Glass Single Neck Flat Bottom Boiling Flask 250mL with 24/40 Joint Heavy Wall Receiving Apparatus Organic Chemistry Lab Glassware (Pack of 4)

DESIGN----The flat bottom flask is likely the round bottom flask but with a flat bottom allowing it standing up flat surface as the flask can sit upright on its own, rather than in a flask clamp or cork stand, ideal for using as a receiving flask.

When under heating, it is not durable as round bottom flask but better than Erlenmeyer flask which have the sharp and vulnerable corners.

The short neck is with a standard taper joint, which can attach the lab glassware with standard tape joint.

WIDELY USED-----A flat bottom flask is used in chemistry laboratory for experiments involving collecting and measuring liquids, mixing solvent In a apparatus, the flat bottom flasks can attach to a adapter, liebig or allhnn condenser, take off adapter as a or receiving flask.

In a soxhlet extraction, a flat bottom attaches the soxhlet extractor used as boiling and receiving flask.
