Volumetric Flask with Plastic Stopper 5 ml

A Volumetric Flask with a Plastic Stopper and 5 ml capacity is a precise laboratory glassware item designed for accurate preparation and measurement of chemical solutions. It is typically made from clear borosilicate glass, which is resistant to thermal shock and chemical corrosion. The flask has a pear-shaped body with a long narrow neck featuring a single calibration mark for exact volume measurement. The plastic stopper, usually made of polypropylene or LDPE, provides a secure closure to prevent contamination or evaporation of the contents.
