Overview
The Brown volumetric flask utilized in the laboratory is fabricated from glass, exhibiting favorable chemical stability and thermal shock resistance. It is furnished with a glass stopper to guarantee tight sealing. The flask's slender-necked and pear-shaped design, along with a flat-bottomed structure, ensures stability and is applicable in scientific research fields such as chemistry, biology, and medicine. With Class A precision and a minor error margin, it is suitable for high-precision experiments. The brown glass effectively inhibits the decomposition of light-sensitive substances and has an extended service life.
Features
1. Precision: Class A , featuring a small error and ensuring measurement accuracy.
2. Light-shielding property: The brown glass blocks ultraviolet rays and is suitable for light-sensitive solutions.
3. Bottle stopper: The glass stopper has excellent sealing performance, ensuring that the solution is not contaminated by the external environment.
4. Graduation: The white printed marks and circular graduation lines are clear and legible.
Technical data
Working Environment Conditions:
1. Temperature: Ranging from 15°C to 25°C to guarantee measurement precision.
2. Humidity: Between 30% and 70% to prevent condensation and influence on readings.
3. Illumination: Strong direct light, especially ultraviolet light, should be avoided.
4. Cleanliness: Maintain cleanliness of the laboratory to prevent contamination.
5. Vibration: Keep away from vibration sources to evade interference.
6. Chemical Environment: Avoid exposure to corrosive chemicals such as strong acids and strong bases.
Precautions:
1. Stopper Inspection: Prior to usage, inspect whether the stopper is tightly sealed to ensure no leakage.
2. Heating Prohibition: Capacity bottles are not subject to heating. Hot solutions need to be cooled to room temperature before being injected.
3. Solution Transfer: Dissolve the substance in a small beaker initially, and then quantitatively transfer it to the capacity bottle. During the transfer, use a glass rod for guidance.
4. Volume Adjustment Method: When adding purified water close to the marking line, add it dropwise with caution until the bottom of the solution meniscus is tangent to the marking line.
5. Shaking Procedure: Press the stopper with one hand and support the bottom with the other, then invert and shake approximately 15 times.
6. Short-Term Storage: Capacity bottles can store solutions for a short period but not for an extended time, especially alkaline solutions.
7. Treatment for Long-Term Non-Use: When not in use for a long time, clean it thoroughly and pad the stopper with paper.
8. Avoid Grasping the Bottle Body: Do not hold the bottle body with your hand to avoid liquid expansion.
