pumpflask

A pumpflask is a type of container designed for dispensing liquids, often used in laboratories and for various industrial applications. Its primary distinguishing feature is the integrated pump mechanism that allows for controlled and often pressurized dispensing of the contents.

The pump mechanism can vary in design. Some pumpflasks utilize a manual hand pump, requiring the user to operate a lever or plunger to generate pressure and force the liquid out through a spout or nozzle. Other designs might incorporate a more automated pumping system, potentially powered by electricity or compressed air, for higher throughput or more precise dispensing.

The construction materials for pumpflasks are chosen based on the intended use and the type of liquid being handled. Common materials include glass, various types of plastic, and stainless steel. These materials are selected for their chemical resistance, durability, and ability to withstand the pressures generated by the pump.

Pumpflasks find application in a range of fields. In laboratories, they are used for transferring solvents, reagents, and other chemicals accurately and safely, minimizing exposure and spills. Industrially, they can be employed for dispensing lubricants, cleaning agents, or other fluids in manufacturing processes. The ability to control the flow rate and volume dispensed makes pumpflasks a valuable tool for tasks requiring precision.
