Reliable Liquid Level Detection Starts with the Right Material

Smart Material Solutions for Reliable Pipetting

In automated diagnostics, precise pipetting depends on reliable liquid level detection. PRE-ELEC® conductive plastics enable this by turning pipette tips into sensors allowing fast, accurate detection of liquid contact.

 

Capacitive Liquid Level Sensing – Enabled by Conductive Pipette Tips

In automated liquid handling systems, capacitive liquid level detection is the go-to method for ensuring accurate and reliable pipetting. This is where Premix’s PRE-ELEC® materials play a critical role.

By using pipette tips made from electrically conductive plastics, automated systems can detect the moment the tip touches the liquid — with no need to immerse the tip deep. This immediate response improves pipetting precision and reduces risks of:

  • Liquid carryover
  • Cross-contamination
  • Laborious reprogramming due to variable liquid levels

Why PRE-ELEC® Materials for Conductive Pipette Tips?

  Proven in Diagnostics
PRE-ELEC® compounds are widely used in high-precision diagnostic pipette tips across global healthcare markets, supporting millions of tests daily.
  Reliable Signal Transmission
Consistent electrical properties enable fast and accurate detection ofliquid level surface.
  Excellent Processability
Our compounds are designed for seamless integration into high-speed tip manufacturing, including thin-walled molding processes.
  Stable and Reproducible Quality
PRE-ELEC® materials meet the stringent requirements of the healthcare industry and deliver batch-to-batch consistency.
  Supporting Automation in Labs
As automation becomes the standard in modern laboratories, our materials help equipment manufacturers and component suppliers ensure flawless tip performance in robotic systems.
