5ml Borosilicate Glass Volumetric Flask with Plastic Stopper
The Eisco Labglass 5 mL volumetric flask provides precision in small-scale solution preparation. Its clear borosilicate body and narrow neck make filling and reading straightforward whilst supporting careful handling of micro-volume samples.
Manufactured from Borosilicate Glass 3.3, the flask withstands regular heating, cleaning and contact with laboratory reagents. Uniform walls promote even thermal response, aided by a low temperature gradient that helps maintain calibration accuracy during use. Each flask is individually calibrated to contain (TC, In) at 20 °C and marked with a sharp single graduation line for controlled measurement. The fitted polyethylene stopper forms a secure, chemical-resistant seal to protect prepared solutions from contamination or evaporation. Mechanically strong and stable during routine handling, it performs consistently across daily laboratory tasks.
