Features High quality stainless steel for raw materials, laser cutting and welding; Firmness is effectively guaranteed. The filter hole on the funnel is completed with CNC laser cutting machine, and the hole position is precise. Need to use with filter paper or filter cloth or filter net. The use of the composite seal , ensure the instrument internal negative pressure can reach -0.098Mpa w.
