Mini Autoclaves: The Complete Guide to Compact Sterilisation for Clinics and Studios

If you’re short on space but still need reliable, compliant sterilisation, a mini autoclave could be the perfect solution. These compact units deliver the same Class B performance as larger models, but in a smaller footprint ideal for single-surgery practices, podiatry rooms, mobile practitioners, and tattoo or beauty studios.

At Excel Healthcare, the smallest and most portable sterilisation options are the Elite 3 Litre B, the Enigma 8 Litre B, and the New Generation 8 Litre B. Each model is designed to offer full vacuum sterilisation, fast cycles, and easy operation while taking up minimal bench space.

This guide answers common questions such as “What is a mini autoclave?”, “Which small autoclave is best?”, and “Can a compact autoclave still pass compliance checks?” — all with the aim of helping you choose the right machine for your environment.

What Is a Mini Autoclave?

A mini autoclave is a compact Class B steriliser with a chamber size typically between 3 and 8 litres. Although smaller than full-size 17L or 22L units, they use the same vacuum-assisted steam process to sterilise hollow, wrapped, and solid instruments.

This makes mini autoclaves suitable for:

• Single-chair dental surgeries

• Podiatry and chiropody clinics

• Tattoo and piercing studios

• Beauty and aesthetics rooms

• Mobile practitioners

• Training centres or low-volume sterilisation setups

These units offer a balance of portability, speed, and full compliance with UK sterilisation standards such as BS EN 13060 and HTM 01-05.

Why Choose a Mini Autoclave?

Mini autoclaves are designed for professionals who need:

• A smaller sterilisation load

• Fast cycle times

• Limited bench space

• Lower running costs

• Easy installation

• Reliable Class B vacuum sterilisation

Despite their size, these compact models provide the same level of sterilisation performance as their larger counterparts.

Common Questions About Mini Autoclaves

Do mini autoclaves work the same as full-size models?
Yes. Class B mini autoclaves use the same vacuum and steam technology as larger units.

Not at all — they are ideal for practitioners who sterilise small sets or work with fewer instruments per cycle.

How long are the cycles on a mini autoclave?
The Elite 3L can complete some cycles in under 11 minutes. 8L models typically range from 15–30 minutes depending on load and wrapping.

Can I use mini autoclaves with sterilisation pouches?
Yes — they work seamlessly with self-seal sterilisation pouches.

Are mini autoclaves cheaper to run?
Yes, they use less water, power, and reduce overall wear due to smaller loads.
