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
