Developing Programmable, Multi-Channel Filling Systems for DNA Sequencing Reagent Cartridges
Client Need & Project Overview
As automation continues to reshape the biotechnology industry, a leading DNA sequencing company sought to improve precision, flexibility, and traceability in its reagent cartridge manufacturing process. The client needed a programmable reagent cartridge filling system capable of supporting multiple tray geometries and recipes, along with a companion foil sealing station for the filled trays.
Both systems were designed for cleanroom operation, with trays manually loaded and unloaded by an operator. The solution required reliability, adaptability, and compatibility with the client’s manufacturing execution system (MES) for process monitoring and data capture.
NOVO Engineering developed custom filling and sealing equipment that addressed these challenges through integrated controls, configurable hardware, and intelligent feedback systems. This approach reflected the industry’s growing movement toward flexible, data-driven manufacturing in life sciences.
Key Engineering Challenges & Solutions
| Challenge | NOVO’s Solution |
|---|---|
| Precise Fill Volume Control Required accurate dispenses across a broad range of volumes, from large buffer fills to microliter-level reagent dosing. |
Implemented precision weighing as the primary feedback loop for volume control and added position feedback to modified peristaltic pumps as a secondary control. Developed a custom algorithm to adjust pump commands dynamically, compensating for variations in feed pressure and tubing wear. |
| Preventing Spills During Handling Cartridges were manually transferred between filling and sealing stations, increasing the risk of fluid movement. |
Refined cartridge geometry to minimize the potential for spillage during manual transfer, ensuring clean sealing surfaces and consistent product quality. |
| Quick, Intuitive Reconfiguration System changeover between tray layouts and fill recipes needed to be efficient and repeatable. |
Designed color-coded tubing, quick-connect fittings, and an intuitive software interface that simplified recipe setup and changeover between configurations. |
| Flexible Sealing System The sealing station required reliable and precise configuration for multiple tray geometries. |
Developed a modular nest system with adjustable parameters for time, temperature, and pressure, verified automatically by barcode detection of the tray type. |
Technical Innovations & System Design
NOVO’s multidisciplinary team combined mechanical design, control systems engineering, and custom software development to create a configurable and precise reagent handling platform.
- Closed-Loop Dispense Control: Combined gravimetric feedback and pump position data to maintain accurate fill volumes while conserving expensive reagents.
- Optimized Cartridge Geometry: Refined tray design to ensure stable handling and prevent liquid movement that could affect sealing performance.
- Fast, Repeatable Changeover: Color-coded connectors and user-guided software made it easy to switch between reagent types and tray formats.
- Barcode-Based Parameter Control: Automatically identified tray type and verified appropriate sealing settings for time, temperature, and pressure.
- MES Integration: Integrated NOVO’s application software into the client’s MES, logging all process parameters for traceability, optimization, and quality analysis.
This project represented an early example of how adaptive automation and process data integration can improve consistency and scalability in life sciences manufacturing, a capability that has since become central to the industry’s transition toward smart, connected production systems.
Results & Impact
- High Accuracy and Consistency: Maintained precise fill performance across a wide range of reagent and buffer volumes.
- Efficient Changeovers: Reduced setup and reconfiguration time through modular hardware and intuitive software guidance.
- Traceable Process Data: MES integration provided complete logging for every fill and seal cycle.
- Scalable Production: Following initial testing, the client ordered multiple additional systems with minor design variations.
