Novel sample filter

The invention belongs to the technical field of experimental equipment, and particularly relates to a novel sample filter which comprises a rack, which comprises a base, wherein electric telescopic rods are arranged at the four corners of the top of the base, and a top base is arranged at the tops of the electric telescopic rods; a material collecting assembly which comprises a centrifugal tube base, wherein the centrifugal tube base is mounted in the middle of the top of the base, and a centrifugal tube body is arranged at the top of the centrifugal tube base; and a fixing assembly which comprises a carrying plate, wherein the carrying plate is installed between the electric telescopic rods. The structure is reasonable; manual filtering is replaced by a machine, so that manpower can be liberated, the labor intensity of workers can be reduced, and researchers can put more energy on scientific research; meanwhile, the situation that hands are stained with samples or cross contamination is caused can be avoided, so that the safety of workers is guaranteed; and, meanwhile, the situation that part of samples are lost due to action differences during manual filtering can be avoided, and the experiment cost is reduced.
