How do Filtered Pipette Tips help solve the problem of bubbles in micro-liquid transfer?

In daily laboratory operations, micro-liquid transfer is an extremely common and critical task. However, the bubble problem often troubles experimenters, affecting the accuracy and repeatability of experimental results. Fortunately, Filtered Pipette Tips play an important role in solving the bubble problem in micro-liquid transfer.
1. The generation and impact of bubble problems
When transferring micro-liquids, bubbles may be generated from multiple aspects. First, improper operation of the pipette may introduce bubbles. For example, too fast aspiration speed, too deep or too shallow insertion of the pipette tip into the liquid surface may cause air to mix into the liquid. Second, the properties of the liquid itself may also cause the formation of bubbles. Some liquids with surface activity or under temperature changes are prone to bubbles.
The presence of bubbles has a serious impact on experimental results. In micro-analysis experiments, bubbles may occupy a certain volume, resulting in inaccurate actual amount of liquid aspirated. In molecular biology experiments, bubbles may interfere with enzymatic reactions, PCR and other processes, affecting the success rate of the experiment. In addition, bubbles may burst in subsequent experimental steps, causing liquid splashing and contaminating the experimental environment.
2. Unique design of Filtered Pipette Tips
Filtered Pipette Tips usually adopt a special design to help solve the bubble problem. Its main features include:
Filter membrane structure
The filter membrane inside the filter tip can not only block impurities and contaminants, but also play a certain buffering role. When the liquid passes through the filter membrane, the flow rate will be appropriately slowed down, which helps to reduce the generation of bubbles. At the same time, the filter membrane can intercept the already formed tiny bubbles inside the tip to prevent them from entering the pipette.
Optimized internal shape
The internal shape of the Filtered Pipette Tip is carefully designed to reduce turbulence and eddy currents during the flow of liquid. This optimized shape allows the liquid to flow more smoothly and reduces the possibility of bubble formation. For example, some filter tips adopt a conical design, which makes the liquid flow more smoothly in the tip.
High-quality materials
High-quality filter tips are usually made of high-quality materials such as polypropylene. These materials have good chemical stability and low surface tension, which can reduce the adhesion between the liquid and the inner wall of the tip, thereby reducing the generation of bubbles.
3. Usage and precautions of Filtered Pipette Tips
In order to give full play to the role of Filtered Pipette Tips in solving bubble problems, the correct usage and precautions are also very important.
Choose the right specifications
Choose filter tips of appropriate specifications according to experimental requirements. Tips of different specifications are suitable for different liquid volumes and pipette models. Choosing the right tip can ensure good sealing and liquid flow performance and reduce the generation of bubbles.
Correct operating skills
When using pipettes and filter tips for liquid transfer, you should maintain smooth operation. When aspirating, you should slowly and evenly lift the button of the pipette to avoid aspirating too fast. When inserting the tip, you should ensure that the tip is inserted vertically into the liquid surface with a moderate depth. When discharging liquid, you should also press the button of the pipette slowly and evenly to avoid liquid splashing and bubble generation.
Regular inspection and replacement
Regularly check the status of the filter tip, and replace it in time if it is damaged or contaminated. Blockage or damage of the filter membrane may affect its filtering effect and bubble interception ability. At the same time, the tip used for a long time may deform and affect the accuracy of the experimental results.
