The pipette tip is an indispensable experimental instrument in biological research that a number of pipette tips are used in the experiment. The pipette tips of Servicebio are basically made of high quality low retention polypropylene plastic, which has the characteristics of colorless and transparent plastic with high chemical inertness and a wide temperature range.

Pipette tip is more accurate in releasing liquid in smaller quantities than burettes.
No matter which pipette tip you choose, low-retention is a key feature. Low-retention pipette tips retain low levels of liquid. Standard pipette tip will leave a little bit of liquid after dispensing. Low-retention pipette tips reduce this from happening due to hydrophobic plastic additive, keeping the liquid from sticking to the inside of the pipette tips.
Low retention pipette tips are particularly important in protein and nucleic acid research. Servicebio low retention pipette tips have the following features during experiment: reduce sample residue → improve accuracy and precision → improve sample recovery ）
Pipette tips are used with pipettes to reduce cross-contamination and speed processing.
Pipette tips are used to improve pipetting performance and pipetting results to ensure the purity of the liquid.
Pipette tips have "stuck points" that hold the pipette tips firmly and form a complete seal.
Pipette tip can be sealed after installation. No matter how much pressure is applied, it will not loosen.
Pipette tip can be firmly stuck on the pipettes with a light touch, completely eliminating the need for a strong impact to attach the pipette tip to the pipette.
There are two major designs of pipette tips, that are air displacement and positive displacement. A pipette tip will move liquid by pulling the liquid in, and then pushing it back out of the pipette. Pipette tips can be categorized by how they cause that displacement, and their applications can be different based on that technology.
The general principle of using a pipette tip is that the user will set a volume to aspirate and dispense. Liquid is pulled into an attached pipette tip, which is uniquely chosen for the volume being handled. These actions are controlled by a plunger and a piston. The more complex principle is the difference in how the piston is controlled and how it affects the liquid.
For most brands of pipettes, especially multi-channel pipettes, it is not easy to install the pipette tip. In order to pursue a good seal, you need to insert the pipette sleeve handle into the pipette tip. Turn it left and right, or shake it back and forth to tighten it forcefully. Some people also use the pipette to repeatedly hit the pipette tip to tighten, but this operation will cause the pipette tip to deform and affect the accuracy, and severely damage the pipette.
The operation of pipette tip should maintain a smooth and appropriate suction speed. If pipette speed is too fast, it will easily cause the sample to enter the sleeve, causing damage to the piston and sealing ring and cross-contamination of the sample.
