Key function of a weigh boat is to provide a temporary container to accurately hold and transfer small quantities of various laboratory chemicals, keeping the working area tidy and protecting analytical balances. The affordability and disposability makes them a versatile laboratory tool.
A weigh boat, also known as a weigh dish or weighing boat, is a small boat-shaped container used in chemistry labs and other settings to measure out small quantities of materials.
Some key uses of weigh boats include…

1. Weighing Out Samples
They provide a convenient vessel for accurately weighing out small amounts of powders, liquids, or other materials using an analytical balance. The measured material can then be easily poured out of the weigh boat for further use.
2. Containing Spills
The lip around the perimeter of the weigh boat helps contain any spills or leakage of chemicals inside it, preventing contamination of the balance, lab bench, or other surfaces. This also facilitates safer and easier transport of measured chemicals.
3. Disposability
Weigh boats are generally disposable, so chemicals and residues can simply be discarded with the weigh boat after use rather than needing to be cleaned out between uses. This saves time and effort.
4. Material Compatibility
Weigh boats come in a range of materials like plastic, aluminum, and ceramic that resist reaction with or absorption of many common laboratory chemicals. Appropriate material choice helps preserve sample integrity.
