Heathrow Scientific Standard Square Weighing Boats are disposable polystyrene boats designed for accurate sample measurement of powders, granules, and small liquid volumes. Smooth, flat interiors and an easy-pour spout help transfer weighed material cleanly into tubes, flasks, or reaction vessels with minimal sample loss.
This listing is for the white version sold in a pack of 500—ideal for routine balance work, teaching labs, and sample-prep benches.
Features and Benefits
FDA / food-grade compliant polystyrene for routine lab handling.
Biologically inert and resistant to dilute acids, alcohols, and bases.
Shallow design with a wide, flat bottom to resist tipping on balance pans.
Rounded corners simplify transfer and reduce residue traps.
Disposable and stackable to keep benches organized.
