Optimising tube automation for maximum sample recovery

Nov 20 2023

Azenta Life Sciences has unveiled its ground-breaking tri-coded 1.6ml Maximum Recovery tube, specifically designed for automated liquid handling workflows. The tube's distinctive shape at the bottom enhances sample retrieval, making it ideal for efficient and precise automated processes.

Addressing the challenge of large dead volumes in storage tubes, particularly crucial for handling precious samples such as stem cells and enzymes, Azenta Life Sciences emphasises the limitations of manual pipetting in high-throughput labs relying on automated liquid handling systems.

To optimise sample recovery, Azenta's research underscores the importance of addressing factors contributing to dead volume in storage tubes. The incorporation of internal compound-curve tapers near the bottom of the tube is identified as a key design element. This innovation reduces the total volume stored in the critical area while maintaining accessibility for industry-standard pipette tips.

Comparative research between the new 1.6ml Maximum Recovery tube and standard 1.9ml tubes reveals a substantial advantage. Over a run of 100 tubes, the 1.6ml Maximum Recovery tube recovers an additional 16ml. This improvement translates into significant cost savings, especially with expensive reagents or valuable samples.

Beyond maximising sample recovery, the unique design of the 1.6ml Maximum Recovery tube aligns with sustainable practices, offering users an opportunity to reduce reagent purchasing costs and contribute to environmentally conscious lab workflows throughout the supply chain.
