Weighing Dishes & Boats

<h2 data-section-id="4vlupf" data-start="410" data-end="461">What Are Laboratory Weighing Dishes and Funnels?</h2>
&nbsp;
Laboratory weighing dishes and funnels are disposable antistatic consumables used in gravimetric sample preparation&mdash;where solid or liquid materials are weighed on analytical or top-loading balances before being transferred into reaction vessels, volumetric flasks, or tubes. Weighing dishes (also called weigh boats or pour boats) are flat-bottomed antistatic polystyrene containers used to hold samples on the balance pan during weighing. Weighing funnels are antistatic polypropylene tools with one flat side for stability on the balance and a conical stem designed to fit flask necks, allowing complete quantitative transfer of material with minimal loss. Globe Scientific offers antistatic PS weighing dishes in square, hexagonal, and pour-boat formats ranging from 10 mL to 350 mL, and antistatic PP weighing funnels in extra-small through extra-extra-large sizes. Both are single-use only because washing removes antistatic properties and affects weighing accuracy.

<h2 data-section-id="1yz3s79" data-start="1436" data-end="1480">How to Choose Weighing Dishes and Funnels</h2>
&nbsp;
Weighing Dish Shape
Square weigh boats are used for routine laboratory weighing and are designed with sloping sides and recessed corners to minimize sample loss during transfer. Hexagonal weigh boats provide better stability on balance pans due to their molded edges and also offer improved grip during handling, making them suitable for workflows where stability matters. Pour-boat designs include a built-in spout that allows controlled and accurate dispensing of liquids or viscous samples into receiving vessels without spillage.
Weighing Dish Capacity
Small 10&ndash;20 mL dishes are used for micro-scale weighing of reagents typically under 2 g on analytical balances. Medium 50&ndash;100 mL dishes are used for routine laboratory weighing of 2&ndash;20 g samples. Large 200&ndash;350 mL dishes are used for bulk powders and higher-volume transfers on top-loading balances.
Weighing Funnel Size
Extra-small funnels are used for 5&ndash;20 mL vessels and microtubes, small funnels for 20&ndash;50 mL, medium funnels for 50&ndash;200 mL, large funnels for 200&ndash;500 mL, and extra-large funnels for 500&ndash;1000 mL flasks. The flat side ensures stable placement on the balance pan during weighing before transfer.
Color: White vs. Black
White dishes provide high contrast for dark or strongly colored samples, making them easier to visualize during transfer. Black dishes are used for light-colored or transparent samples where residue visibility is important, especially when confirming complete sample recovery.

&nbsp;
Globe Scientific antistatic polystyrene weighing dishes operate within &minus;10&deg;C to +80&deg;C and resist dilute acids, bases, and alcohols. The antistatic formulation is a specialized grade designed to reduce static charge and prevent sample loss during weighing and cannot be replaced with standard polystyrene labware. As of 2026, 20 mL and 100 mL antistatic weigh boats are widely used in pharmaceutical QC laboratories, research facilities, and academic analytical chemistry workflows where accuracy and contamination-free handling are required.
