Automatic gas tank switching system for CO2 incubators.

L F Liebes, V M Maher, P Scherr

|March 1, 1976

Summary

An automatic gas switching system ensures uninterrupted CO2 incubator function by monitoring pressure and switching to a reserve tank. An alarm alerts users to power or pressure issues, preventing incubator downtime.

Area of Science:

Biotechnology
Laboratory Equipment
Incubator Technology

Background:

Continuous monitoring of gas levels in CO2 incubators is crucial for maintaining optimal cell culture conditions.
Depletion of the primary gas supply can lead to incubator downtime and compromised experiments.
Manual intervention is often required to switch gas tanks, posing a risk of error or delay.

Purpose of the Study:

To describe the design and implementation of an automatic gas tank switching system for CO2 incubators.
To ensure a continuous supply of CO2 to the incubator, preventing experimental interruptions.
To provide an early warning system for potential gas supply or power failures.

Main Methods:

Development of a system that monitors gas pressure within the CO2 incubator's gas supply line.
Integration of an automatic switching mechanism to transition from a depleted main tank to a reserve tank.
Incorporation of an alarm system to signal critical events such as power loss or low gas pressure.

Main Results:

The system successfully monitored CO2 gas pressure and automatically switched to a reserve tank upon depletion of the main supply.
The alarm system effectively alerted users to power failures and critically low gas pressure.
Continuous CO2 supply was maintained, preventing potential disruptions to incubator function.

Conclusions:

The automatic gas tank switching system provides a reliable solution for maintaining uninterrupted CO2 supply in incubators.
This automation minimizes the risk of experimental failure due to gas supply interruptions.
The integrated alarm system enhances laboratory safety and operational efficiency.
