Product Details
Amber Burette, Rotaflow Key with PTFE Needle Valve CLASS A
UV-Protective Volumetric Glassware for Light-Sensitive Titration
Designed for high-accuracy analysis of light-sensitive chemicals, our Amber Coated Class A Burettes provide superior protection against UV radiation. The integrated Rotaflow PTFE Needle Valve offers a significant advantage over traditional stopcocks, allowing for frictionless, micro-drop control essential for critical endpoints.
UV-Shielding Amber Coating
The external amber stain ensures that light-sensitive reagents (such as Silver Nitrate or Potassium Permanganate) remain stable without compromising graduation visibility.
Precision Rotaflow Valve
The high-performance PTFE needle valve prevents "freezing" or sticking and requires no grease, ensuring a contamination-free titration environment.
