Volumetric Flask with Plastic Stopper 25 ml

A Volumetric Flask with a Plastic Stopper and 25 ml capacity is a high-precision laboratory glassware used for preparing and measuring accurate liquid volumes. Made from clear borosilicate glass, it meets ISO 1042 and DIN 12664 standards, ensuring high chemical and thermal resistance. The flask features a pear-shaped body with a flat bottom for stability and a long narrow neck with a single calibration mark for exact volume measurement. The plastic stopper, typically made of polypropylene or LDPE, offers a secure seal to prevent contamination and evaporation.
