sterile pipette tips used in the lab

Currently, there are three types of Pipette Tips: natural polypropylene and recycled polypropylene plastic (both of which should be transparent, odorless and chemically inert), or without additives. The quality of natural polypropylene is likely to be higher than that of recycled polypropylene plastic, but usually, additive color changing chemicals are added to black and yellow tips.
Three different aspects of cleanliness in Sterile Pipette Tips production can be considered. These are 2 Quality inspections to ensure that these raw materials are pure, each production process is selected.The machinery in the production workshop of a suction head must be at least 100,000 times cleaner than standard air.It's important to detect the Pipette tips for biological contamination before production. They need to have a certificate stating the detection data. If there is no data on the certificate or a non certified tip, it is not guaranteed to be free of contamination.
When it comes to sterile pipette tips, you need to be careful as they can become contaminated. As long as they come into contact with the air, there is a risk of biological contamination. You need to purchase boxed Pipette Tips if you have a stringent experiment.
Expert advice on lab advantage pipette tips
1. Maintain correct posture when pipetting; do not hold the pipette tightly at all times, use a pipette with finger hooks to help relieve hand fatigue; change hands frequently if possible.
2. Regularly check the sealing condition of the pipette. Once the seal is aging or leaking, the sealing ring must be replaced in time.
3. Correct the pipette 1-2 times a year (depending on the frequency of use).
4. For most pipettes, before use and after using for a period of time, apply a layer of lubricating oil to the piston to maintain tightness; and for Yongyue's conventional range pipettes, it is also ideal to not apply lubricating oil. of sealing.
