Volumetric Flasks with Glass Stopper, Accuracy as per Class A. these flasks are widely used in laboratories for precise dilutions and preparation of standard solutions. 

* Glass Material: made from borosilicate glass, offer exceptional chemical and heat resistance. 

* calibration clarity: Volumetric flasks are calibrated to contain a precise volume at a particular temperature. Easy to read scale and large labeling field for easy marking. The volumetric accuracy is maintained as per high quality standards. 

* Solid Glass Stopper : The glass stopper is a type of cap made of glass that fits snugly onto the neck of the flask, provides a secure seal, preventing evaporation and contamination, and making it ideal for storing and transporting liquids 

* Important Notes: To ensure a long service life for your volumetric glassware and to exclude possible volume changes, these glass products should not be heated above + 250°C in drying cabinets or sterilisers
