Fitting on the end of a pipette and creating an air-tight seal as well, Hawach’s high quality graduated pipette tips can always fulfill the pipetting needs of your research, diagnostics, and analytical laboratories. The pipette tips play a significant role in the results of an experiment, as they contact the samples directly. It’s also a great help to prevent cross-contamination when you discard the tips between each experimental step.
Made from non-sterile PP material and compatible with almost all the popular brand’s pipettes, Hawach’s pipette tips are made for one-time use with a volume ranging from 10ul to 10ml.
Hawach’s pipette tips are designed for use in a wide variety of pipetting applications and manufactured in the ultra-clean room for contamination-free product. They guarantee not only accurate pipetting with the perfect airtight grip on the pipette by inner radial rings, but perfect sealing and no leaking with the design of flexible and soft tip cone. You can find that the clean hydrophobic surface of Hawach’s pipette tips ensures not only low retention but increased accuracy and reproducibility at the same time.
Installation of Pipette Tip
In order to better install the pipette tip, there are some tips you can refer to In the process of pipetting liquid, the downward pressure of the thumb must be slowly reduced to make the liquid rise evenly and slowly in the pipette tip.
After the bottom end of the pipette handle enters the tip, if you operate in the tip box, gently press down while shaking the pipette left and right or slightly rotating the pipette (only single-channel pipettes can rotate) 1-2 seconds is enough; if you are using bulk tips, turn the tip slightly for 1-2 seconds while gently applying pressure to the pipette. If this operation fails to achieve the desired seal, you need to check the tip and pipette.
Depth and Angle of aspiration in Pipette Controls
(1) Requirements for the immersion depth of the pipette tip: The depth of aspiration must ensure that the required pipette volume is reached; The pipette keeps the outer wall of the tip in contact with the liquid as little as possible. (2) The angle of the pipette: the pipette must always be kept upright during the process of pipetting.
