Pipette tips come in three different types including non-sterile, pre-sterilized and filtered tips.
The most commonly used type of pipette tip is non-sterile tips. They are often used in laboratory applications where sterility is not important to the experiment or test being performed. On the other hand, pre-sterilized pipette tips are designed to prevent contamination. They are certified free of DNA, RNase, ATP and pyrogens. Because these pipette tips are certified free of DNA, RNase, ATP and pyrogens, they are ideal for applications that require sterility such as cell cultures.
With ordinary pipette tips, the aerosol/water vapor in the sample can contaminate the pipette, and further contaminate the next sample, or cause potential harm to the operator. The filter element is hydrophobic, which can prevent aerosol/water vapor from entering the pipette. The filtered Pipette Tip is made of ultra-high molecular weight polyethylene, which is hydrophobic, which can prevent the sample from entering the pipette and prevent impurities in the pipette from contaminating the sample. It is recommended for PCR, radioactivity, biological toxicity, corrosive, and volatile sample loading operations. Moreover, it mainly has the following three characteristics: prevent sample cross contamination; reduce the biological hazards of operators; improve experiment repeatability.
Filtered pipette tip can realize automatic sewage discharge to ensure the stability of the water quality and output; the filter element does not need to be filled with protective liquid, which is convenient for transportation and storage; it is packaged with high-quality hollow fiber membrane filament materials, and the product has high filling density and large water output; good chemistry stability, acid and alkali resistance, and bacteria resistance. It has good hydrophilicity, strong anti-pollution ability, and it is not easy to foul up.
Filtered pipette tips are characterized by high porosity and smooth outer surface, which can effectively ensure a greater flow per unit area, easy back washing, and uneasy adhesion for impurities. The impurities cannot be retained in the filter body with anti-fouling ability. And the small size of the filter is of good resistance to strong acid and organic solvents. What’s more, its excellent mechanical properties can greatly ensure no particle release. Advanced injection molding technology and attractive mold design make it perform superior, and match single channel or multi-channel pipettes perfectly in different areas. The standard size and the smooth inner wall are suitable to reduce residue in performance and greatly ensure the accuracy of operation. Super quality filter elements and unique processing technology build solid barriers to eliminate contamination risk.
A pipette tip is a laboratory tool, which is commonly used in chemistry and biology to work as a media dispenser. Pipette tips are of several designs for various purposes with diverse accuracy and precision. Some pipettes have complex adjustable or electronic properties which can create a partial vacuum and selectively release different vacuums to absorb and dispense liquid. Measurement accuracy and selection are greatly affected by the style of an applied situation.
