Class A Volumetric Flask with Snap Cap

Key Functional Benefits:

• Quick-Seal Snap Caps: The plastic snap caps provide a secure, leak-proof closure that is easy to apply and remove with one hand, making them ideal for high-throughput labs
• Exceptional Visibility: Features a sharp, permanent graduation line and large white block lettering for easy volume verification and inventory management
• Rugged Design: The machine-blown body ensures uniform wall thickness, and the heavy beaded neck prevents chipping during frequent cap application
• Chemical Resistance: Borosilicate glass provides superior resistance to thermal shock and chemical attack, ensuring your reagents remain uncontaminated

Laboratory Management Insights:

• Mixing Technique: When inverting the flask to mix solutions, ensure the snap cap is firmly seated by applying thumb pressure. For highly volatile or hazardous chemicals, a ground glass stopper model may be preferred for a more hermetic seal.
• Cap Replacement: While the glass body lasts for years, plastic snap caps can become brittle over time if exposed to harsh solvent vapors. Periodically inspect caps for cracks to maintain a leak-proof seal.
• Thermal Calibration: To maintain the certified Class A accuracy, only use these flasks at or near $20^{\circ}C$. Do not use these flasks for heating liquids, as this can permanently alter the volume calibration.
