Advanced Tube Sealing Solutions for Life Sciences: Sealed Reagent Chambers Without Compromise
Ensuring a reliable, contamination-free seal within a tube is a critical challenge in the life sciences industry, particularly for applications involving diagnostic reagents, research chemicals, or COVID-19 test kits. At Relco, we have developed an innovative induction sealing solution that creates sealed reagent chambers efficiently, safely, and without direct heat.
The Challenge: Precision Sealing in Tubes
Creating a sealed reagent chamber inside a tube requires addressing multiple technical constraints:
- Consistency: Every tube must have a perfect seal to prevent leaks or contamination.
- Speed: Production needs to meet high-volume demands without slowing workflow.
- Integrity: Sensitive reagents cannot be exposed to heat or contamination.
- Simplicity: The process must be operator-friendly to reduce errors and training time.
Traditional heat-based sealing methods risk damaging the inner tube surfaces or compromising reagents, making them unsuitable for many life sciences applications.
Our Solution: Adapted X/Y Punch and Induction Sealing Technology
Relco’s approach adapts our proven X/Y punch and seal machine, originally designed for COVID-19 test kits, to meet these stringent requirements. The process combines precision engineering with advanced induction sealing technology:
- Precise Reagent Delivery: A peristaltic pump with a diving nozzle deposits fluid accurately into the tube chamber.
- Foil Placement: The machine cuts foil to size, holds it with a vacuum, and positions it inside the tube on a secure ledge.
- Non-Contact Induction Sealing: The foil is sealed using induction technology, eliminating direct heat and preserving the pristine inner surfaces of the tube.
This method ensures that every tube is sealed flawlessly, protecting the integrity of sensitive reagents while maintaining high throughput.
High-Speed and Scalable Performance
- Single-head configuration: Seals 800–1000 tubes per hour, ideal for mid-volume production.
- Multi-head scalability: Can be expanded for larger operations, allowing flexibility for growing production demands.
