Medium-sized polystyrene weigh boats designed for accurate weighing and sample handling in laboratory environments. These 85x85mm weigh boats feature an anti-static surface treatment that minimizes particle attraction and sample loss during weighing procedures. The smooth, non-stick interior surface ensures complete sample transfer and easy cleaning between uses.
Constructed from chemically resistant polystyrene, these weigh boats provide a stable platform for weighing powders, granules, and liquid samples. The medium size accommodates sample volumes typically used in analytical chemistry, pharmaceutical testing, and research applications where precise mass measurements are required.
How It Works
Weigh boats function as temporary sample containers that provide a clean, stable surface for analytical balance measurements. The polystyrene construction offers chemical inertness to most laboratory solvents and reagents, preventing sample contamination or boat degradation during weighing procedures.
The anti-static treatment reduces electrostatic charge buildup that can attract airborne particles or cause sample adhesion to the boat surface. This treatment ensures accurate mass measurements by minimizing weighing errors caused by static electricity, particularly important when working with fine powders or low-mass samples.
The smooth interior surface minimizes sample retention, allowing for quantitative transfer of weighed materials to reaction vessels or analytical instruments. The boat's rigid structure maintains shape stability under typical laboratory conditions, preventing deformation that could affect measurement accuracy.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Material Construction | Anti-static polystyrene with smooth surface | Standard polystyrene or aluminum without anti-static treatment | Reduces weighing errors from static attraction and improves sample transfer efficiency |
| Size Dimensions | 85x85mm medium format | Smaller boats around 60x60mm or larger 100x100mm options | Optimal size for typical analytical samples while fitting standard balance chambers |
| Surface Treatment | Non-stick smooth interior | Standard molded surface without specialized treatment | Ensures quantitative sample recovery and reduces cleaning between uses |
| Package Quantity | 500 boats per package | Varies from 250-1000 boats per package | Balanced quantity for medium-throughput laboratories without excessive inventory |
These weigh boats combine anti-static treatment with optimal sizing for analytical weighing applications. The polystyrene construction and smooth surface treatment provide reliable performance for quantitative sample handling and transfer procedures.
Practical Tips
Tare each boat individually as slight mass variations between boats can affect measurement accuracy.
Why: Manufacturing tolerances mean each boat may have slightly different mass.
Store weigh boats in a controlled humidity environment around 45-55% relative humidity.
Why: Proper humidity levels minimize static charge buildup and improve weighing reproducibility.
Use the boat edges to create a controlled pour spout for precise sample transfer.
Why: The flexible edges can be shaped to direct sample flow and prevent spillage.
Use fresh boats for each different sample type, even when working with similar materials.
Why: Cross-contamination can occur even with visually clean boats and affect analytical results.
Allow boats to equilibrate to balance chamber temperature for 2-3 minutes before critical measurements.
Why: Temperature differences can create air currents that affect measurement stability.
Keep unused boats in original packaging away from direct sunlight and heat sources.
Why: UV exposure and heat can degrade polystyrene and reduce anti-static effectiveness.
Check boats for cracks or deformation before use, especially when working with valuable samples.
Why: Damaged boats can lead to sample loss or affect weighing accuracy.

Compliance
What is the chemical compatibility of these weigh boats with organic solvents?
Polystyrene construction provides resistance to most aqueous solutions and polar solvents. Consult chemical compatibility charts for specific organic solvents, as some may cause swelling or dissolution.
How effective is the anti-static treatment for weighing hygroscopic materials?
The anti-static surface reduces particle attraction, but hygroscopic materials may still require controlled humidity conditions and rapid weighing to prevent moisture absorption.
What is the maximum sample mass these boats can safely hold?
Consult product datasheet for load specifications. The 85x85mm size typically accommodates several grams of material depending on bulk density and handling requirements.
Can these weigh boats be used with heated samples or in elevated temperature conditions?
Polystyrene has limited thermal resistance. Allow samples to cool to room temperature before weighing to prevent boat deformation and measurement errors.
How do I minimize static charge when working with very fine powders?
Use an ionizing air gun near the balance, maintain consistent laboratory humidity around 45-55%, and allow boats to equilibrate before use.
Are these boats suitable for microanalytical applications requiring sub-milligram accuracy?
Yes, the smooth surface and anti-static treatment support accurate measurements at the sub-milligram level when used with appropriate analytical balances.
What is the shelf life of these weigh boats?
Polystyrene boats have indefinite shelf life when stored in dry conditions away from UV light and extreme temperatures.
