Repeated epidemic, scientific research is not easy ~ nucleic acid detection is inseparable from pipette, a nucleic acid test does not say 100 times, at least dozens of pipette operations. The pipette, repeated suction is easy to produce aerosols (aerosol), if the sample is easy to adsorb residue, it is even more striking. RAININ offers high quality cartridge pipettes and low adsorption pipettes that match leading brand pipettes for precise pipetting and help us avoid aerosol contamination and sample attachment, preventing precious samples from being wasted.
The most effective method is to use a filter suction. This suction contains a filter element that protects the sample and protects the pipette from cross-contamination by aerosols, especially important in DNA amplification and sequencing:

But,
Why sometimes the use of filter cartridge suction may also lead to sample contamination!
Some suction manufacturers produce filter suction heads with a filter consisting of polyethylene and carboxymethyl cellulose that self-seals when the filter comes into contact with a liquid. However, the cellulose particles in the self-sealing filter can easily fall off and contaminate your sample, and may interfere with experiments such as PCR reactions.
RAININ's filter cartridge suction head is made of pure polyethylene, which is strong and does not break and fall off. The hydrophobic sintered particles prevent aerosols and liquids from being sucked into the pipette. The average pore size of the filter element is 40μm to prevent the passage of aerosols, but does not restrict airflow.
In addition, RAININ guarantees that the cartridge suction does not contain any cellulose particles or other additives that could contaminate you. For critical DNA or PCR experiments, the use of RAININ cartridge suction can give you peace of mind.
The most important purpose of using a filter cartridge is to prevent cross-contamination. When the pipette is in use, there is a risk of sucking liquid back. Therefore, in the process of using the same pipette to transfer different samples or reagents, the gun head with filter element needs to be used to avoid cross-contamination, which is also a point that must be paid attention to in the diagnosis of COVID-19.
The filter element is loaded by machine to ensure that the suction head is completely protected from damage during manufacturing and packaging. It was proved free of RNase, DNase, DNA and pyrogen contamination. In addition, all filter cartridges are pre-sterilized by radiation after packaging to prevent the risk of contamination of biological samples with bagged cartridges and damage to the filter cartridges through self-sterilization.
Rayning Research Grade Low adsorption universal head, less residue, low adhesion, high precision.
• The inner wall of the suction head is smoother, reducing liquid flow resistance and reducing sample residue.
• The inner wall of the super hydrophobic suction head allows the viscous liquid to coalescently and pass through the liquid with low surface tension, improving the accuracy of pipetting.
• Wide range of liquid applications for all water-based, viscous, foaming, precious liquids.
Low adsorption performance is excellent
• Prevent sample attachment, reduce sample residue and save valuable reagents.
• Improve experimental repeatability and achieve objectivity of data analysis.
• Suitable for aqueous liquids, viscous liquids, foaming liquids and precious reagents.
High quality clean suction head
