Flasks, Erlenmeyer’s (pp Stopper)

What is it?

The Erlenmeyer Flask (also known as a Conical Flask) is a staple of every laboratory. Its unique flat base and tapered neck allow for vigorous swirling and mixing of liquids without the risk of splashing. This version is equipped with a Polypropylene (PP) Stopper, which fits into a precision-ground neck to provide an airtight seal, making it ideal for storing sensitive chemicals or preventing evaporation during reactions.

Key Features and Benefits

• Premium Borosilicate 3.3 Glass: Engineered for high thermal shock resistance, allowing the flask to be heated safely over a burner or in an incubator.
• Chemical-Resistant PP Stopper: The lightweight Polypropylene stopper is highly resistant to acids and bases and provides a non-stick, airtight seal that is easy to remove.
• Interchangeable Ground Neck: Features a standard ground-glass joint (e.g., 24/29), ensuring the PP stopper is easily replaceable and fits perfectly every time.
• Clear, Durable Graduations: Printed with high-visibility white enamel scales for easy reading of liquid volumes and approximate measurements.
• Stable Conical Shape: The wide base prevents tipping and is specifically designed to handle rapid swirling for titration and sample preparation.
