Because it is a disposable medical consumable, the biggest role of the suction filter is to prevent cross-infection during use, and its filter is machine-loaded to ensure that the tip is completely unaffected during manufacturing and packaging.

In addition, the filter nozzle is pre-sterilized by radiation after packaging to enhance the protection of biological samples, and the use of filter element suction can be used to prevent the pipette from being damaged by the sample, greatly improving the service life of the pipette.

The cartridge suction helps to reduce the possibility of smoke formation and prevent aerosol contamination, thereby protecting the pipette shaft from cross-contamination, in addition, the filter barrier prevents the sample from being carried away from the pipette, thereby preventing pcr contamination, and also prevents the pipette from being damaged by the sample entering the pipette during the pipette process.
