A CO₂ Incubator is a precision-controlled laboratory instrument designed to create and maintain optimal environmental conditions for cell culture and microbiological growth. It provides accurate regulation of temperature, carbon dioxide concentration, and relative humidity, which are essential for maintaining physiological conditions required by sensitive cell lines.
These incubators are widely used in cell biology, microbiology, molecular biology, immunology, genetics, oncology, IVF, and biotechnology laboratories.
What Is a CO₂ Incubator?
- A CO₂ incubator is used to grow and maintain living cells under conditions that closely mimic the human body. By maintaining:
- 37°C temperature
- 5% CO₂ concentration
- ~90% relative humidity
- the incubator ensures optimal pH balance in culture media and supports healthy cell proliferation.
- Air-jacketed CO₂ incubators use direct air heating to ensure fast temperature recovery and excellent uniformity, making them ideal for high-value and contamination-sensitive samples.
Key Advantages of CO₂ Incubators
- Rapid temperature and CO₂ recovery after door openings
- High stability for long-term cell culture experiments
- Reduced risk of contamination
- Uniform growth conditions across all shelves
- Ideal for difficult-to-grow and high-value cultures
