Glass Filtering Flasks
Filter material with ease with glass filtering flasks from USA Lab Equipment. Filtering flasks, also called vacuum flasks, suction flasks, or Büchner flasks, are used in various general laboratory applications for rapid filtration of liquids. We carry many filtering flasks sizes that are well suited for experiments of any proportion. Our smallest flask is designed to hold 1000 milliliters, while our largest flasks can hold up to 5000 milliliters. Like many other laboratory glassware products, our flasks are constructed with thick-walled borosilicate glass that is designed to remain intact while undergoing extreme temperature changes. What makes borosilicate glass so effective against cracking and shattering is that it contains boron trioxide, which allows for a very low coefficient of thermal expansion. Both durable and affordable, our glass filtering flasks will make the perfect addition to your laboratory equipment.
