Product features

Filter pump with stopcock(improved type) is a long bulb with side branch tube. A bamboo-shaped glass tube is welded to the upper end of the bulb. There is a narrow nozzle in the long bulb welded to the bamboo-shaped glass tube, which is vertical extending down to the bottom of the elongated bulb, a single automatic stopcock is added to the side branch tube.

Filter pump with stopcock is made of high quality borosilicate glass, which has good chemical stability and corrosion resistance, and can maintain stable performance in various chemical experimental environments. The transparency of the glass material is high, so that the operator can clearly observe the water flow and gas flow inside the suction pipe and find problems and adjust them in time. The main body of the pump provides a more smooth channel for the gas flow, improves the pumping efficiency, and can achieve the required vacuum or gas discharge effect in a shorter time. The existence of the valve can better control the gas in and out, and protect the safety of the experimental device and the experimental sample. Filter pump itself has good stability, can be used in the process of keeping upright, not easy to tip or shake. Whether it is a rubber tube connection or another connection method, the connection can be completed quickly and firmly, saves time for experimental preparation. Filter pump with stopcock is easy to operate and has relatively low water quality requirements.

Filter pump with stopcock has low expansion rate, high temperature resistance, acid and alkali resistance, high strength, high hardness, high light transmittance, high chemical stability, smooth tube diameter is no protrusions, beautiful appearance, and solid workmanship,good light transmittance, high transparency, beautiful appearance, smooth welding, smooth bottle body, welded in one body.
