1. The suction head is made of medical grade polypropylene, while the filter element is made of ultra-high molecular weight polyethylene, which has good hydrophobicity.

2. Can withstand high temperature autoclave treatment.

3. The design of filter element suction head is extended, easy to operate.

4. No RNase, no DNase, no heat source, to ensure the safety of the experiment.

5. The filter element forms an effective protective barrier between the pipette and the sample, improving the safety of sampling, while reducing the harm of the gas residue in the gun body to the operator during pipetting, and improving the repeatability of the experiment.
