Kartell 206305 Cup with 250mL Reservoir Bottle Lab Adjustable Volume Dispenser, 5-25mL Volume (Pack of 10)

This 250mL low density polyethyelene dispenser bottle features a graduated clear PMP measuring cup that slides up and down on the vertical polyethylene tube for easy adjustment. The variation in height determines the volume to be dispensed. The cup is filled by squeezing the bottle and forcing the liquid up the tube. When the bottle pressure is released, the excess will be drawn back into the bottle and only the desired volume will remain. Cup measures volumes from 5 - 25mL. Dynalon #: 206305.
