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.

&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.

Weighing Dishes

<h2 data-section-id="1dr6xip" data-start="0" data-end="41">What Are Laboratory Weighing Dishes?</h2>
&nbsp;
Laboratory weighing dishes (also called weigh boats or pour boats) are shallow, flat-bottomed, flexible disposable containers molded from a special grade of antistatic polystyrene (PS), rated from &minus;10&deg;C to +80&deg;C, used to hold solid or liquid samples on an analytical or top-loading balance pan during mass measurement. After weighing, the flexible PS walls are bent to form a pour spout for transferring the sample into a flask, beaker, or tube with minimal loss. Globe Scientific antistatic PS weighing dishes are ISO 9001:2015 certified, contaminant-free, biologically inert, and resistant to dilute acids, aqueous solutions, alcohols, and bases, available in square, hexagonal, and pour-boat styles at capacities from 10 mL to 350 mL. Weighing dishes are single-use disposables: washing removes the antistatic treatment. Choose black dishes for light-colored samples and white dishes for dark or colored samples.

&nbsp;
Shape
Square dishes with smooth sloping sides and recessed rounded corners provide clean pour-outs with minimal retained sample&mdash;the standard choice for most powder and liquid weighing. Hexagonal dishes have a six-sided profile that resists sliding on balance pans and provides a positive grip point during transfer; the molded perimeter adds stability for larger sample masses. Pour-boat dishes have a molded spout for precise dispensing of liquid or gel-like samples into vessels after weighing.
Capacity
Use 10&ndash;20 mL square dishes for micro-scale weighing under 2 g (reagents, standards, APIs) on analytical balances with 0.1 mg readability. Use 50&ndash;100 mL for preparative weighing of 2&ndash;20 g on top-loading analytical balances. Use 200&ndash;350 mL for large-sample or bulk-powder weighing requiring a wide base to fit the balance pan.
Color
White dishes are the default for most applications. Black dishes in 10 mL square format improve visibility of white, cream, or fluorescent powders&mdash;confirming that all sample material has been transferred before recording the net weight. Both colors resist the same chemical exposure and have identical material specifications.
Temperature Range
Antistatic PS is rated to +80&deg;C, covering all ambient and moderate-warm sample conditions. For moisture determination at 105&deg;C (oven drying) or incineration applications, aluminum weighing dishes are the correct format&mdash;polystyrene will deform above 80&deg;C.

&nbsp;
Globe Scientific antistatic polystyrene weighing dishes are manufactured from a specialized PS formulation that provides controlled antistatic behavior, distinguishing them from standard polystyrene labware. Larger formats typically use a wall thickness of approximately 12 mil (&asymp;0.3 mm) to maintain structural rigidity on balance pans during weighing. As of 2026, 20 mL and 100 mL square weighing dishes are the most commonly stocked formats in pharmaceutical QC and academic analytical chemistry laboratories due to their versatility across micro and preparative weighing workflows. In addition to weighing applications, these dishes are also commonly used as temporary trays for snap-freezing small samples on dry ice during preparation steps.
