Weighing Boats

A weighing boat holds your sample steady on the balance pan while you measure it out. This collection currently features a 50 ml polyethylene weighing tray, sized 44 x 44 mm and sold in packs of 10. It's a single use item that schools and labs go through quickly, so it's worth keeping a spare pack on hand. Ships nationwide from our Boksburg warehouse.

How to choose the right weighing boat

  • Match the tray size to your balance pan. A 44 x 44 mm tray suits small pans and micro samples.
  • Choose polyethylene for aqueous and powder samples. It resists most common lab chemicals.
  • Buy in packs. These are single use and get discarded after each weighing.
  • For larger samples or different pan sizes, browse our full Weighing & Measurement range.

Common uses

  • Weighing powders, granules, and liquids before a titration or reaction
  • Portioning reagents for practical chemistry classes
  • Taring a balance for tablet or capsule counts in pharmacy training
  • Quick, disposable weighing where a permanent dish isn't practical

What is a weighing boat?

A weighing boat is a small, lightweight plastic tray used to hold powders, granules or liquids while they are weighed on a balance, protecting the pan from spills and contamination. Their folded or moulded shape makes it easy to pour the contents out afterward.

SmartLabs stocks weighing boats in the standard sizes used for everyday reagent and sample weighing across schools and labs.

Common uses of weighing boats in the lab

Where weighing boats do the heavy lifting.

  • Powder & Reagent Weighing

    A weighing boat keeps powders contained and off the balance pan for a clean, accurate reading.

  • Sample Transfer

    The folded shape makes it easy to pour a weighed sample straight into a flask or container.

  • Classroom Practicals

    Disposable weighing boats speed up cleanup between student groups in a busy practical session.

  • Preventing Contamination

    Using a fresh boat for each sample avoids cross contamination between different reagents.
