Pour-boat weighing dishes by Heathrow Scientific have a pour spout design that easily dispenses samples without flexing the dish. Dishes are made from 12mil thick polystyrene for better strength, stability, and handling. Flat-bottom dishes are biologically inert and resistant to dilute and weak acids, aqueous solutions, alcohols, and bases. Resist temperatures to 158 degree F (70 degree C). Weighing dishes can be used with microwave moisture analyzers and are food-grade compliant. The weighboats are disposable.Measures 108 mm length by 183 mm width by 26 mm depth. White. 500/pk.
