| Automation Level | manual |
Small polystyrene weigh boats designed for precise sample handling in laboratory environments. These 46x46mm vessels feature anti-static construction to prevent particle adhesion and electrostatic discharge during sensitive weighing operations. The smooth, non-stick polystyrene surface enables complete sample recovery and minimizes material loss during transfer procedures.
The compact square design provides optimal balance between surface area and workspace efficiency. Anti-static properties prevent interference with analytical balance performance and reduce contamination risk in controlled environments. These disposable vessels eliminate cross-contamination concerns while maintaining measurement accuracy for gravimetric analyses across diverse sample types.
How It Works
Weigh boats function as temporary sample containers that isolate materials from direct contact with analytical balance pans. The polystyrene construction provides chemical inertness for most laboratory reagents while maintaining dimensional stability under standard laboratory conditions. The smooth surface finish minimizes sample adhesion through reduced surface roughness and optimized contact angles.
Anti-static treatment prevents electrostatic charge accumulation that could interfere with sensitive analytical balances or cause sample loss through electrostatic attraction. The material's low density and uniform thickness ensure minimal tare weight contribution while providing sufficient structural integrity for sample manipulation. The square geometry maximizes usable surface area within the specified footprint while providing stable positioning on balance pans.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Material Construction | Anti-static polystyrene with smooth non-stick surface | Standard polystyrene or aluminum without anti-static treatment | Reduces measurement errors from static interference and improves sample recovery completeness |
| Surface Finish | Smooth non-stick surface for complete sample recovery | Standard polystyrene surfaces may retain sample residue | Enables quantitative transfer with minimal material loss in analytical procedures |
| Geometry Design | 46x46mm square configuration | Diamond or hexagonal shapes with less usable area | Maximizes effective surface area while maintaining balance pan compatibility |
| Packaging Quantity | 500 boats per package | Varies by manufacturer from 250-1000 per package | Provides convenient inventory size for routine laboratory use without excessive storage requirements |
These weigh boats combine anti-static properties with optimized geometry for enhanced analytical performance. The smooth polystyrene surface and square design provide practical advantages for precise gravimetric work in controlled laboratory environments.
Practical Tips
Store weigh boats in a low-humidity environment to prevent moisture absorption that could affect tare weight.
Why: Polystyrene can absorb atmospheric moisture, leading to measurement drift in sensitive applications.
Use powder funnels or microspatulas to transfer samples rather than pouring directly from containers.
Why: Controlled transfer prevents spillage and ensures accurate sample placement within the weigh boat.
Avoid contact with strong acids, bases, or aromatic solvents that may degrade polystyrene.
Why: Chemical compatibility ensures measurement accuracy and prevents contamination of analytical samples.
Replace immediately if cracks or deformation are observed, even if minor.
Why: Structural integrity affects weighing accuracy and sample containment during transfer procedures.
Allow thermal equilibration between boats and laboratory environment before critical measurements.
Why: Temperature differences can cause buoyancy effects that influence analytical balance readings.
If static issues persist, increase laboratory humidity to 45-55% or use ionizing equipment.
Why: Controlled humidity and charge neutralization enhance the effectiveness of anti-static treatment.

Compliance
What is the maximum sample weight these weigh boats can accommodate?
Consult product datasheet for weight capacity specifications. The 46x46mm surface area is suitable for most analytical sample sizes, but capacity depends on sample density and analytical balance specifications.
Are these weigh boats compatible with organic solvents?
Polystyrene is compatible with most aqueous solutions and many organic solvents, but may be affected by aromatic hydrocarbons and chlorinated solvents. Test compatibility with specific solvents before critical applications.
How do I minimize static electricity issues during weighing?
These boats feature anti-static treatment, but additional measures include using an ionizing air gun, maintaining appropriate humidity (45-55% RH), and grounding the balance and operator.
Can these be used in cleanroom environments?
The boats can be used in controlled environments, but packaging and handling should follow cleanroom protocols. Consider pre-cleaning with appropriate solvents if required by facility procedures.
What is the temperature stability range?
Polystyrene maintains dimensional stability under standard laboratory conditions. Consult datasheet for specific temperature limits, particularly for applications involving heated samples.
How do these compare to aluminum weigh boats?
Polystyrene boats are lighter, disposable, and eliminate contamination concerns but have lower temperature resistance than aluminum alternatives. Choose based on sample requirements and reusability needs.
