The selection of pipette tips is crucial for the accuracy and efficiency of experiments. Here are some recommendations for choosing pipette tips:

1. Material:

• Polypropylene Plastic: Most pipette tips are made of polypropylene plastic, known for its chemical inertness and wide temperature range. Ensure the selection of high-quality tips, preferably made from natural polypropylene, to ensure experiment accuracy.
• Additives: Some tips may contain colorants or mold release agents. Choose tips with high-quality additives and avoid excessive use of additives to reduce the risk of unwanted chemical reactions during pipetting.

2. Packaging:

• Bagged and Boxed: Pipette tips are commonly packaged in bags or boxes. Boxed packaging is more common in mature markets, while bagged packaging is prevalent in some regions. Note that bagged tips may increase the risk of contamination, while bulk-packaged tips are an environmentally friendly option.

3. Price:

• Grade Selection: Pipette tips are typically categorized into imported tips, domestically produced tips under imported brands, and domestically produced tips. Understand the performance and application scenarios of different grades, and choose tips that suit your experimental needs.
• Boxed and Bulk-Packaged: Boxed tips are usually priced at 1.5-2.5 times the cost of bagged tips, while bulk-packaged tips may offer a more economical choice.

4. Special Tips:

• Application-Specific: Consider specialized tips designed for specific samples or applications, such as gel-loading tips, wide-mouth tips, low-retention tips, extended tips, or external-piston tips.

5. Compatibility:

• Brand and Model: Different brands and models of pipettes may require specific tips. Ensure that the selected tips are compatible with the pipette being used for optimal performance and accuracy.
• Volume Range Compatibility: Ensure that the tip's volume is suitable for the pipette's maximum range to avoid mismatch-related issues.

6. Purchase Recommendations:

• Inform the Supplier: When purchasing tips, provide the supplier with the tip model or at least the brand and volume range of the pipette being used to ensure compatibility.

Considering these factors will help in choosing pipette tips that meet the specific requirements of your experiments, enhancing accuracy and efficiency.
