Premix’s pipette tip materials have been recognized as the industry reference since the 1990s when the first liquid handling robots were launched. ​​

Since then, Premix has been developing material properties, production technology, and process capabilities in close cooperation with the diagnostics OEMs, liquid handling manufacturers, and medical molders.​​

During the COVID-19 pandemic, Premix ensured the rapid growth of global PCR testing through fast production scale-up and 100% supply accuracy of electrically conductive plastic, the key raw material of robotic automation pipette tips.

PRE-ELEC® electrically conductive plastic compounds comply with the high-quality standards and tight production tolerances of in vitro diagnostics and other lab analytics. Precision, purity, and consistency are the cornerstones of PRE-ELEC® compounds.

These mass-production-friendly materials enable faster cycle times and scaling up for higher cavitation tools up to 128 cavities. Their physical and chemical traits have been selected carefully to fulfill the requirements of each specific application they are intended for.​​

Electrically conductive pipette tips enable capacitive liquid level detection, which is the predominant technology in today’s automated liquid handling systems. The perfect pipette tip results from optimized production flow where the material, mold, and production technology work seamlessly together.

Electrically conductive pipette tips have various advantages:​

- Low surface tension​
- High hydrophobicity​
- Enables capacitive liquid level sensing​
- Eliminates the effect of static electricity​

These features minimize the risk of cross-contamination and reagent carryover and secure the most precise and accurate pipetting. Conductive pipette tips are essential in confirming reliable diagnostics in all circumstances.

New Premix plant in North Carolina

Our new plant in North Carolina doubles our production capacity, and our plants on two continents will improve our global supply and service. The state-of-the-art plant is designed to cater to the most demanding needs in healthcare and will secure critical diagnostics material supplies in the US as of September 2025. In late 2024, the plant will already start to offer toll compounding services and storage for compounds produced in Finland.

In May 2022, the US Department of Defense awarded Premix a contract to establish a plastic compound manufacturing plant in North Carolina’s Gaston County. Premix’s work building resilient supply chains to secure global PCR testing throughout COVID-19 was rewarded. As of 2022, we have had a local team managing the plant building and supporting our US customers.

With the new plant in the US, we can offer our customers better global supply capability, mitigate risks in global supply chains, and better serve our customers in the US market.

The facility will be fully operational in late 2025. It will allow Premix’s North American customers to utilize our local production and services, ensuring shorter lead times and high reliability. The location has been chosen to best serve the growing region of advanced manufacturing in the southeastern US.

In 2024, we will offer our current customers an option for local storage for compounds produced at our factory in Finland. In early 2025, we can do toll compounding in the plant, manufacturing our electrically conductive and dissipative range of plastic compounds for a wide range of applications where static electricity creates problems. 

Premix USA plant

"We are extremely excited about this opportunity to help secure a supply of critical diagnostic materials in the United States.

Our solutions meet strict standards for quality and cost-efficiency and provide valuable benefits to our new and existing customers."
