Conical Jar (Erlenmeyer) 250 ml
Conical Jar (Erlenmeyer) 250 ml (Product Code: SCI-665/081) is a 250 ml graduated conical flask of borosilicate glass used for mixing, heating, dissolving and filtering liquids in general chemistry, biology and microbiology work. This general-purpose capacity handles recrystallisation, larger titration aliquots and collecting filtrate beneath a funnel, and the narrow mouth takes a stopper or cotton plug. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of chemistry lab glassware in India, at its own factory in Ambala.

What Is the 250 ml Conical Flask Used For?
Common tasks include recrystallising a solid (dissolve it hot, then let it cool slowly in the flask), collecting filtrate from a glass funnel resting in the narrow mouth, preparing broths or media in microbiology, and swirling reaction mixtures that would splash out of a beaker.
When heating the 250 ml conical flask on a hot plate, leave the neck unstoppered so pressure cannot build up, and handle the warm flask with tongs or a heat-resistant glove. The sloping sides also make it easy to pour the contents out cleanly.
OEM Manufacturer
The 250 ml conical flask is produced by Jain Scientific Equipments Private Limited — trading as ScienceLab — as the OEM (original equipment manufacturer), at its own licensed factory at Saha, Ambala, Haryana, India. The company sells it factory-direct to schools, colleges, laboratories, dealers and importers rather than through a trading chain.
Replacement flasks and repeat orders for the same code are organised by the manufacturer itself — ask us. The ScienceLab profile gives an overview of the company.
