Labconco Rapidvap N2-48 13MM Block. Designed for rapid production of urine from swine these compact cylinders hold two to four liters of urine and eliminate the need for frequent lid replacements. The block is easily removed for cleaning and comes with a cleaning brush and two replacement lids. The cleaning brush is encased in a protective cap that resists rust and ensures that the nozzle is securely closed when not in use. Replacement lids are sold separately. This n2-48 block has a dimple in the center that prevents the n2 from falling out accidentally when the lid is open. Ordering Information: The color-coded gaskets allow the lid to be easily removed for cleaning and color-coded labels on the lids indicate the color change from light blue to dark brown for each n2.
