Volumetric Flask 50ml Borosilicate Glass Class A Precision ISO 1042

Volumetric 50ml Borosilicate 3.3 Glass Flask with Class A Accuracy TN LAB 50 ml Volumetric Borosilicate Glass Flask Class A Precision   50ml Class A Accuracy, +/- 0.05ml @20C, per ISO 1042-1998 Glass flask with NS 12/21 joint for superior strength and durability PTFE 12/21 stopper to minimize sticking and seizing Easy-to-read precise 50ml marking Flat bottoms are ideal for precise stirring Excellent chemical resistance Volumetric Flask Applications A volumetric flask is used to determine the precise and exact volume of solution Volumetric flasks measure one exact liquid volume. This 50ml volumetric flask will measure 50ml with Class A accuracy. In the neck of all volumetric flasks is a very thin line, the graduation line, indicating the fill point. A volumetric flask will only measure its designed volume. No other graduations or volume markings appear other than the graduation line. A volumetric flask is more accurate than a graduated measuring cylinder, but can only be used to measure one volume, determined by the graduation ring
