Large anti-static polystyrene weigh boats designed for precise sample measurement and transfer in laboratory environments. These 140x140mm weigh boats provide a stable, static-free platform for weighing powders, crystals, and other solid materials on analytical and precision balances.
The anti-static polystyrene construction prevents sample loss due to electrostatic charge buildup, ensuring accurate mass determination. The large surface area accommodates substantial sample volumes while maintaining easy handling and pouring characteristics for quantitative transfer operations.
How It Works
The weigh boats function as temporary sample containers that provide a stable, contamination-free surface for mass measurement operations. The polystyrene material offers chemical inertness and dimensional stability under typical laboratory conditions, ensuring consistent weighing performance.
Anti-static treatment of the polystyrene surface prevents electrostatic charge accumulation during sample handling. This eliminates sample adhesion to container walls and reduces measurement errors caused by electrostatic forces interfering with balance operation. The smooth surface finish facilitates complete sample transfer and minimizes residual material retention.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Surface Area | 140x140mm large format | Smaller models typically offer 50x50mm to 100x100mm dimensions | Accommodates larger sample volumes and provides more stable platform for precision weighing |
| Anti-Static Treatment | Anti-static polystyrene construction | Basic polystyrene may lack anti-static properties | Reduces sample loss and measurement errors caused by electrostatic charge buildup |
| Material Quality | Laboratory-grade polystyrene | Industrial-grade plastics may have higher impurity levels | Ensures chemical inertness and prevents sample contamination in analytical applications |
| Pack Size | 500-count package | Varies by model and supplier | Bulk packaging reduces per-unit cost and restocking frequency for high-volume laboratories |
These large weigh boats provide expanded surface area with anti-static properties in a bulk pack format suitable for laboratories requiring frequent sample weighing operations.
Practical Tips
Allow weigh boats to equilibrate to room temperature before use, especially when stored in different environmental conditions.
Why: Temperature differences can affect material dimensions and static charge accumulation.
Use dedicated spatulas or microspatulas to avoid cross-contamination when transferring samples between boats.
Why: Prevents analytical interference and maintains sample purity throughout weighing procedures.
Store unused weigh boats in their original packaging or covered containers to prevent dust accumulation.
Why: Maintains clean surfaces and prevents contamination that could affect weighing accuracy.
Dispose of weigh boats containing hazardous materials according to institutional waste management protocols.
Why: Ensures proper handling of contaminated laboratory plasticware and regulatory compliance.
Record the lot number and manufacturer date when documentation is required for critical measurements.
Why: Provides traceability for quality control and method validation purposes.
If samples appear to stick to the boat surface, check humidity levels and consider using different material types for problematic compounds.
Why: Low humidity can increase static charge buildup despite anti-static treatment.

Compliance
What is the maximum sample capacity for these weigh boats?
The 140x140mm surface area can accommodate several grams of powder or granular material, with exact capacity depending on sample density and particle characteristics. Consult product datasheet for specific volume specifications.
Are these weigh boats compatible with organic solvents?
Polystyrene shows good compatibility with most aqueous solutions and mild organic solvents, but may be affected by aromatic hydrocarbons and chlorinated solvents. Test compatibility with specific solvents before critical applications.
How effective is the anti-static treatment?
The anti-static treatment significantly reduces electrostatic charge buildup compared to untreated plasticware, but performance may vary with humidity conditions and sample properties.
Can these weigh boats be used at elevated temperatures?
Polystyrene begins to soften around 80-100°C. These weigh boats are designed for ambient laboratory conditions and should not be used in heated applications.
What is the weighing precision achievable with these boats?
Weighing precision depends on the balance used and environmental conditions. The lightweight, stable design supports accurate measurements on analytical balances with 0.1mg readability.
How should these weigh boats be disposed of after use?
Dispose according to local regulations for laboratory plasticware. Boats contaminated with hazardous materials require appropriate waste stream classification.
