Key Features

1. High-Quality Borosilicate Glass Construction ​ ​Made from premium 3.3 borosilicate glass, these titration bottles offer exceptional resistance to thermal shock, chemical corrosion, and mechanical stress. This material ensures the bottles remain stable even when exposed to extreme temperature changes, making them suitable for storing a wide range of reagents, from acidic to alkaline solutions. The non-porous surface prevents absorption or leaching, preserving the purity of your samples. ​ ​2. Dual Color Options for Specific Needs ​ ​Transparent Glass Bottles: Ideal for storing solutions that do not require light protection. The clear glass allows easy visual inspection of liquid levels, color changes, and sedimentation, ensuring you can monitor your samples at a glance. ​ ​Amber Glass Bottles: Designed to protect light-sensitive reagents, such as photosensitive chemicals, organic compounds, and certain pharmaceuticals. The amber glass effectively filters out harmful UV rays, preventing degradation and maintaining the integrity of your substances over time. ​ ​3. Precise Graduations for Accurate Measurements ​ ​Each bottle features clear, permanent graduation markings that allow for precise volume readings. The markings are etched using advanced techniques, ensuring they remain legible even after repeated use and cleaning. Whether you’re preparing standard solutions, performing titrations, or dispensing liquids, these graduations enable accurate and consistent measurements. ​ ​4. Leak-Proof and Secure Design ​ ​The bottles come with ground glass stoppers that create an airtight seal, preventing leaks and contamination. The stoppers are precisely matched to the bottle necks, ensuring a snug fit that keeps your reagents safe from evaporation, dust, and external pollutants. This design also makes the bottles suitable for long-term storage of sensitive solutions. ​ ​5. Multiple Capacity Options ​ ​30ml: Perfect for small-scale experiments, storing rare or expensive reagents, or when space is limited. ​ ​60ml: A versatile size that balances capacity and portability, ideal for routine laboratory use and general titration tasks. ​ ​125ml: Designed for larger volume requirements, suitable for storing bulk solutions or conducting extended experiments.
