What is a Laboratory Incubator Used For?

 

Laboratory incubators are imperative to maintaining environmental control. Essential for creating and sustaining precise temperature, humidity, airflow, and gas composition, Australian labs rely on incubators to run accurate, repeatable experiments.

From culturing cells and testing pharmaceuticals to fermenting food products, the right incubator can make all the difference. Learn about the different incubator uses in laboratory settings with our ultimate guide.

Laboratory Incubators 101

The incubator functions in a laboratory centre around ensuring stable conditions for samples to grow and behave as expected.

It generates and circulates heat inside an insulated chamber using resistive heaters while sensors monitor internal temperature and, where necessary, humidity and gas concentrations. Then, a microprocessor uses the feedback from these sensors to adjust and stabilise internal conditions continuously. This closed-loop control ensures minimal variability for consistent outcomes in sensitive research and production processes.

Whether for bacteria or enzyme cultivation, tissue culturing, or microbial testing, an incubator helps stabilise temperature (often between +25°C and +45°C). Depending on the model, units may include active humidity control, CO2 regulation, and fan-assisted airflow for even distribution.

At its core, it’s about ensuring a compliant and controlled workflow – cycle after cycle.

Common Incubator Types

Here’s a look at the most commonly used incubators and where they excel:

• Fluid Warming Cabinets & Chambers: Maintain IV fluids, blood products, and solutions at safe temperatures.
• Anhydric Incubators: For dry, stable incubation, ideal when humidity isn’t required.
• Refrigerated & Cooled Incubators: Perfect for reactions or tests that require sub-ambient conditions, such as food shelf-life studies or enzymatic reactions.
• CO2 Incubators: Maintain specific CO2 concentrations for optimal cell and tissue growth, used in growing mammalian and stem cells.
• Cycling Incubators: Automate temperature fluctuations to stress test stability or simulate conditions, essential for quality assurance and pharmaceutical stability trials.
• Shaking Incubators: Combine incubation with orbital shaking, supporting aerated cell or microbial cultures.
• Water-Jacketed Incubator: Provides extra temperature stability, which is especially helpful during frequent access.
• Portable Incubators: Compact, mobile solutions for on-site testing and transporting samples.
• General Purpose Incubators: Versatile and reliable for routine microbial work and sample storage.

Multi-Industry Applications: Key Incubator Uses in a Laboratory

Microbiology & Biotechnology

Critical for diagnostics, pharmaceutical development, and food safety testing, the incubator uses in microbiology include:

• Pathogen Identification: Provide an optimal temperature (often 35-37°C) for the growth and isolation of bacterial colonies from clinical, environmental, or pharmaceutical samples.
• Antimicrobial Susceptibility Testing: Repeatable environmental conditions ensure reliable comparison of microbial responses to various drugs or treatments.
• Sterility Assurance Testing: Quality assurance protocols in pharma production depend on incubators to monitor potential contamination.
• Enzyme & Metabolic Studies: Customised temperature and humidity profiles support advanced enzymatic pathway analyses.

Cell & Tissue Culture

• Create the optimal temperature and humidity needed for eukaryotic cell growth, critical in vaccine, antibody, and therapeutic production.
• Essential for cultivating mammalian, plant, and stem cells and supporting organoid development, drug screening, and regenerative medicine.

Molecular Biology

• Enable accurate incubation during PCR, hybridisation, and protein expression studies.
• Support nucleic acid amplification and enzyme reactions.

Pharmaceutical & Medical Research

• Ensure batch consistency and contamination prevention in drug and vaccine development.
• Used in sterility checks, drug testing, and shelf-life evaluation.

Food & Beverage and Industrial Use

• Fermentation studies in dairy, beer, and wine.
• Incubation for microbial contamination and HACCP testing.

Finding the Right Fit for Your Lab

When selecting an incubator for your facility, here are key factors to consider:

• Temperature Control: Does your application require precise thermal regulation within a narrow range?
• Variable Adjustments: Active control and sensors for humidity and CO2 manipulation.
• Volume & Footprint: Do you need a compact benchtop model or a high-capacity floor-standing unit?
• Airflow: Fan-forced circulation offers even temperature distribution, while natural convection is quieter and better for sensitive samples.
• Safety Features: Alarms, temperature cut-offs, and lockable doors are must-haves in regulated environments.
• Compliance & Data Logging: Built-in recording for QA, audits, or GMP compliance.
• Customisation: Custom builds offer a solution for complex research needs where off-the-shelf models cannot.
