1000ml Borosilicate Glass Volumetric Flask with Plastic Stopper
The Eisco Labglass 1000 mL volumetric flask delivers precision for large-volume solution preparation and dilution. Its clear borosilicate body and narrow neck make pouring and reading simple whilst ensuring controlled handling during measurement.
Manufactured from Borosilicate Glass 3.3, the flask endures regular heating, cleaning and exposure to reagents without loss of clarity or strength. Uniform walls support even heat distribution, and a low temperature gradient helps maintain calibration accuracy across temperature variations. Each flask is individually calibrated to contain (TC, In) at 20 °C and marked with a fine, permanent graduation line for accurate solution measurement. The fitted polyethylene stopper forms a secure, chemical-resistant seal that prevents contamination or evaporation. Mechanically strong and thermally stable, it performs dependably in daily laboratory or production use.
