500ml Borosilicate Glass Volumetric Flask with Plastic Stopper

500ml Borosilicate Glass Volumetric Flask with Plastic Stopper

The Eisco Labglass 500 mL volumetric flask delivers precision for the preparation and dilution of larger solution volumes. Its clear borosilicate body and narrow neck make filling and reading straightforward whilst supporting controlled handling during measurement.

Manufactured from Borosilicate Glass 3.3, the flask withstands repeated heating, cleaning and exposure to laboratory reagents without loss of clarity or form. Uniform walls promote even heat transfer, and a low temperature gradient supports stability across temperature changes to help maintain calibration accuracy. Each flask is individually calibrated to contain (TC, In) at 20 °C and marked with a fine, permanent graduation line for precise measurement. The fitted polyethylene stopper provides a tight, chemical-resistant seal that prevents contamination or evaporation. Mechanically strong and thermally stable, it performs reliably in both laboratory and production environments.
