What Is a Bacteriological Incubator?
A bacteriological incubator is designed to maintain a stable temperature—typically from 5°C above ambient to around 60°C—to promote bacterial growth. These incubators use basic heating systems and simple controls, making them easy to operate and maintain.
Common Uses:
- Microbiology and pathology laboratories
- Diagnostic centers
- Educational and teaching laboratories
Because of their straightforward design, bacteriological incubators are widely used for routine incubation tasks.
What Is a Modern Digital Incubator?
A modern digital incubator uses microprocessor-based control systems to regulate temperature with high accuracy. Most models feature digital displays, programmable settings, alarms, and sometimes data logging capabilities. These features allow better monitoring and consistency during incubation.
Common Uses:
- Biotechnology and pharmaceutical research
- R&D laboratories
- Regulated environments requiring documentation
