The Rotaflow valve replaces the fiddly traditional glass key with a smooth-turning, grease-free PTFE key that doesn't seize or leak. Bold, permanent graduations on the clear glass column let students, researchers and technicians control delivery down to the last drop without tiring their hands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRotaflow valve: A PTFE screw-thread stopcock gives smooth, fine control over single-drop dispensing, without messy grease.\u003c\/li\u003e\n\u003cli\u003eLeak-proof and non-seizing: Traditional glass keys can jam or leak over time.
