Nalgene* HDPE Pipette Washer-Rinsers

One-piece leakproof washer-rinser offers a wide range of cycling speeds. Operates with water input from 1 1/2 to 12 liters per minute without "siphon-stall."� Water inlet at top eliminates the risk of back-siphoning contaminated water into the water line when there is a drop in water pressure. Tubing for both inlet and outlet is packed with each unit, ready for immediate installation.
