A Brief Introduction of Pipette Filter Tip and Assembly of the Tip

Filter tips
Filter tips are to help avoid cross-contamination. Generally speaking, there is no problem when using filter tips for forwarding pipetting operations. The filter tip is made of medical grade polypropylene, and the filter element is made of ultra-high molecular weight polyethylene, which has good hydrophobicity and can perfectly block aerosols and prevent fluid and liquid vapor from polluting the interior of the pipette. It’s suitable for handling demanding molecular biology samples such as PCR samples and dealing with dangerous samples such as radioactivity, biological poisoning, corrosiveness, and volatility.

(1) The filter element effectively forms a protective structure between the pipette and the sample to ensure the safety of sample aspiration; reduce the hazard of the gas residue and improve experiment repeatability.
(2) It provides low-adsorption and ordinary filter tips, no coating design, will not pollute the sample, the surface of the low-adsorption tips is completely hydrophobic.
(3) High temperature and high pressure sterilization can be used.
(4) Available in both filter and filterless versions. The main purpose of the filter element is to prevent the sample from contaminating the pipette tip.
(5) High temperature resistance (121℃), all products ensure no pyrogens.
(6) Smooth pipe wall reduces liquid adhesion, environmental protection, and energy conservation.
(7) Gamma ray sterilization.
(8) The color of the tip of different measuring ranges is different.

Triple guarantees
Personnel safety guarantee: reduce the spread of harmful samples and protect the health of operators.
Sample safety guarantee: prevent cross-contamination between samples and contamination of internal impurities in the pipette, ensure that the samples meet the requirements of subsequent experiments (no DNase/RNase, no PCR inhibitors, etc.), and minimize sample loss.
Equipment safety guarantee: avoid liquid overshooting into the pipette cavity, maintain the precision and accuracy of pipetting, and extend the service life of the pipette.

Assembly of the tip
When putting the tip of the pipette on the pipette, many people will knock a few times on the tip box. This is a wrong approach because this will cause the internal parts of the pipette gun (such as springs) to be instantaneous due to the tapping. The impact force becomes loose and even causes the scale adjustment knob to jam. The correct method is to insert the pipette gun vertically into the tip of the pipette, and turn it slightly left and right to make it tightly combined. If it is a multi-channel (such as 8-channel or 12-channel) pipette, you can aim the pipette at the tip of the pipette, then insert it at an angle, and shake it forward and backward to lock it. The sign that the gun tip is clamped is slightly beyond the O-ring, and you can see that the connecting part forms a clear sealing ring.
