Product Details
Burette, Rotaflow Key with PTFE Needle Valve Class A
Precision Titration with Micro-Drop Control
The Rotaflow Class A Burette represents the pinnacle of titration control. Unlike traditional stopcocks, the PTFE Needle Valve design allows for incredibly fine adjustment, enabling the user to deliver single micro-drops with ease. Ideal for critical analytical chemistry and research applications.
Rotaflow Control
The high-performance needle valve ensures smooth rotation and eliminates the "stick-slip" motion common in glass stopcocks.
PTFE Needle
Chemical-resistant PTFE needle provides a leak-proof seal without the need for lubrication, preventing sample contamination.
