What are the characteristics of the pipette tip filter and what is its function?
The filter element of the pipette tip is made of ultra-pure imported polyethylene raw material, which has strong hydrophobicity, which can perfectly block the aerosol and avoid the contamination of the inside of the pipette gun caused by fluid and liquid vapor.
Features:
(1) The tip is made of medical grade polypropylene, and the filter element is made of ultra-high molecular weight polyethylene, which has good hydrophobicity
(2) The filter element effectively forms a protective structure between the pipette and the sample to ensure the safety of the sample; it reduces the harm of the gas residue in the gun body to the operator during the pipetting process, and improves the repeatability of the experiment
(3), provide low adsorption and ordinary filter tips, no coating design, will not contaminate the sample, the surface of the low adsorption tip is completely hydrophobic;
(4), can be sterilized by high temperature and high pressure
(5), provide sterile rack and ordinary bulk
Why are only sterile pipette tips used in the lab?
Personnel safety guarantee: reduce the spread of harmful samples and protect the health of operators.
Sample safety assurance: prevent cross-contamination between samples and contamination of impurities inside the pipette, ensure that samples meet the requirements of subsequent experiments (no DNase/RNase, no PCR inhibitors, etc.), and minimize sample loss.
Equipment safety guarantee: avoid liquid overshoot into the pipette cavity, maintain the precision and accuracy of pipetting, and prolong the service life of the pipette.
application:
Handling demanding molecular biology samples such as PCR samples
Handling radioactive, biotoxic, corrosive, volatile and other dangerous samples
Pipette tips for installation of pipettes
For most brands of pipettes, especially multi-channel pipettes, it is not easy to install the tip: in order to pursue a good seal, it is necessary to insert the pipette handle into the tip and turn it left and right or back and forth to tighten it. . Some people also use the pipette to repeatedly hit the tip to tighten, but this operation will cause the tip to deform and affect the accuracy, and in severe cases, the pipette will be damaged, so such an operation should be avoided.
