Saint Stephen's polysulfone plastic material vacuum filtration device

● Application areas:

Saint Stephen's polysulfone plastic material vacuum filtration deviceFS300F-T3 and FS300F-T5 are suitable for fluoride analysis and determination of various water samples. Sample pretreatment and filtration are carried out to remove suspended particles or other impurities that may interfere with the detection results.

● Product features:

1. The filter bottle group is made of low adsorption polysulfone resin material,Saint Stephen's polysulfone plastic material vacuum filtration deviceFS300F-T3 and FS300F-T5 have no glass components

Due to the silicate component in the glass material, it can adsorb fluoride ions in the water sample to be tested, thereby affecting the detection results. As a vacuum filtration device specifically designed for the determination of fluoride in water samples, the filter bottle assembly of this series is injection molded with more stable and low adsorption polysulfone resin material, which does not react with fluoride ions and provides more accurate detection results.

2. The scale line and bottle body are integrally formed

The filter cup and the collection bottle are both marked with scale lines and are formed synchronously through the precision etching structure of the mold cavity using in mold molding technology. Physically integrated, not afraid of scratches. No ink adhesion, even in long-term contact with various water samples including sewage or industrial wastewater, it can still be used for a long time without fading.

3. The replaceable mold design of magnetic adsorption structure provides higher efficiency in laying and replacing filter membranes

The filter bottle set can be reused, and the filter membrane can be replaced. The connection between the filter cup and the filter membrane placement base abandons the traditional method of fixing accessories such as fixtures and clamps, and adopts a magnetic adsorption structure. It also combines the convenience of removing the filter cup with one hand and better sealing.

4. Automatically close the suction port of the collection bottle when the liquid is full to prevent the overflow of filtrate

The suction port of the vacuum collection bottle is equipped with a floating ball check valve component on the inside. When the liquid level rises to the bottle mouth, if the operator does not handle it in time, the check valve will automatically rise and block the suction port under the buoyancy effect, which can prevent the liquid from overflowing from the suction port when the bottle is full.

5. The suction funnel and collection bottle are connected with rubber plugs for better sealing

The use of silicone plugs to connect the suction funnel and the collection bottle provides better airtightness, providing better vacuum and negative pressure attraction for filtration, significantly improving the filtration efficiency.

6. Provide two specifications of filter cups, which can be selected according to needs

The capacity of the collection bottle is 1200ml, and the filter cup is available in two capacities: 300ml and 500ml. Users can choose the appropriate specification according to the sample size or relevant testing requirements.

7. Vacuum pump specially designed for filtration

The suction pump adopts a dry structure, which can be used by plugging in electricity, does not require maintenance, and does not produce oil mist pollution; No vibration and low noise during work; Equipped with a vacuum gauge and regulating valve, it is easy to observe the working status of the vacuum system and adjust the suction and filtration speed as needed; The air inlet is equipped with a buffer cup and a dust blocking filter element, which can prevent dust particles or filtrate from being sucked into the pump body.

8. The water blocking protector can effectively block the backflow of filtrate

The vacuum pump tube is equipped with a water blocking protector in the middle to prevent liquid backflow, with a built-in hydrophobic PTFE filter element. In case of an accident of liquid backflow, the liquid sucked into the water blocking protector will also be blocked by the filter element, ensuring the safe use of the equipment.
