Square Antistatic Polystyrene Weighing Boats — White, 10/100/250 mL, 500/Case
These Globe Scientific square antistatic weighing boats are molded from rigid white polystyrene with a flat square bottom for stable placement on analytical balances. Designed for sample weighing, powder transfer, and reagent prep, the antistatic surface minimizes static cling so fine powders release cleanly and readings settle quickly.

Frequently Asked Questions
Are these weighing boats truly antistatic?
Yes. The polystyrene is formulated with an antistatic treatment that reduces surface charge, helping fine powders release cleanly and allowing balance readings to stabilize faster than with untreated dishes.
Can these boats be used with organic solvents?
Polystyrene tolerates aqueous buffers and dilute acids or bases well, but it is not recommended for acetonitrile, aromatic, or chlorinated solvents, which can craze or dissolve the material. Limit alcohol exposure to brief contact.
How many boats come in each pack?
Each SKU ships 500 boats per case. Three volumes are offered: 10 mL, 100 mL, and 250 mL, letting you match dish size to sample mass and reduce reagent waste.
Are these weighing boats sterile?
No, they are supplied non-sterile for general gravimetric and sample-handling use. For applications requiring sterility, validate an appropriate decontamination method or select a sterile alternative.
