Staying Ahead of Innovation and Sustainability

Laboratory consumables were once made of glass. Today, they are primarily produced from petroleum-based plastics. These materials meet the strict quality standards required for advanced research. However, the demand for sustainable solutions is increasing.

At Hamilton, we prioritize both innovation and sustainability. We are actively developing eco-friendly consumables to reduce our CO₂ footprint. As part of this effort, Hamilton Bonaduz AG introduced the first-ever pipetting tips for automation made with 65% – 75% ISCC PLUS-certified polypropylene. This material comes from bio-circular feedstocks instead of fossil sources, following the mass balance approach.

How Did We Achieve This?

We launched GreenLine, our CO-RE II tip portfolio, which features 65% – 75% ISCC PLUS-certified bio-circular polypropylene.

  • During production, conventional and renewable raw materials are blended in a polymer reactor. A mass balance calculation determines the portion of ISCC PLUS-certified material.
  • The bio-circular polypropylene is fully traceable back to its first collection point. Each step in the supply chain undergoes strict monitoring and certification to ensure transparency.
  • This polypropylene holds the ISCC PLUS certification, the world’s leading standard for promoting a circular and sustainable bioeconomy.

What Is ISCC PLUS?

The International Sustainability and Carbon Certification (ISCC PLUS) supports the shift toward a circular and bio-based economy. This voluntary certification confirms the sustainability of alternative feedstocks throughout the supply chain, from origin to end consumer.

By choosing Hamilton’s GreenLine pipetting tips, laboratories can maintain high-quality standards while making a positive impact on the environment.
