What is a pipette tip, what does a filter tip do?

The pipette is an indispensable experimental instrument in biological research, and the number of its accessories tips used in the experiment is also very large. Pipette tips on the market are basically made of polypropylene plastic (colorless and transparent plastic with high chemical inertness and wide temperature range). However, with polypropylene, the quality can vary greatly: high-quality tips are generally made of natural polypropylene, while low-cost tips are likely to use recycled polypropylene plastic (in this case, we can only Said its main ingredient is polypropylene).
In addition, most tips also add a small amount of additives during the manufacturing process, the common ones are:
1. Color material.
The blue tip (1000ul) and the yellow tip (200ul) commonly known in the market are the addition of corresponding color-developing materials to polypropylene (we hope it is high-quality masterbatch, not low-cost industrial pigments)
2 release agents.
Helps the tip break away from the mold quickly after forming. Of course, the more additives, the higher the chance of undesired chemical reactions during pipetting. So it is better not to add additives! However, due to the relatively high requirements on the production process, there are very few tips on the market that do not add additives at all.
Pipette Tip Specifications:
10ul/20ul/100ul/200ul/1000ul/1250ul
Because the tip filter is a disposable filter tip, the biggest role in 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 composed of Made of pure virgin sintered polyethylene. Hydrophobic polyethylene particles prevent aerosols and liquids from being drawn into the pipette.
The filter of the tip cartridge is machine loaded to ensure that the tip is completely unaffected during the manufacturing and packaging process. They are certified free of RNase, DNase, DNA and pyrogen contamination. Additionally, all filters are radiation pre-sterilized after packaging for enhanced protection of biological samples.
The use of filter tips can be used to prevent the pipette from being damaged by the sample, greatly improving the life of the pipette.
When to use a tip filter:
When to use the tip filter tip? Filter pipette tips must be used in all contamination-sensitive molecular biology applications. Filter tips help reduce the possibility of smoke formation and prevent aerosol contamination, thereby protecting the pipette shaft from cross-contamination. In addition, the filter barrier prevents sample carry-over from the pipette, preventing PCR contamination.
The filter tips also prevent the sample from entering the inside of the pipette during pipetting and damage the pipette.
Why is a tip filter necessary for virus detection?
The virus is contagious. If the filter tip is not used to isolate the virus in the sample during the virus detection process, the virus will be transmitted through the pipette;
Depending on the test samples, filter tips can be cross-contaminated with tissue samples during pipetting.
What is a pipette tip and the function of a filter tip? Let me introduce it to you first. If you want to know more about pipette tips, you can pay attention to Yongyue Medical and provide biological laboratory testing consumables. Welcome The majority of customers to inquire.
