Pear Shaped Two-Neck Flask With 19/22 Outer Joints Capacity Of 200ml
Special Price $16.12 Regular Price $30.51
DESIGN---A pear-shaped flask is designed round at top but pointy at the bottom so a pipette can remove all the liquid,and allow recover much more material than in a round bottom flask.2 neck design with standard taper joints at top for easy assembly with other lab glass apparatus with standard taper joints.The extra neck can be used to fit a bleeding tube or thermometer adapter or additional funnel.It is usually with small size for small-scale distillations.
WHERE IS IT USED?----- Pear-shaped flasks can be used for both synthesis and evaporation,it is used for evaporating solutions to dryness post synthesis using a rotary evaporator.It can be used as both reaction flask and evaporation flask in organic chemistry.An example:it is used as a distillation flask in the small scale short path distillation apparatus attaching a short path distillation head.
DIMENSIONS-----The pear-shaped flask is with 24/40 joints,capacity of 200mL.
HEAVY WALL ---The pear-shaped flask is heavy-wall design , 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.
100% 40 DAY MONEY BACK GUARANTEE If you are not satisfied for any reason, simply return for a full refund, no questions asked. You have nothing to lose.Please also kindly undertand glassware is fragile, even if we pack them carefully,it may be broken during the shipment ,if you receive the items in broken status,don't hesitate to contact us ,we will arrange free replacement or full refund.

The pear shaped heavy wall flask are usually used for small-scale distillations.The pear shape allows recovery of more material than the same-scale round-bottomed flasks. With two necks having the same joints Laboy glass flasks are heavy wall designed,made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glasss 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.
