Introducing our Class A Borosilicate 3.3 Volumetric Flask with a generous capacity of 500ml. This volumetric flask is specifically designed for precise volumetric measurements in laboratory applications. It is made from high-quality 3.3 borosilicate glass, ensuring superior chemical durability and resistance to thermal shocks. The flask features a low temperature gradient, enabling it to withstand high temperatures without compromising accuracy. It comes with a polyethylene (PE) stopper, size 19/26, providing a secure seal for your samples. The flask is equipped with a single etched graduation mark and blue print, allowing for easy and precise volume readings. With a tolerance of ±0.250ml, this flask guarantees reliable and accurate results. Standing at a height of 260mm, it offers ample capacity for your volumetric needs. The flask is also autoclavable at 121°C, facilitating efficient sterilization. Complying with ISO 1042 standards, this Class A volumetric flask is the ideal choice for precise volumetric measurements in laboratory settings where accuracy and durability are paramount.
