Product Overview:
The DL-5B five link glass 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 in chemical analysis, instrument analysis, hygiene inspection, pharmaceutical industry, biological products and pesticides, petroleum, environmental monitoring, tap water, sewage and other fields.

Product features:
1. The glass filter is composed of an oil-free vacuum pump and filtering equipment, and is divided into a funnel filter cup, a middle sand core filter head (sintered filter head), a stainless steel multi link base bracket, and an aluminum alloy fixing clip.
2. Only one vacuum gas source is needed to complete all operations, saving a lot of time and making it convenient and fast
3. Each support has an independent valve switch that can be operated independently.
4. The stable low center of gravity design prevents it from tipping over due to the solution being fully loaded.
5. Stainless steel components are polished with precision machined mirror finish, resulting in a smooth and even surface that is easy to clean and remove;
6. All stainless steel components are made of SUS304 stainless steel material with precision machining and mirror polishing, with a smooth and even surface, superior corrosion resistance, and easy cleaning;
7. The stainless steel base is made of precision machined industrial pipes with a thickness of 4mm, which has a longer service life, is sturdy, and durable.
8. The filter bottle is made of high-strength and extra hard glass, which can withstand temperature changes up to 280 ℃ and has good pressure resistance. Beautiful and elegant production, uniform wall thickness, no bubbles, international standard size, compatible with various foreign brands
9. Adopting oil-free lubrication piston pump, no oil mist pollution to the environment; Maintenance free, high pumping rate, and maximum negative pressure.
10. Equipped with a 3000ml large capacity liquid storage bottle, it is durable and easy to clean. The overflow protection device can reliably and effectively prevent liquid from entering the pump.
