Understanding the Different Types of Incubators for Your Research Lab: Air-Jacketed vs. Water-Jacketed
When it comes to choosing an incubator for your research lab, understanding the differences between air-jacketed and water-jacketed incubators is probably not all that important.
However, it might be.
Let’s compare:
Air-Jacketed Incubators
Function: Air-jacketed incubators use heated air to maintain the desired temperature inside the chamber.
Features:
- Rapid Temperature Recovery: Due to the nature of air as a heating medium, air-jacketed incubators often have faster temperature recovery times after the door is opened.
- Lower Maintenance: Air-jacketed systems typically require less maintenance compared to water-jacketed systems.
Applications:
- Ideal for applications requiring frequent access to the incubator.
- Labs with limited space, requiring a slightly more compact incubator
Pros:
- Quick Initial Temperature achievement
- Faster temperature recovery.
- Generally lower maintenance requirements.
- Lightweight and easier to move (Still pretty heavy though).
Cons:
- Can be less efficient in maintaining extremely stable temperatures compared to water-jacketed incubators.
- May consume more energy to maintain the desired temperature.
Water-Jacketed Incubators
Function: Water-jacketed incubators use heated water that surrounds the chamber to maintain a stable internal temperature.
Features:
- Stable Temperature Maintenance: The water jacket provides a better thermal buffer, leading to very stable temperature conditions inside the incubator.
- Extended Temperature Retention: In the event of a power outage, water-jacketed incubators retain their temperature for longer periods
- Uniform Temperature Distribution: Ensures that temperature fluctuations are minimized, providing a consistently controlled environment.
Applications:
- Ideal for applications requiring extremely stable and consistent temperature conditions, such as long-term cell culture experiments.
- Suitable for environments where power stability is a concern, as they can maintain temperature better during outages.
Pros:
- Superior temperature stability.
- Better temperature retention during power outages.
- Uniform heat distribution.
Cons:
- Slower temperature recovery compared to air-jacketed incubators.
- Higher maintenance due to the water system.
- Much Heavier and may require more space.
- ***Remember, when you purchase a water jacketed incubator it will ship EMPTY. You MUST remember to put water into the incubator before you run it. If not you may damage the heating element and get poor temperature stability.
Choosing the Right Incubator for Your Lab
Here are some key things that might sway you to one type of incubator or the other:
- Type of Research: For applications requiring frequent access, an air-jacketed incubator’s rapid recovery might be beneficial. For highly sensitive experiments, the stability of a water-jacketed incubator is preferable.
- Environmental Stability: If your lab experiences power fluctuations, a water-jacketed incubator will provide better protection for your samples.
- Maintenance Capabilities: Assess your lab’s capacity for regular maintenance. Water-jacketed incubators require more maintenance due to the water system.
- Space and Mobility: Air-jacketed incubators are generally lighter and more compact, making them easier to fit into limited spaces and move if necessary.
I always like having a table to compare things, so if you are someone who likes a table to compare/contrast things, here you go:

Conclusion
Both air and water jacketed will likely meet your needs and in many circumstances you won’t go wrong with either setup. However, there are reasons that there are two different kinds and if you were worried about getting the right one, hopefully this helped.
