Description
Dropping funnel, cylindrical, with pressure-equalising tube, graduated, PTFE stopcock, 50 ml is a compact laboratory dosing funnel for controlled reagent addition under equalised pressure. It is manufactured from heat-resistant, durable borosilicate glass and carries body graduations printed to ISO 4800. The integrated pressure-equalising tube supports smooth delivery when the receiving vessel is closed or under reduced pressure. Thick walls and a reinforced rim help limit breakage during washing and transport, while perfectly ground NS necks with smooth interiors follow DIN standard 12242. Quantity divisions and inscriptions are applied in white enamel for clear, lasting readability. Supplied with a PE stopper and an interchangeable stopcock that needs no lubrication, the funnel from manufacturer ISOLAB Laborgeräte is well suited to small-scale synthesis, titrations and preparative work. The cylindrical 50 ml format offers practical handling on the bench where precise volume control and reliable joints are essential for routine laboratory dosing applications.
