Abstract

The invention discloses a full-automatic thin film suction filter which comprises suction filtering cups, a shell, a pipeline, an electromagnetic valve, a water pump, liquid sensors and an in-place sensor. At least two suction filtering cups are mounted on the shell, the pipeline, the electromagnetic valve, the water pump, the liquid sensors and the in-place sensor are positioned in the shell, each suction filtering cup is connected to the water pump through the pipeline, an electromagnetic valve is arranged on the pipeline, and the in-place sensor is arranged at a position where the suction filtering cup is connected with the shell and connected with the water pump and the electromagnetic valve electrically. A circuit board is arranged in the shell, part of the pipeline is arranged on the circuit board, and the liquid sensors are distributed at positions, on two sides of the pipeline, of the circuit board and electrically connected with the water pump and the electromagnetic valve. Sensing is realized in the whole process through the in-place sensor and the liquid sensors, so that artificial judgment and operation are not needed, manpower and time are saved greatly, and working efficiency is improved greatly.

Description

technical field [0001] The invention relates to a fully automatic membrane filtration suction filter, which belongs to the technical field of microbial limit detection of liquid samples. Background technique [0002] The purpose of suction filtration of liquid samples is to detect whether the limit of microorganisms in liquid samples, such as beverages, pharmaceuticals, biological agents, biological reagents, hospital treatment water, and disinfectants, exceeds the standard. [0003] The above detection methods specified in the national standard and industry standards (such as GB, GMP, Pharmacopoeia) have the filter membrane method. The principle is that 0.45um bacteria cannot pass through the filter membrane and are intercepted on the filter membrane, and then the filter membrane is taken out. Next, stick it face up on the surface of the agar medium, incubate, count the number of colonies grown after 48 hours, and judge whether the result exceeds the standard according to...
