Narrow Mouth Reagent Bottle 500 mL with Plastic Stopcock

Narrow Mouth Reagent Bottle 500 mL | Chemical-Resistant Plastic Stopcock

Our Narrow Mouth Reagent Bottle 500 mL is the gold standard for secure liquid storage and controlled dispensing in laboratory environments. Crafted from high-clarity Borosilicate 3.3 glass, this bottle is designed to handle corrosive chemicals, solvents, and volatile liquids. The integrated Plastic (PTFE/PP) Stopcock at the base provides a leak-proof seal and allows for precision pouring without the need for heavy lifting or external funnels.

Key Features

• Premium Borosilicate 3.3 Glass: Highly resistant to thermal shock and chemical attack. Ideal for storing acids, bases, and high-purity reagents.

• Precision Control Stopcock: Features a smooth-action plastic stopcock that ensures a drip-free, airtight seal and prevents “freezing” common with glass-on-glass joints.

• Narrow Mouth Design: Engineered to reduce evaporation and protect against accidental spills while providing superior control during liquid transfer.

• Permanent Graduations: Clear, easy-to-read white enamel volume markings and a large marking spot for convenient sample identification.

• Superior Seal: Includes a heavy-duty ground glass or plastic stopper (depending on selection) to maintain the integrity of sensitive chemicals.
