Class B with a smaller chamber.

T-TOP11B: 27 L — Class B with greater chamber capacity.

The T-TOP11 also offers additional water-management capabilities.

For lower-to-moderate instrument volume, the T-TOP10B may provide all the Class B capability required.

For busier practices, multiple providers or larger routine loads, the additional capacity of the T-TOP11B may be worth considering.

T-TOP10S vs. T-TOP11S

The same capacity question applies to the Class S models.

T-TOP10S: 21 L — smaller Class S configuration.

T-TOP11S: 27 L — larger Class S configuration.

If your facility's instruments can be appropriately processed using Class S cycles, there is no reason to choose a Class B unit solely because you want a larger chamber. The T-TOP11S provides the larger 27-liter platform in a Class S configuration.

Tuttnauer 3870EAP: When You Need Much More Capacity

The Tuttnauer 3870EAP is in a different capacity class from the T-TOP and traditional manual tabletop models.

It provides an 85-liter / 22-gallon chamber measuring approximately 15" × 30". Tuttnauer positions it for multi-practitioner practices, clinics and surgery centers and notes that its larger chamber can accommodate longer instruments or a large number of smaller instruments.

The 3870EAP also includes automatic operation, closed-door active drying, cycle monitoring and a built-in printer for cycle documentation.

Consider the 3870EAP when conventional tabletop sterilizer capacity has become a meaningful limitation.

Which Tuttnauer Autoclave Is Best for a Small Practice?

There isn't one correct model for every small practice.

For very small loads where portability matters, consider the T-Classic 9.

For facilities wanting traditional manual operation, compare the 1730 Valueklave and 2340M.

For practices that want greater automation and modern cycle documentation, consider the T-TOP10S or T-TOP10B, depending on required sterilization cycles.

Instrument type and load configuration should ultimately determine the appropriate sterilizer.

Which Tuttnauer Autoclave Is Best for a Busy Practice?

As instrument volume increases, chamber capacity and workflow automation become more important.

A facility that prefers traditional manual operation might consider the 2540M.

Practices looking for greater automation can compare the 27-liter T-TOP11S and T-TOP11B.

For instrument-processing volumes that substantially exceed conventional tabletop capacity, the 85-liter 3870EAP becomes worth considering.

Don't Forget Autoclave Cleaning & Maintenance

Choosing an autoclave is only part of maintaining an effective instrument-processing workflow.

Steam sterilizers require routine cleaning and maintenance according to the manufacturer's instructions.

Tuttnauer Chamber Brite is designed to clean and descale the chamber, reservoir and tubing of compatible steam sterilizers and remove hard-water deposits.

Always verify compatibility with your exact autoclave before using a cleaning product.

Water Requirements for Tuttnauer Autoclaves

Water quality is another important consideration.

For its traditional manual tabletop sterilizers, Tuttnauer instructs users to fill the reservoir with distilled water.

Follow the current operating manual for your exact model because water requirements and water-management systems vary between sterilizers.

Mohawk Medical Mall also offers Tuttnauer water distillers for facilities that want an on-site source of distilled water for compatible equipment.

How to Choose the Right Tuttnauer Autoclave

When comparing models, focus on five questions:

What instruments and load types are you sterilizing?
How much chamber capacity do you realistically need?
Do you prefer manual or automatic operation?
Do your instrument-processing requirements call for Class B pre-vacuum sterilization?
Would features such as closed-door drying, automatic water management and digital cycle documentation improve your workflow?

Answering those questions usually narrows the selection considerably.

For example, a facility wanting a straightforward manual sterilizer may quickly narrow its decision to the 2340M vs. 2540M.

A facility wanting automatic operation may instead focus on the T-TOP Series.

And a facility requiring Class B sterilization can narrow the T-TOP decision to the T-TOP10B vs. T-TOP11B, with capacity becoming a major differentiator.
