The Good
The Bad



Purchasing an autoclave sterilizer machine can look like a daunting task due to the wide array of products that are available in today’s market. Your buying journey doesn’t have to be all that complicated, as long as you stick to some basic rules. We’ve compiled some of the critical information you should consider when you’re in the market for an autoclave for sterilization and we hope that our guide assists you in making the right decision.

Technical factors

Before you even consider the size or number of trays or even the dimensions of the entire product, you ought to find out all there’s to know about it with regard to the maximum temperature it can achieve, source of steam it should use, pressure, contact, and the length of time in every cycle. Most of the convenient models we have seen feature operating cycles of about thirty to forty minutes and if ten minutes matter a lot for you and can significantly contribute to your lab’s productivity, that’s for you to tell.


Ease of use and convenience

These are two other factors to take into account as you need to find out if the autoclave sterilization process should be performed by an operator with a certain expertise in the field or it can be done by virtually anyone in the lab. While the operating basics of such a machine aren’t too complicated to figure out, it’s safe to say that some people might have more important things to do than spend twelve hours trying to understand the instruction manual.

One feature that relates both to safety and to convenience is whether or not the model comes with a manual control. If there’s a power failure, you or someone else in the lab should be able to complete an entire sterilization cycle just manually. This type of control should be located at hand and make it possible for the operator to stay safe at all times.


Construction quality

Both the chamber and the controls of the unit should have a particular thermal resistance that makes it impossible for them to be affected extreme temperatures. What’s more, several substances such as chlorides are commonly employed in various areas of medicine, which is why a medical autoclave sterilizer should have a chamber constructed out of nickel clad as this is virtually the only material that cannot be affected by these chemicals. Even stainless steel can be damaged by chlorides over time.

To make sure that you purchase the right product, we recommend checking for the ASME standards. This detail might be less important for models that just use dry heat and whose temperatures cannot exceed four hundred degrees Fahrenheit, for instance, but even these have to be in complete accordance with the requirements imposed by the ASME.

It is recommended that you get an electric autoclave sterilizer that comes with a microcomputer control that is not mounted over the door. This design can significantly increase the durability of the product as the controls will not be exposed to the heat or steam coming out of the autoclave.



Compact models can be very affordable but they strictly speak to the needs of professionals who require a limited number of pieces of equipment. Veterinarians and dentists can use this type especially as they can sterilize their instruments rather often, thanks to the many cycles they can perform in a day. That’s why they may not need the services of a large autoclave with many trays for multiple instruments. However, full-size professional alternatives can be bought for about four thousand dollars or more, depending on their capabilities and dimensions. Regardless of the one you will end up choosing, you ought to be aware of the fact that your research should involve reading some of the best autoclave sterilizer reviews as other buyers can give you pointers with regard to the potential mishaps you might experience.

The best autoclave sterilizers are showcased below. While these are all critically acclaimed units, we feel compelled to underline that they have different purposes and are intended for diverse applications.

In spite of the fact that it is both compact and lightweight, this unit uses wet heat to sterilize any items.
