These Standard Weighing Boats are made from flexible polystyrene, offering a smooth surface for accurate pour-outs with minimal sample loss. They are designed for use in laboratory environments and are ideal for measuring and transferring various substances. The shallow, wide-bottomed design prevents tipping, and the rounded corners simplify sample transfer. These boats are biologically inert, resistant to weak acids, alcohols, bases, and aqueous solutions, making them a reliable choice for many applications. They are also FDA and food-grade compliant.
