Abstract
The utility model discloses a microbial limit filtering device comprising a filter and a pipeline system. The pipeline system comprises an air exhausting pipeline, an air exhausting pump and a control valve; the control valve is arranged at the lower end of the filter and is connected with the air exhausting pipeline; and the air exhausting pump is connected with the air exhausting pipeline. The microbial limit filtering device provided by the utility model uses the control valve, so that a negative pressure in the pipeline is controlled, therefore, no pollution is caused when a cup body or a filter membrane of the filter is taken off, and the accuracy of a detecting result is ensured.
Description
Technical field
The utility model relates to a kind of filtration unit that detects microbial limit.
Background technology
The limit test of microbe method is that inspection non-regulation sterilization preparation and raw material thereof, auxiliary material receive the microbial contamination degree methods.Inspection item comprises bacterial count, fungi count, yeast count and the inspection of control bacterium.Carry out in the way flow air section of 100 grades of local cleanliness factors that limit test of microbe should be under 10000 grades of environment cleanliness.The check whole process must strictly observe aseptic technique, prevents recontaminate.Way flow air section, work top and environment should regularly be pressed the current national standard of " testing method of medicine industry clean room (district) suspended particles, swim bacterium and sedimentation bacterium " and carry out the cleanliness factor checking.
Existing microbial limit filtration unit can be seeded in after filtering membrane being taken off again and cultivate observation cultivation results in back on the substratum, thereby trial-product is carried out limit test with trial-product through the filtering membrane on the filtration unit.This filtration unit comprises suction filtration head and vacuum pump, and suction filtration head and vacuum pump after suction filtration is accomplished, because remain in the pipeline in negative pressure, possibly cause filtering membrane to be difficult for taking off with hose connection, make film contaminated, causes the check failure.
The utility model content
The purpose of the utility model is to overcome the existing not easily detachable problem of microbial limit filtration unit filtering membrane; A kind of new microbial limit filtration unit is provided; Negative pressure in can pilot piping reduces and gets filtering membrane or filter the pollution that cup causes, and guarantees the accuracy of assay.
The technical scheme of the utility model is: a kind of microbial limit filtration unit; Comprise strainer and tubing system; Tubing system comprises bleed line, off-gas pump and valve, and the lower end that said valve is arranged on strainer is connected with bleed line, and off-gas pump is connected with bleed line.Through the negative pressure of valve in can pilot piping, can be not contaminated when filtering membrane on the strainer is taken off.
Said valve is connected through spirane structure with strainer.The dress of the spirane structure convenient filter between valve and the strainer with get.
Said off-gas pump is a diaphragm-type vacuum pump.
Said off-gas pump is connected with valve through the conduit coupling that is arranged on the bleed line.
Said strainer comprises cup, filtering head and filter membrane, and cup is arranged on the filtering head, and filter membrane is arranged between filtering head and cup, is provided with bleed-off passage in the filtering head and communicates with bleed line.
The beneficial effect of the utility model:
The utility model makes the negative pressure in the pipeline be able to control through adopting valve, when taking off strainer cup or filtering membrane, can not pollute, and has guaranteed the accuracy of detected result.
