Characteristics and functions of 20μl pipette tips

1. Basic information

1. Capacity: 20μl (microliter)

2. Purpose: Mainly used for micro-liquid transfer in laboratories, and is a commonly used consumable in experiments in the fields of life sciences, medicine, chemistry and other fields.

2. Product features

1. High precision: The pipetting tips are precision designed and manufactured to ensure accuracy during the pipetting process.

2. Material: Mostly made of high-quality materials such as polypropylene (PP), which is resistant to chemical corrosion and high temperature.

3. Hydrophobicity: The surface of some tips has been treated with a special process to make it hydrophobic, which can significantly reduce the wetting phenomenon of liquids. 4. Reduce the loss of reagents and improve pipetting accuracy and precision.

4. Safety: No pyrogen, no endotoxin, no DNase, and no RNase to ensure the safety of the experiment.

5. Versatility: Applicable to mainstream pipettes on the market, such as Finland, Thermo Fisher, Dalong, Ebende and other brands.

3. Function

1. Precise pipetting

1>Micro-liquid handling: The 20μL pipette tip is particularly suitable for experimental scenarios that require precise handling of micro-liquids (such as a few microliters to tens of microliters). It ensures that the volume of liquid during pipetting is accurate, which is crucial for many scientific research and experiments.

2> Improve experimental accuracy: Since the design of the tip pays attention to details, such as smooth internal surface and fine tip, these features help reduce sample residue and improve the accuracy and precision of pipetting.

2. Protect samples and experimental environment

1>Avoid cross-contamination: Some 20μL pipette tips are equipped with a filter element design, which can effectively block aerosol contamination, thereby avoiding cross-contamination between samples. This is of great significance to maintain the accuracy and reliability of experimental results.

2>Safe sterilization: Many pipette tips will undergo irradiation sterilization during the production process to ensure their sterility. This helps protect samples from contamination while also providing a safer working environment for experimenters.

3. Wide applicability

1>Various materials and specifications: 20μL pipette tips are usually made of high-quality plastic materials (such as polypropylene PP), which meet relevant standards (such as USP Class VI) and can hold up under different experimental conditions Stablize. In addition, there are many specifications and models of pipette tips available on the market to meet the needs of different experiments.

2> Strong compatibility: 20μL pipette tips usually have good adaptability and can be used with various brands and models of micropipettes. This enables experimenters to conduct experimental operations more conveniently and improve work efficiency.

4. Application fields

1>Life sciences: In the fields of life sciences such as molecular biology and cell culture, 20μL pipette tips are widely used in the extraction, purification and analysis of nucleic acids such as DNA and RNA.

2>Medical research: In medical research fields such as drug screening and clinical testing, pipette tips also play an important role. They are used to accurately distribute liquid samples such as drugs and reagents to ensure the accuracy of experimental results.

3>Analytical Chemistry: In analytical chemistry, pipette tips are also commonly used to mix liquids or divide liquids into different containers, such as sample preparation in liquid chromatography analysis.

4. Product specifications and packaging

1. Specifications: Depending on the manufacturer, the specifications of the tip may vary, but their capacity and the applicable pipette model are usually clearly marked.

2. Packaging: Common packaging methods include bagging and boxing. Bags are generally 1,000 pieces/bag, 20 bags/box; boxes are mostly 96 pieces/box, 50 boxes/box. The specific packaging method must be based on the product manual or the information provided by the seller.

5. Brand and Price

1. There are many brands of 20μl pipette tips on the market, such as Jiete Biotech, Aisgen, Tecan, Keyend, etc. Prices vary depending on factors such as brand, material, packaging method and purchase quantity, ranging from a few yuan to dozens of yuan. The specific price needs to be determined based on market conditions and purchasing channels.

6. Purchase suggestions

1. Choose formal channels: It is recommended to purchase pipette tips through formal channels to ensure product quality and after-sales service.

2. Check the product description: Read the product manual carefully before purchasing to understand the product specifications, materials, packaging methods, scope of application and other information. Consider the experimental needs: Choose the appropriate pipette tip according to the specific needs of the experiment to ensure the smooth progress of the experiment.

The 20μl pipette tip is one of the indispensable consumables in the laboratory. Its accuracy, material, safety and versatility need to be paid attention to. When selecting and purchasing, multiple factors should be considered to ensure that experimental needs are met.
