Product Overview:
The dual stainless steel membrane filter (suction filtration device) is a new type of solution filtration device used in chemical laboratories. Multiple samples can be filtered simultaneously or separately. Improve the efficiency of experimental work. Widely used in liquid filtration for chemical analysis, instrument analysis, hygiene inspection, pharmaceutical industry, biological products and pesticides, petroleum, environmental monitoring, tap water, sewage bacteria and other fields.

Product Features:
1. Only one vacuum gas source is needed to complete all operations, saving a lot of time and making it convenient and fast
2. Each support has an independent switch that can be operated independently.
3. The stable low center of gravity design prevents it from tipping over due to the solution being fully loaded.
4. Made of high-quality stainless steel material with excellent corrosion resistance
5. Using a dual cylinder piston pump as the negative pressure source, there is no oil mist pollution, maintenance free, high pumping rate, and high maximum negative pressure.
6. Adopting oil-free lubrication piston pump, no oil mist pollution to the environment;
7. High negative pressure, large flow rate, fast suction speed. The required negative pressure during suction can be controlled by a negative pressure regulating device and displayed on a negative pressure gauge;
8. The overflow protection device can reliably and effectively prevent liquid from entering the pump;
9. Plastic box shell is beautiful, lightweight, and easy to carry;
10. Equipped with a 1000ml polycarbonate plastic storage bottle, it is durable, easy to clean, and can be sterilized at high temperatures.
