Installation and Use of Laboratory Stainless Steel Triple-Branches Vacuum Filtration Units

Vacuum filtration devices are mainly used in liquid chromatography mobile phase filtration, particulate matter analysis, and microbial contamination detection. They are standard equipment in chemical laboratories.

The laboratory three-branch vacuum filtration system adopts an innovative design, which can connect 3 funnels to filter 3 groups of samples at one time, which is suitable for users with a large amount of testing. The whole filter bracket is made of anodized aluminum alloy material, which is durable, light in weight, and can be sterilized at high temperatures and high pressure; the suction filter pump adopts an oil-free design, which can be directly connected to the power supply, with low noise and low vibration; with double anti-waste liquid suction protection design, can completely eliminate the phenomenon of sucking back.

HAWACH laboratory three-branch stainless steel vacuum filtration device is made of all 316L microbial stainless steel, which is suitable for the use of membrane filtration in the laboratory to detect microorganisms and suspended solids indicators in water. The bracket has 3 regulating valves, corresponding to 3 funnels, and each funnel can independently control and adjust the filtration speed.

Stainless Steel Three-Branches Vacuum Filtrations

How To Assemble Laboratory Stainless Steel Triple-Branches Vacuum Filtration Units?

1. Take out the various parts of the HAWACH laboratory triple stainless steel vacuum filtration device – filter seat, suction filtration, and waste liquid bottle respectively, remove the packaging and place it on a horizontal table.
2. Please connect the suction end of the vacuum pump and the suction end of the waste liquid bottle with the pump tube with the water-blocking filter. The interface of the suction end of the waste liquid bottle is the end with the water-blocking protector below.
3. Please use a silicone tube to connect the inlet end of the waste liquid bottle and the interface end of the triple stainless steel filter base.
4. Please confirm that all silicone tube connections are completely sealed.

How To Operate Laboratory Stainless Steel Triple-Branches Vacuum Filtration Units?

1. Confirm that all stainless steel valves are closed and turn the stainless steel gas regulating valve clockwise to close (the gas regulating valve is located at the end of the filter seat).
2. Put the stainless steel filter membrane gasket of each filter base into the filter base, there is no groove in the base, make sure that the gasket is completely embedded in the groove.
3. Use a stainless steel cup to press the filter membrane and rotate it to fix it on the filter base.
4. If sterilization is necessary, the vacuum suction bottle, filter seat, filter membrane gasket, filter cup, and connecting pipeline can be sterilized by high temperature and high pressure before using this product.
5. Turn on the vacuum pump and adjust it to the required vacuum degree, and the filtration rate is not easy to be too fast.
6. Put the filtered solution into the funnel, and start filtering by opening the stainless steel valve.
7. Turn counterclockwise the gas regulating valve of stainless steel in order to remove the residual solution in the pipeline, after completing the filtration.
8. After filtering one set of water samples, use a flame spray gun to sterilize the base and gasket before replacing another set.

Use Notes Of Laboratory Stainless Steel Triple-Branches Vacuum Filtration Units

1. After use, the stainless steel filter seat should be cleaned in time.
2. Do not use a hard brush, which will scratch the surface of the stainless steel filter seat.
3. Stainless steel filter seat, vacuum waste liquid bottle, connecting pipeline, etc., all components except suction filter pump can be sterilized by high temperature and high pressure.
4. Do not use any cleaning agent to clean this product, it is easy to cause cracking and damage to the vacuum waste liquid bottle and silica gel.
