What is a pipette tip and the function of a filter tip?
Pipette tips Yongyue Medical supplies: pet indwelling needles, fluorescent quantitative PCR consumables, pipette nozzles, microcentrifuge tubes, imported cryopreservation tubes, cell culture dishes, culture plates, culture bottles, imported tips, instruments and Gloves, chromatography consumables, syringe filters, etc.
The pipette is an experimental instrument in biological research, and the number of its accessory tips in the experiment is also very large. The tips on the market are basically made of polypropylene plastic (colorless and transparent plastic with high chemical inertness and a wide temperature range). However, the quality of the same polypropylene will vary greatly: high-quality tips are generally made of natural polypropylene, while cheap tips are likely to use recycled polypropylene plastic (in this case, we can Said its main component is polypropylene).
In addition, most of the tips will add a small amount of additives during the manufacturing process, the common ones are:
1. Color-developing material.
The commonly known blue tip (1000ul) and yellow tip (200ul) in the market are the addition of corresponding color-developing materials to polypropylene (we hope it is a high-quality masterbatch, not cheap industrial pigments)
2. Release agent.
helps the tip to be separated from the mold quickly after forming. Of course, the more additives, the higher the probability of undesirable chemical reactions during pipetting. So fortunately, no additives are added! However, due to the relatively high requirements for the production process, nozzles that do not add additives at all are rare in the market.
Pipette tip specifications:
10ul/20ul/100ul/200ul/1000ul
The role of the tip filter:
Because the tip filter element is a secondary filter tip, its major function during use is to prevent cross-contamination: Unlike other filter types that contain additives that can inhibit enzymatic reactions, the filtered pipette tips supplied by Bunsen are made of Made of pure virgin sintered polyethylene. Hydrophobic polyethylene particles prevent aerosols and liquids from being sucked into the pipette body.
The filter of the tip filter element is machine-loaded to ensure that it is completely unaffected during the manufacturing and packaging process. They are certified to be free of RNase, DNase, DNA and pyrogen contamination. In addition, all filters are pre-sterilized by radiation after packaging to enhance the protection of biological samples.
The use of filter tips can be used to prevent the pipette from being damaged by the sample and greatly increase the service life of the pipette.
When to use the tip filter:
When to use the tip filter tip? Filtered pipette tips must be used in all molecular biology applications that are sensitive to contamination. The filter tip helps reduce the possibility of smoke formation, prevents aerosol contamination, and thus protects the pipette shaft from cross-contamination. In addition, the filter barrier prevents the sample from being carried away from the pipette, thereby preventing PCR contamination.
The filter tip also prevents the sample from entering the pipette and causing damage to the pipette during pipetting.
Why a suction tip filter must be used to detect the virus?
The virus is contagious. If the filter tip is not used to isolate the virus in the sample during the virus detection process, it will cause the virus to be transmitted through the pipette;
The difference between the test samples, the filter tip can organize the cross-contamination of the sample during the pipetting process.
What is a pipette tip and what is the function of a filter tip? I will first introduce you to this. If you want to know more information about pipette tips, you can pay attention to Yongyue Medical and provide it to IVD biomedical customers. For biological laboratory testing consumables, customers are welcome to inquire.
