Everyone is generally very cautious when buying pipettes. They want to spend some price to buy a good brand with high precision; but we don’t pay much attention when buying pipette tips, and we will buy some cost-effective ones at will. In fact, the tip is also the first condition to jeopardize the test results, and it is also likely to jeopardize the service life of the pipette.

There are three types of pipette tips: normal, filter and low retention.
1. Ordinary tips: and tip boxes can be autoclaved at 121°C/15psi. It is suitable for pipettes of different brands and models, with good compatibility. The tube body is clear and the scale line is clear, which is easy to observe when using. Solvent resistance. Affordable paper bag packaging, reasonable PE bag packaging to avoid environmental pollution.
2. Filter tip: Some students often report that when the pipette gun is disassembled and repaired, they can't bear to look directly inside, and the piston rod of the stainless steel plate is etched. How to solve it? At this point, filter tips can be considered.
The filter tip is a new upgrade of the ordinary tip. On the basis of the general suction head, the filter suction head is added, and the diameter is enlarged, which ensures excellent ventilation while isolating the actual effect. There are several models: 10/100/200/1000 microliters. Color is completely transparent.
There are three major advantages: ① Ensure the safety of testers: It can reduce the spread of dangerous goods and ensure the life safety of actual operators to a greater extent. ②Ensure sample safety: no pyrogen, no Dnase/Rnase, no PCR inhibitor, to avoid cross-environmental contamination. ③Ensure the safe use of the pipette: prevent the liquid from rushing into the cavity, maintain accuracy and accuracy, and increase the service life of the pipette.
3. Low adsorption tips: The surface layer is treated with a hydrophobic solution, which can reduce the situation that low interfacial tension liquids leave more residues in the tips. It can minimize sample damage, prevent protein digestion and absorption, and easily remove sticky raw materials, genetic DNA or fragile cell culture substrates, which is a better guarantee for high-precision test results.
