Technical Field
The invention relates to the technical field of experimental equipment, in particular to a novel sample filter.
Background
In general, in the experiment of environmental samples, in order to avoid the impurities in the samples from blocking the pipelines of the experimental instrument, filtration is generally carried out before a machine is used, which is commonly called a membrane, and the membranes are usually 0.22um and 0.45 um. The filters are typically syringes with volumes of 1.00ml, 2.5ml, and 5.0ml and 10 ml. The containers for the samples are typically 10mL/15mL polyethylene centrifuge tubes. In general experiments, gloves are worn, so that during filtration, a filter membrane and a syringe are manually installed, and manual filtration is performed, which have the chance of contacting a filter head, and cause pollution. Furthermore, for 5.0mL or more syringes or 0.22um filters, hand pressure is typically high and, in larger quantities, the chance of hand fatigue and contamination increases.
To this end, we propose a new sample filter to solve the above problems.
