Volumetric Flask 3.3 Boro Glass Class A Volumetric Flasks Ground Stopper Flat Bottom 5ml 10ml 20ml 25ml 50ml 100ml 200ml 250ml 500ml 1000ml 2000ml (500ml)

A volumetric flask is an accurate instrument for formulating a precise concentration of a certain substance in a solution. The volume bottle is marked with: temperature, capacity, scale line. There is a scale on the bottleneck of the capacity, which means that when the liquid liquid's concave surface is tangent to the capacity bottleneck's mark at the indicated temperature, the solution volume is exactly equal to the volume marked on the bottle. There are many sizes of flasks, 5ml, 10ml, 20ml, 25ml, 50ml, 100ml, and 200ml, 250ml, 500ml, 1000ml, 2000ml. Material: 3.3 Boro Glass Capacity: 5ml, 10ml, 20ml, 25ml, 50ml, 100ml, and 200ml, 250ml, 500ml, 1000ml, 2000ml Specification parameters: specific parameters as shown in the dimension drawing Number of Items: 1 Features: 1. The total amount of solvent should not exceed the mark of the volumetric flask. Once it exceeds the limit, it must be reconfigured. 2. The volumetric flask can not be heated. If the solute is exothermic during the dissolution process, it must be cooled after the solution is cooled. Because the temperature will increase, the bottle will swell and the volume will be inaccurate. 3. The volumetric flask can only be used to configure the solution, and it cannot be stored for a long time or for a long period of time because the solution may corrode the bottle body and affect the accuracy of the volumetric flask. 4.
