These weighing boats are a good addition to our white flexible boats. Both flexible boats have smooth surfaces to provide accurate pour-outs with minimal sample loss. These polystyrene boats have a shallow shape with a wide, flat bottom to resist tipping. Rounded corners simplify transfer. Biologically inert and resistant to dilute and weak acids, aqueous solutions, alcohols, and bases. May be used with microwave moisture analyzers. Resist temperatures to 200 °F / 93 °C.
