Antistatic Square Weighing Boats, Polystyrene, Black — 10/100/250 mL, 500 per Case
The Globe Scientific Antistatic Square Weighing Boats deliver clean, accurate transfers for analytical weighing on electronic balances, sample prep for media and reagent formulation, and routine powder dispensing. Molded from polystyrene with a square-bottom geometry, each boat sits flat and pours without spilling. Static-dissipative treatment minimizes powder clinging and charge-induced balance drift.

Frequently Asked Questions
How does the antistatic treatment improve weighing accuracy?
The static-dissipative black surface bleeds off surface charge, so fine powders fall cleanly into the boat instead of clinging to the walls. This reduces transfer loss and prevents charge-induced balance drift during readings.
Are these weighing boats autoclavable?
No. Polystyrene is not autoclavable and deforms under heat. These boats are single-use, non-sterile consumables intended for room-temperature weighing tasks.
Which solvents should I avoid with these boats?
Avoid acetonitrile, aromatic solvents, and chlorinated solvents, which attack polystyrene. Aqueous buffers, dilute acids, and dilute bases are well tolerated; limit alcohol contact to brief exposures.
What is the pack size and how are they sold?
Each SKU is sold per case of 500 boats. Prices listed are per case: 10 mL (3619-10BK), 100 mL (3619-100BK), and 250 mL (3619-250BK).
