Conical Flask with Ground-in Glass Stopper

– Precision, Clarity and Chemical Resistance For Your Laboratory Needs

While performing titrations, culturing media, or even mixing reagents, the stopper conical flask provides unparalleled utility, safety, and precision. Designed to withstand the harsh environments of academic, pharmaceutical, and industrial laboratories, our conical flask with ground-in glass stopper provides optimum sealing, chemical resistance, and visibility of graduations.

This flask is made from borosilicate 3.3 glass which makes it resistant to thermal shock and most chemicals. The ground-in glass stopper creates a tight seal which prevents contamination and evaporation making it ideal for sensitive or volatile compounds. Flasks are available in various sizes including the most common 100ml conical flask. They are critical to any scientific workflow.

Key Features Of 100ml conical flask

● Flask Graduated: White graduations on the flaks are clear and aid in obtaining accurate volume readings.

● Stopper Ground Glass: Shielding glass stopper ensures effective long-term chemical storage.

● Borosilicate 3.3 Glass: Strong acids, bases, and organic solvents pose no threat due to excellent thermal stability and durability.

● Seals Keep Sensitive: Under tightly sealed conditions, experiments sensitive to evaporation and exposure are safeguarded.

● Custom Orders: Sizes range from 50ml to 1000ml including standard conical flask cask sizes.

Frequently Asked Questions

Q1: What is the distinction between a stopper conical flask and a screw-cap flask?

A1: The stopper conical flask has a ground-in glass stopper that forms an airtight bond which protects from chemical infiltration. This seal is ideal for volatile, high-temperature experiments.

Q2: Is the 100ml conical flask suitable for high-accuracy measurements?

A2: It is marked with graduations, therefore, it can be used for approximate volumetric measurements. For high precision analyses, the flask should be used in conjunction with calibrated volumetric equipment.

Q3: Is the conical flask cask autoclavable?

A3: Yes, it is autoclavable and reusable when subjected to proper laboratory sterilization protocols. The conical flask is made from borosilicate 3.3 glass which grants these properties.
