Working Principle:
The flask measures the displacement of liquid when cement or fine powder is introduced. The change in liquid level is used to calculate the specific gravity of the material accurately.
Robust Borosilicate ConstructionManufactured from high-quality borosilicate glass, the Le Chatelier Flask combines excellent chemical resistance with superior clarity. It remains inert to a wide range of chemicals and tolerates temperatures up to 400C, making it dependable for repeated laboratory use and cleaning.
Precise Graduations for Accurate MeasurementsThe flask features distinct graduation markings at every 0.1 ml interval between 0 and 24 ml, enabling exceptionally accurate volume readings. This level of precision is essential for testing the specific gravity of hydraulic cements and lime to meet industry standards.
User-focused Design for Laboratory ApplicationsDesigned for tabletop use, the flask's conical bulb provides stability during manual testing procedures. The standard neck accommodates ground glass stoppers for secure sealing, and the flask's transparency ensures easy observation of contents, facilitating immediate, manual reading during tests.
FAQ's of 24ml Le Chatelier Flask:
Q: How is the 24ml Le Chatelier Flask used for specific gravity determination?
