Eisco 25 mL Borosilicate Glass Volumetric Flask

ELabGlass® 25 mL volumetric flasks from Eisco are manufactured using state-of-the-art glass blowing and calibration techniques to the tightest tolerances. All volumetric flasks are made with high quality, low expansion borosilicate 3.3 glass which makes less susceptible to breakage from thermal shocks and exposure to higher temperatures allowing them to be autoclaved up to 121° C. ELabGlass® is highly resistant to water, neutral and acid solutions, concentrated acids, chlorine, bromine iodine and organic matter.
