How to select a laboratory incubator: key considerations for evaluating performance metrics
Laboratory incubators are often one of the unsung heroes in scientific research, playing a vital role in cell culture and ensuring consistent experimental in vitro conditions. When selecting an incubator, understanding instrument performance is paramount, as your decision can impact the reliability, reproducibility, and integrity of your work. However, evaluating performance claims and determining how well an incubator will function in your specific lab environment can be challenging.
Key strategies for assessing laboratory incubator performance, include:
- Evaluating critical performance metrics and their relevance to your needs
- Understanding the complexities of contamination control assessment
- Bridging the gap between manufacturer data and real-world usage
By gaining insights into these areas, you can make more informed decisions when selecting an incubator that aligns with your research requirements.

Understanding key laboratory incubator performance metrics
When evaluating incubators, several key performance metrics can significantly impact the consistency and reliability of your experiments. These metrics include:
- Temperature, CO2, and humidity uniformity: The ability to maintain consistent conditions across the entire incubator chamber.
- Temperature, CO2, and humidity accuracy: How well the incubator maintains set environmental conditions over time.
- Recovery after door opening: The speed at which the incubator returns to set conditions following a door opening.
Strong performance in these metrics indicates an incubator's ability to maintain sample integrity and support experimental reproducibility. However, understanding performance claims and determining their relevance to your specific application can be tricky.
When reviewing performance data, ensure you have a clear picture of the testing conditions, how these might influence results, and how relevant these are to your intended use. Make sure you know key testing parameters, such as:
- Ambient temperature/humidity
- Probe placement
- Door opening speed/duration
- Traffic in the testing space
By critically evaluating these aspects, you can better assess how an incubator's stated performance might translate to your specific laboratory environment and experimental needs.
Evaluating contamination control in laboratory incubators
Contamination in cell cultures can severely disrupt experiments and impede laboratory productivity. Laboratory incubators with effective contamination control features can help minimize this risk, but how can you assess contamination control performance?
Similarly to other performance metrics, the main challenge in understanding and comparing the quality of contamination control features is differences in testing conditions. Variation across equipment providers is usually introduced through:
- The chosen contaminant
- Contaminant concentration and introduction
- Decontamination control method
These variations can significantly impact test results, making it difficult to interpret how well an incubator's contamination control features will perform in your specific laboratory environment.

Bridging the gap between performance data and real-world use
When evaluating laboratory incubators, it's crucial to contextualize equipment provider performance data within your specific laboratory environment. To make an informed decision, consider the following strategies:
- Gather real-world insights: Reach out to end-users within your company, repair technicians, and facilities personnel. Their practical experiences can provide valuable perspectives on an incubator's performance in settings similar to yours.
- Consider long-term performance: While short-term data is useful, it may not reflect an incubator's reliability over time. Seek out long-term user testimonials or request customized testing that simulates prolonged usage in your specific application.
- Look beyond manufacturer claims: Explore independent reviews and peer feedback from other scientists who have used the equipment. This can offer unbiased insights into how different models perform in real-world settings.
By applying these strategies, you can better interpret performance data and choose an incubator that truly meets your lab's unique needs and supports your research goals.
