50ml Borosilicate Glass Volumetric Flask with Plastic Stopper
The Eisco Labglass 50 mL volumetric flask provides precision for routine preparation and dilution of laboratory solutions. Its clear borosilicate body and narrow neck make filling, reading and handling straightforward whilst helping maintain control during everyday analytical tasks.
Manufactured from Borosilicate Glass 3.3, the flask resists heat, chemical exposure and repeated cleaning without loss of clarity. Uniform walls ensure even thermal response, aided by a low temperature gradient that helps maintain calibration accuracy through temperature variations. Each flask is individually calibrated to contain (TC, In) at 20 °C and marked with a fine single graduation line for precise measurement. The fitted polyethylene stopper provides a secure, chemical-resistant seal that prevents contamination or evaporation. Mechanically strong and thermally stable, it performs consistently under daily laboratory conditions.
