The Importance of Conductive Pipette Tips
Drug testing has become a common phenomenon. Sampling and liquid handling are the most common parts of the daily work in testing laboratories. Traditional manual operations carry a high possibility of human error. Liquid level detection is one of the key functions of automated liquid handling. How to accurately and sensitively detect liquid levels, thus avoiding the need to dip the pipette tip into the liquid, preventing liquid carryover, and achieving high-precision pipetting of very small volumes? Conductive pipette tips have emerged, and using these tips can enhance the sensitivity of diagnostic tests.
What is a conductive pipette tip?
A conductive pipette tip is a revolutionary development in the field of pipetting. These tips help to accurately transfer liquids in a static-free environment.
Conductive pipette tips are made from conductive materials that prevent static buildup, ensuring that samples are not affected by any static electricity.
Conductive pipette tips provide a good sealing pipetting experience and are compatible with various laboratory equipment, making them widely used in many types of laboratories.
The importance of conductive pipette tips
Conductive pipette tips play an important role in capacitive liquid level detection. When the tip comes into contact with the liquid, the potential precisely changes immediately, eliminating the need to immerse the tip in the liquid to aspirate. Thus, the risks of liquid carryover and cross-contamination are significantly reduced. Moreover, this method of liquid handling depends less on liquid level stability and simplifies the cumbersome programming requirements for pipetting positions.
Manufacturing requirements for conductive pipette tips
Conductive pipette tips generally require the use of pure PP combined with conductive materials and must be free of plasticizers and mold release agents;
The dimensional accuracy of conductive pipette tips must be high; otherwise, poor sealing consistency can result;
The inner wall should be smooth, free of flow marks, and the tip end should be free of nicks or burrs to ensure accurate dispensing;
Clean and free from biological contamination, requiring the conductive pipette tips to be manufactured in a super clean environment.
Advantages of conductive pipette tips
Low surface tension
High hydrophobicity
Enables capacitive liquid level sensing
Eliminates the effects of static electricity
These functions can minimize the risk of cross-contamination and reagent residue, ensuring the most precise and accurate pipetting.
