Perfect for screwing onto our 1oz MEKP bottles! These caps eliminate messy pouring, allow measurement by drops and can be capped for clean storage.  

These unique bottles are made to accurately dispense MEKP. The 16 oz bottle is graduated to measure up to 35 cc's at a time, while the 32 oz bottle can measure up to 100 cc's at a time. Simply squeeze the bottle until the upper vial is full, then release pressure on the bottle, leaving a precisely measured amount of catalyst in the vial. The MEKP can then be poured out with no dripping.
