Difference between Ordinary Pipette Tip and Filtered Pipette Tip

When we try to measure and transport very small amounts and fixed volumes of liquid, which is usually less than 10mL, it’s important to find a way to prevent cross-contamination and damage to samples effectively. It’s also concerned by the scientists in the labs to make sure that the sample aspiration is accurate and precise, and the user is protected by preventing sample liquid from entering the pipette body.

All you need is the pipette tip, a type of useful chemical dropper which is used with a pipette to speed up the process and reduce cross-contamination. Available in a variety of materials and styles, to the popular pipette styles, the pipette tips made by Hawach are advanced pipette tips, standard pipette tips, and advanced filter pipette tips.

As laboratory tests become more and more sensitive, and tip requirements are stringent over time, Hawach pipette tips are always satisfied with better sealing and no leakage, the maximum sample liquid recovery, and perfect fit for the pipettes from almost all the famous brands. The unique and creative design of Hawach pipette tips can also help to reduce the occurrence of liquid hanging on the wall, in which way the liquid measuring and transportation will be fast and accurate.

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.

Stability of Filtered Pipette Tip
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.

Uneasy Adhesion of Filter tips
Hawach 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.

Measurement Accuracy of Filter tips
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.
