Low-Cost CNC-Based media dispensing system for biotechnology laboratories

Area of Science:

• Plant Biotechnology
• Laboratory Automation
• Biotechnology Research

Background:

• Manual media dispensing in plant biotechnology research is labor-intensive and prone to variability.
• There is a need for automated solutions to improve efficiency, accuracy, and ergonomics in research laboratories.
• Existing automated systems can be prohibitively expensive for many research settings.

Purpose of the Study:

• To develop and implement a cost-effective Computer Numerical Control (CNC) based Automated Media Dispensing System (AMDS).
• To evaluate the performance of the AMDS against manual dispensing methods in a plant biotechnology research laboratory.
• To assess the system's potential for improving accuracy, efficiency, and ergonomics in media preparation.

Main Methods:

• Development of a dual-channel liquid dispensing system controlled by CNC.
• Two-year testing and refinement period for the Automated Media Dispensing System (AMDS).
• Performance evaluation including process capability index (Cpk) and time per tray efficiency.

Main Results:

• The AMDS achieved a process capability index (Cpk) of 2.28, significantly outperforming manual dispensing (Cpk of 1.43).
• The system maintained comparable time per tray efficiency to manual operations.
• Ergonomic benefits were observed, reducing prolonged standing for researchers.
• Estimated material cost is approximately 1/50th of comprehensive market solutions.

Conclusions:

• The developed CNC-based AMDS offers a significant improvement in media dispensing accuracy and consistency for plant biotechnology research.
• The system provides substantial ergonomic advantages and is a cost-effective alternative to existing automated solutions.
• Its modular design allows for future adaptations, promoting wider adoption of automation in research labs.
