Bunsen teaches you how to properly select cartridge tips versus regular tips?

Keywords: Filter tips BUNSEN Pipette universal standard tips Bunsen teaches you how to correctly choose filter tips and conventional tips? Filter tips because they are disposable filter tips, the biggest role in the use of the process is to prevent cross-contamination, unlike other types of filters that contain additives that inhibit enzymatic reactions, biological tissue filtered pipette tips are made
of pure, original sintered polyethylene.
Hydrophobic polyethylene particles prevent aerosols and liquids from being sucked into the pipette
.
The filter of the cartridge tip is machine-loaded to ensure complete unaffected
during manufacturing and packaging.
They are certified to be free of RNase, DNase, DNA and pyrogen contamination
.
In addition, all filters are radiated pre-sterilized after packaging to enhance the protection
of biological samples.
The use of filter tips can be used to prevent pipette from being damaged by the sample, greatly increasing the service life
of the pipette.
Filter tips and conventional tips common announcements: pipette universal standard tips have 6 specifications: 1, 10ul (0.
5-10ul white short tip, 0.
5-10ul white long tip); 2, 20ul (0.
5-20ul white long tip); 3, 100ul (10-100ul yellow); 4, 200ul (20-200ul yellow); 5, 1000ul (100-1000ul blue); 6, 5000ul (1000-5000ul white); How to choose pipette tips: First, the material At present, the tips on the market are basically made
of polypropylene plastic (colorless transparent plastic with high chemical inertia and wide temperature range).
However, the same polypropylene, the quality difference will be very large: 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 say that the main ingredient is polypropylene).

In addition, most tips will also add a small amount of additives in the manufacturing process, common are: 1, color rendering materials
.
In the market commonly known as blue gun head (1000ul) and yellow gun head (200ul), is in the polypropylene added the corresponding color rendering material 2, the release agent
.
Helps the tip to detach from
the mold quickly after forming.
Of course, the more additives, the higher
the probability of unwanted chemical reactions occurring during pipetting.
Second, the packaging of the tip is mainly in the form of bags and boxes
.
In a relatively mature market, boxed is the majority; In China, bagging is currently the mainstream—mainly because bags are cheap
.
The so-called bagging is to put the suction heads in a plastic self-sealing bag, 500 or 1000 per bag (the number of large range tips per bag will be much less).

Most users will buy a bag of tips and then manually put them into the
tip box.
Although China's labor force is relatively cheap, it also increases the chance of pollution tips! In addition, in recent years, a new form of packaging has emerged, that is, refilling (8 plates or 10 plates of suction heads are stacked into a tower, and the tips can be quickly loaded into the suction box head without touching the tips
).
This tip requires less storage space and significantly reduces the use of plastic, thus achieving environmental protection purposes
.
Although the domestic share of this form is still minimal, it must be the trend of the times in the long run
.
