Pipette tips: Key tools for liquid transfer in the laboratory
发布时间:2025-11-19 10:35:08

Structure and Material

Structure: It is usually composed of the pipette tip body and the pipette tip plug. The pipette tip body is the part used for drawing up and releasing liquids, featuring an accurate tip design. The pipette tip stopper is used to connect the pipette tip body and the pipette, and it has sealing performance to prevent liquid leakage.

Material: It is mostly made of high-quality plastic materials, such as polypropylene (PP), which has good chemical inertness, corrosion resistance and certain elasticity. In addition, there are some special material pipette tips, such as those made of fluorinated ethylene-propylene copolymer (FEP), which have the advantages of all-scenario corrosion resistance, zero adhesion, and non-stickiness to walls. They are suitable for handling highly corrosive samples and experiments with extremely high precision requirements.

Type and Specification

By capacity classification: There are micro pipette tips and large capacity pipette tips. Micro pipette tips are suitable for the transfer of micro liquids, such as PCR reactions, etc. Large-capacity pipette tips are used in experiments such as cell culture that require the transfer of large amounts of liquid.

Classified by function: It includes ordinary pipette tips, filter pipette tips, etc. The filter tip is equipped with a built-in filter membrane, which can prevent impurities or microorganisms in the liquid being drawn from contaminating the pipette. It is often used in experiments such as bacterial culture. In addition, there are single-channel pipettes and multi-channel pipettes. Multi-channel pipettes can be used in conjunction with multi-channel pipettes to handle multiple samples simultaneously, thereby enhancing work efficiency.

Characteristics and Advantages

High accuracy: With precise design and manufacturing processes, it can ensure accurate liquid transfer and reduce experimental errors. For instance, the error of some high-quality pipette tips can be controlled within ±0.3%, and the repeatability deviation is < 0.2%.

lly has a drip-proof design to prevent liquid splashing and causing cross-contamination. Some pipette tips are also packaged aseptically and the material does not contain DNase, RNase, etc., making them suitable for experiments with high aseptic requirements.

Easy to use: Easy to replace and clean, convenient for laboratory operations. Pipette tips of different specifications can be applied to pipettes of different capacities, quickly meeting various experimental requirements.

Application field

Clinical testing: In clinical laboratories, it is often used for the transfer and distribution of biological samples such as serum, urine, and saliva, helping doctors accurately determine the patient's condition.

Drug research: It can be used for operations such as drug dilution, mixing and distribution, providing technical support for pharmacodynamic research and drug screening.

Cell culture: In cell culture experiments, it is necessary to precisely transfer cell culture medium, cell suspension, etc. Pipette tips can ensure the accuracy and sterility of the operation.
