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.

Our dedication to building successful partnerships is proven by the 2021 Net Promotor Score® of 70 among our diagnostics customers.

Electrically conductive PRE-ELEC® 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 plant operational in the U.S. in North Carolina by September 2025

A state-of-the-art compounding plant will secure a supply of critical diagnostics materials in the U.S.

In May 2022, the U.S. Department of Defense awarded Premix a contract to establish a plastic compound manufacturing plant in North Carolina’s Gaston County.

Premix’s work in building and keeping up resilient supply chains to secure global PCR testing throughout COVID-19 was rewarded. In the future, Premix’s locally produced specialty materials will secure a supply of critical diagnostic consumables in the United States.

The state-of-the-art facility will be fully operational in late 2025. It will allow Premix’s North American customers to enjoy local production and services, ensuring faster delivery speed and high reliability. The location has been chosen to best serve the growing region of advanced manufacturing in the southeastern U.S.


"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."
