Round Bottom Flask 50ml
A 50ml round-bottom flask (RBF) is a crucial borosilicate glass laboratory vessel designed for small-scale, uniform heating, boiling, and distillation of liquids. Its spherical shape, ideal for magnetic stirring and precise chemical reactions, is commonly used in reflux setups, rotary evaporators, and vacuum applications.
Round Bottom Flask 50ml
Key Uses and Features:
Uniform Heating: The shape allows for even heat distribution, preventing hot spots and reducing risk of breakage.
Distillation & Reflux: Used as a reaction vessel for heating and as a boiling/receiving flask in distillation setups.
Small-Scale Reactions: Ideal for containing chemical reactions, especially when a vacuum or inert atmosphere is needed.
Rotary Evaporation: Used to efficiently evaporate solvents.
Temperature Control: Fits perfectly into heating mantles or oil/water baths for stable, consistent temperatures.
Secure Sealing: The narrow, ground-glass neck fits standard condensers, stoppers, and thermometers.
These flasks require a cork ring or clamp for support when in use. Round Bottom Flask 50ml
Common Applications
Chemical Reactions: It serves as the primary vessel for various chemical reactions, especially in organic synthesis, due to its ability to withstand heating and facilitate mixing.
Reflux Setups: The flask is ideal for heating a reaction mixture for prolonged periods without solvent loss, as a condenser can be securely attached to its neck to return condensed vapors to the flask.
Distillation: In distillation processes (simple or fractional), the 50 mL round bottom flask can function as the boiling flask to heat the liquid mixture or as the receiving flask to collect the condensed distillate.
Rotary Evaporators (Rotovaps): This size flask is commonly used with a rotary evaporator to efficiently remove solvents from a solution under reduced pressure, as its shape is well-suited for rotation and even evaporation.
Solution Preparation and Dissolving: The round bottom design and heat resistance make it suitable for preparing solutions, dissolving solids into liquids, especially when heating or agitation is required.
Vacuum Applications: The spherical design helps to distribute stress evenly across the glass surface, making the flask more resistant to the pressure differentials encountered in vacuum applications.
Sample Preparation: Due to its small, compact size, it is particularly suitable for small-scale reactions and sample preparation in chemistry and biology research.
