How to choose laboratory pipette tips?

Classification of pipette tips

As a consumable used in conjunction with pipettes, tips can generally be divided into: standard tips, filter tips, low adsorption tips, automatic workstation tips, and wide-mouth tips according to different applications.

1. Standard tips are the most widely used tips, and common tips can be used for almost all pipetting operations, which is the most economical type of tips.
2. The filter tip is a consumable designed to avoid cross-contamination. The sample taken by the filter tip cannot enter the inside of the pipette, so as to protect the parts of the pipette from contamination and corrosion, which is more important. It can also ensure that there will be no cross-contamination between samples, and is often used in experiments such as molecular biology, cytology, and virology.

3. For experiments with high sensitivity requirements, or precious samples or reagents that are easy to remain, you can choose low-adsorption tips to improve recovery. There are more residues.

The packaging specifications of the tip are mainly bagged and boxed. The boxed ones are sterilized at the factory and can be used directly by the user; the bagged tips are 500 or 1000 per bag, and most users will buy the bagged tips and then put the tips into the tip box. . Boxes are relatively expensive, but bags also increase the risk of contamination during manual loading of tip boxes.
