The MEDILAB Solid Glass Stopper is a precision-engineered sealing component designed specifically for B.O.D. (Biochemical Oxygen Demand) bottles. It ensures an airtight, leak-proof closure essential for accurate BOD analysis in environmental, wastewater, and research laboratories. Manufactured from high-quality borosilicate glass 3.3, the stopper provides excellent chemical and thermal stability, ensuring reliable performance in demanding laboratory conditions.

Key Features

• Precision Ground Joint: Ensures a perfect fit with B.O.D. bottles for airtight sealing.
• High Chemical Resistance: Non-reactive with common laboratory reagents, acids, alkalis, and solutions.
• Durable Construction: Made from borosilicate glass 3.3, providing exceptional thermal shock resistance and long service life.
• Smooth, Polished Finish: Allows easy insertion and removal without sticking.
• Non-Porous Surface: Prevents contamination, ensuring accurate test results.
• Universal Compatibility: Suitable for standard BOD bottles used in water, wastewater, and environmental testing labs.
• Autoclavable: Withstands high-temperature sterilisation without deformation or loss of clarity.
