TWO-NECK FLAT BOTTOM BOILING FLASK
The flat bottom flask with two necks is likely the other round bottom flask but with a flat bottom allowing it standing up flat surface as the flask can sit upright on its own. With 24/40 glass ground taper joint. It can be used in heating during distillation, they are not as durable as round bottom flasks for heating better than Erlenmeyer flask which has have the sharp and vulnerable corners .
- DESIGN----This is a boiling flask designed with flat bottom,with 2 neck featured by two standard taper 24/40 outer joints.It is likely the 2 neck 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..The short neck is with two standard taper joint,which can attach the lab glassware with standard tape joints.
- USE-----A flat bottom flask is used in chemistry laboratory for experiments involving collecting and measuring liquids, mixing solvent In a distillation apparatus,the flat bottom flasks can attach to a distillation adapter,liebig or allhnn condenser,take off adapter as a distillation or receiving flask. With two necks,it allows attaching one more glassware parts in the reaction or distillation,for example,it is ideal to fit a magnetic stirrer shaft for Stirring solvent.
- DIMENSIONS-----The short neck is with two 24/40 standard taper outer joints, which is interchangeable ,can be attached to any jointed glassware with a 24/40 male joint.
- HEAVY WALL ---This vauum gas manifold is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable.
