High-Quality OEM Pipette Tips: Recognize These Key Points!

In the field of biological scientific research, pipetting operations are one of the basic steps, widely used in PCR experiments, gene expression analysis, antibody research, and cell culture projects. The success of the experiment often relies on precise pipetting operations, and the quality of pipette tips, as a key consumable, directly affects the experimental results. Therefore, choosing high-quality OEM pipette tips is particularly important. This article will introduce five key points to identify high-quality OEM pipette tips, helping you easily select the right product.

Material Selection of OEM Pipette Tips: Ensure High-Purity Polypropylene

High-quality OEM pipette tips are usually made of high-purity polypropylene (PP), which has excellent chemical inertness and can remain stable over a wide range of temperatures. Inferior tips often use recycled polypropylene materials, which may have chemical compatibility issues and even cause dissolution phenomena in experiments, contaminating reagents. To ensure the accuracy of the experiment, it is necessary to choose OEM pipette tips made of natural polypropylene, thus avoiding chemical reactions, contamination of pipettes, and samples.

Using low-quality materials not only affects experimental results but may also damage expensive pipettes and waste reagents. Therefore, when purchasing OEM pipette tips, material is the primary consideration.

Appearance and Concentricity of OEM Pipette Tips: Precision Design Ensures Stability

The appearance design is also extremely important for high-quality OEM pipette tips. Firstly, the surface should be smooth without burrs, flash edges, and should be uniformly shaped without bending or deformation. Observing the tip end under a microscope magnified 20 times, if the surface is smooth and burr-free, it indicates that the tip manufacturing process is excellent and of high quality. Such tips can ensure the accuracy of pipetting operations and reduce errors caused by tip defects.

In addition, attention should be paid to the concentricity of the tip. Place the tip bottom-down on a flat surface and observe from above. If the two circles formed by the tip are concentric, the concentricity is good. High concentricity OEM pipette tips can ensure the stability of the pipette during liquid aspiration, reducing liquid residue and errors. Precision design is a hallmark of high-quality tips and reflects the level of production craftsmanship.

Adsorption and Uniformity of OEM Pipette Tips: Reduce Pipetting Errors

The adsorption of the tip directly affects the precision of the experiment. High-quality OEM pipette tips should have low adsorption to ensure that the liquid does not cling to the wall or residue. If there is obvious liquid residue on the inner wall of the tip during actual operation, it indicates that the tip has high adsorption, which can easily cause pipetting errors. To ensure the precision of the experiment, you should choose low-adsorption tips to prevent liquid from staying during pipetting, ensuring accurate measurement of each aspirated volume.

Moreover, uniformity is also an important standard for measuring the quality of OEM pipette tips. Arrange multiple tips bottom-down closely on a table. If the spacing between the tips is uniform, it indicates that the size and shape of the tips are consistent and of stable quality. Tips with good uniformity can ensure consistency in multiple experiments, and will not affect the repeatability of experimental results due to quality issues.
