Automatic Zero Burette (Amber): Precision Volumetric Titration
Professional-grade, UV-protective amber glass burettes with automatic zeroing for light-sensitive reagents.
Self-Zeroing Accuracy for Light-Sensitive Liquids
The Automatic Zero Burette in Amber Glass is a high-precision volumetric instrument designed for titrations involving light-sensitive chemicals such as Silver Nitrate ($AgNO_3$) or Potassium Permanganate ($KMnO_4$). The deep amber color is integral to the glass, providing permanent protection against UV radiation and chemical degradation.
The Automatic Zero mechanism allows for rapid, repeatable filling. By simply squeezing a reservoir bottle (not included) or using a pressure bulb, the liquid rises to the top and automatically overflows to the exact zero mark, eliminating meniscus-level errors and speeding up laboratory workflows.
Key Technical Features
- UV-Protective Amber Glass: Permanent amber stain ensures reagents remain stable and do not photo-decompose during long experiments.
- Automatic Zeroing: Sophisticated overflow system ensures the liquid level starts at exactly "0" every time.
- High-Quality Stopcock: Available with precision-ground glass or PTFE (Teflon) stopcocks for leak-proof, smooth control over elution.
- Permanent Graduation: White enamel markings provide sharp contrast against the amber glass for easy volume reading.
- Chemical Resistance: Manufactured from Borosilicate 3.3 glass to withstand aggressive titrants.
