Problems solved by technology

In general experiments, gloves are worn, so that when filtering, manual installation of filter membranes and syringes and manual filtration are required, all of which have the opportunity to touch the filter head and cause pollution
Moreover, for a syringe of 5.0mL or above or a filter membrane of 0.22um, usually the pressure on the hands will be high, and when the number is large, the probability of hand fatigue and contamination will increase

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a novel sample filter. Background technique [0002] In general environmental sample experiments, in order to avoid impurities in the sample from clogging the pipeline of the experimental instrument, it is usually filtered before the machine is put on the machine, commonly known as membrane passing, and the usual membranes are 0.22um and 0.45um. Filters usually use syringes with a volume of 1.00ml, 2.5ml, 5.0ml and 10ml. The sample container is usually a 10mL / 15mL polyethylene centrifuge tube. In general experiments, gloves are worn, so that when filtering, manual installation of filter membranes and syringes and manual filtration are required, all of which have the opportunity to touch the filter head and cause pollution. And for a syringe of 5.0mL or more or a filter membrane of 0.22um, usually the pressure on the hand will be very high, and when the number is ...
