25ml Borosilicate Glass Volumetric Flask with Plastic Stopper
The Eisco Labglass 25 mL volumetric flask delivers precision in routine solution preparation and dilution. Its clear borosilicate body and narrow neck make filling and reading simple whilst supporting controlled handling during regular laboratory work.
Manufactured from Borosilicate Glass 3.3, the flask withstands repeated heating, cleaning and exposure to chemical reagents. Uniform walls provide even heat distribution, aided by a low temperature gradient that helps preserve calibration accuracy under varying temperatures. Each flask is individually calibrated to contain (TC, In) at 20 °C and marked with a sharp, single graduation line for accurate measurement. The fitted polyethylene stopper provides a tight, chemical-resistant seal to prevent contamination or evaporation. Mechanically strong and thermally stable, it performs consistently across daily analytical and laboratory environments.
