Lab Flasks
Volumetric flasks, prized for their accuracy in measuring liquid volumes, are a highlight of this category, crucial for quantitative analyses. Boiling flasks, with their round bodies and narrow necks, facilitate even heating and are essential in distillation and boiling processes. Neck filtration flasks are designed for vacuum filtration, combining durability with functionality for precise separation tasks.
The round, bottom-angled three-neck flasks stand out for their adaptability in complex chemical reactions, allowing simultaneous inputs or outputs. Also, baffled flasks enhance the mixing and oxygen transfer in biological cultures with their unique design.
Each type of lab flask, from glass flasks with stoppers to volumetric flasks, plays a pivotal role in lab efficiency and accuracy. This extensive range of lab flasks enhances experimental capabilities and encourages exploration and innovation in laboratory settings.
