Low-cost PC holder for the filtration of large-volume of aqueous solutions. This practical holder is suitable for many simple laboratory filtrations. It can be connected to a peristaltic pump or a pressure container. The bell-shaped base protects the filtrate from repeated contamination while flowing in a receiver. Sterilisation by autoclaving at 121 °C. Low-cost PC holder for the filtration of large-volume of aqueous solutions. This practical holder is suitable for many simple laboratory filtrations.
