What Are The Advantages of The Three-layer Filter We Developed?

Our double-layer filter has three advantages: 1. The tip uses a double-layer filter element to prevent contamination. The white filter (2/3), with a small pore size of 10 μm, blocks liquid, sputtering and atmospheric sol molecules, and the blue filter (1/3) ), with a very small pore size of 5 μm, effectively blocking tiny particles such as aerosols and biomolecules; 2. Double-layer ultrafiltration tip, the white filter intercepts droplets and splashes, and the yellow or other color filter effectively blocks the sample solution! 3. In addition to the above advantages of the double-layer filter tip, it can also block excess liquid. White and yellow or other color filter can be made into water-sealed filter . When the yellow or other color filter encounters liquid, it has a self-sealing function. The main advantages of the two-color filter lie in these 3 points! However, the disadvantage is that the two-color filter cannot realize large-scale automatic filling of the filter in the suction head.

Now we have developed a three-layer filter that can combine the three existing advantages of a double-layer filter and at the same time solve the problem of automatic filling!!! The existing double-layer filter is installed with the blue surface with small pores facing up and the white small pores facing down. When the gun is discharged during pipetting, the aerosol is blocked in the white small pore size 10 μm filter and the blue small pore size 5 μm filter , and the disadvantage is that it is impossible to automate a large amount of filling. Three-color filter can solve the problem of automated filling. The middle one is a filter with tiny pores of 5 μm. The white filter on both sides can be made into 10 μm small pores with water sealing function Filter.
