Heathrow Scientific hexagonal antistatic weigh boats in flexible polystyrene for powder weighing, sample dispensing, and liquid transfer. The hexagonal shape creates three natural pour vertices for controlled directional transfer to any vessel without locating a corner. Available in four sizes: Small (~6 mL), Medium (~46 mL), Large, and X-Large. Antistatic treatment embedded during manufacturing. FDA food-grade. -10 to +70°C. Pack of 500.
Hexagonal vs. Square Weigh Boats: Which to Use?
| Feature | Hexagonal (this listing) | Square Weigh Boats |
|---|---|---|
| Pour Points | 3 vertices — pour from any point, no locating required | 4 corners — must orient boat to corner before pouring |
| Side Geometry | Sloping sides direct residue to pour vertex | Straight walls; manual corner-flexing required |
| Antistatic | All sizes — embedded permanent treatment | Available Standard or Antistatic |
| Colors | White | White, Blue, Black |
| Sterile Option | Small + Medium (120881, 120882) | Small + Medium (120880, 120710) |

Features and Benefits
Three pour points at every other vertex — unlike square weighing boats that require corner-locating, hexagonal weigh boats present a pour point in three orientations. Reduces spills during transfer to volumetric flasks, reaction vessels, and chromatography funnels.
Sloping sides improve transfer yield — tapered walls direct residual sample toward the pour vertex for more complete transfer than flat-walled square boats.
Antistatic polystyrene — permanent embedded treatment — eliminates static adhesion of fine metal powders, API particles, and electrostatically sensitive materials to boat surfaces.
Flat base for balance stability — sits flat on analytical balance pans. Compatible with standard and semi-micro analytical balances.
FDA food-grade PS — biologically inert — resistant to dilute acids, dilute bases, aqueous solutions, and alcohols. Compatible with moisture analyzers to +70°C.
Frequently Asked Questions
Are sterile hexagonal weigh boats available?
Yes. See Heathrow Scientific Sterile Hexagonal Weigh Boats (120881 Small, 120882 Medium), available in 5-wrap sterile packaging, 500/pk.
When should I use hexagonal instead of square weigh boats?
Hexagonal weighing boats are preferred when transferring samples to narrow-neck vessels (volumetric flasks, HPLC vials, chromatography columns) where directional pour control reduces spills. Square weigh boats are more versatile for general taring, mixing, and moisture analysis.
