In the context of precision medicine and high-throughput screening increasingly becoming the norm in scientific research and clinical experiments, the tip of a fully automatic pipetting workstation is a component that directly contacts the sample. Its quality and usage method have a decisive impact on the accuracy of experimental results. . This article will delve into the classification, characteristics, selection guide, usage precautions, and maintenance strategies of fully automated pipetting workstation tips.

1. Introduction to suction head types 1> Universal suction head: suitable for a wide range of liquid transfers, not targeted at specific types of liquids. 2> Sterile tips: Designed for experiments requiring aseptic operation to reduce the risk of sample contamination. 3> Filter tips: Used to avoid cross-contamination, especially when handling highly sensitive biological samples.

2. Analysis of suction tip characteristics 1> Material characteristics: Suction tips are usually made of polypropylene, which has good chemical stability and biocompatibility. 2> Design accuracy: High-precision tip design ensures the accuracy of each pipetting and reduces errors. 3> Volume range: Provide suction heads of different volumes to meet the liquid transfer needs of different volumes.

3. Tip selection method 1> Liquid characteristic matching: Select the corresponding tip according to the viscosity, corrosiveness and other characteristics of the liquid. 2> Workstation compatibility: Ensure that the selected tip matches the model and specifications of the fully automatic pipetting workstation. 3> Consider experimental needs: Choose the most appropriate tip type according to the specific needs of the experiment, such as throughput requirements, precision requirements, etc.

4. Suction head maintenance 1> Regular cleaning: After use, clean the suction head in time to avoid residues that are difficult to remove after drying. 2> Storage conditions: Store the tips in a dry, light-proof environment to extend their service life. 3> Replacement cycle: Set a reasonable replacement cycle based on frequency of use and experimental requirements to avoid using the same tip for a long time.

5. Precautions for using suction tips 1> Correct installation: Ensure that the suction tips are correctly installed on the pipetting workstation to avoid leakage or damage caused by improper installation. 2> Avoid excessive squeezing: During the pipetting process, avoid applying excessive pressure to the tip to avoid damaging the tip structure. 3> Pre-wet treatment: For some liquids, pre-wetting the tip can reduce adsorption and improve pipetting efficiency.

6. Suction heads and experimental efficiency 1> Improve experimental efficiency: Choosing the appropriate suction head can significantly improve the efficiency of the experiment and reduce manual operation time and labor intensity. 2> Reduce human errors: Automated pipetting reduces errors caused by human operations and ensures the consistency and reliability of experimental results.

7. Innovative applications of tips 1> Multi-channel tip technology: The new multi-channel tip allows processing of multiple samples at the same time, greatly improving the throughput and efficiency of experiments. 2> Special function tips: such as low-adsorption tips, heatable tips, etc., tips designed for specific experimental conditions to meet diverse experimental needs.

The correct selection and use of fully automated pipetting workstation tips is crucial to the accuracy and efficiency of experiments. By understanding the different tip types, characteristics, selection methods, usage considerations, and maintenance strategies, laboratory workers can use this tool more effectively. With the continuous innovation of technology, future tip designs will be more diversified and specialized to adapt to a wider range of experimental needs. Proper use and maintenance of pipette tips will help improve the quality and efficiency of experimental work and promote the progress of scientific research. At the same time, innovative tip technology will bring more possibilities to laboratory automation and provide stronger support for precision medicine and drug development and other fields.
