* Vacuum Filtration technique is widely used in liquid filtration in microbiological detection, SuspendedSolid detection, sample re-process or solvent purification, mostly for microanalysis of HPLC, GC, or AA in food, medicine, beverage, drinking water,etc.
* This unique design combined a filtration funnel with a receiver ask with drain, together with magnetic weighted base, guaranteeing the effeciency and stability.
