Pipette tips are disposable plastic tips used in conjunction with pipettes. They are used for accurately and precisely transferring small amounts of liquid and are key tools for liquid transfer in laboratories.

Materials and Properties

Material: Usually made of polypropylene (PP), it features excellent chemical stability, corrosion resistance and transparency, and is non-toxic, meeting laboratory safety requirements.

Features: Some pipette tips have undergone special treatment, such as being free of RNase, DNase, pyrogens, etc., which can prevent damage to biological samples

Dyeing; Some pipette tips also have low adsorption capacity, which can reduce the residue of samples on the inner wall of the tip and improve the accuracy of pipetting.

Types and Uses

Filter cartridge pipette tip: It is equipped with a filter cartridge inside, which can prevent liquid from being sucked back into the pipette and contaminating it. At the same time, it can also filter out impurities in the liquid. It is suitable for experiments with high requirements for sample purity, such as nucleic acid extraction and PCR experiments.

Low-adsorption pipette tips: Made of special materials or with surface treatment techniques, they reduce the adsorption force between the sample and the tip surface. They are suitable for transferring viscous liquids, protein solutions, nucleic acids and other easily adsorbed samples, which can reduce sample loss.

Wide-mouthed pipette tip: The tip has a larger diameter, which can reduce the shear force on fine samples and the flow resistance of high-viscosity samples. It is suitable for transferring samples sensitive to shear force, such as cell suspensions and genomic DNA.

Large-capacity pipette tips: The capacity is generally between 10mL and 20mL. With a special structural design, they can ensure a large sample capacity while maintaining the same precision as small-capacity tips, and are used for transferring large amounts of liquid.

Extended pipette tips: The tips are longer in length and can be inserted into deep and narrow containers for liquid aspiration and dispensing, such as centrifuge tubes and deep well plates, making it convenient to perform liquid transfer operations in special containers.

External piston pipette tip: Suitable for handling high-density, viscous and volatile samples, it is an intelligent solution for pipetting difficult-to-transfer liquids.
