These weigh boats are disposable and are a safe, yet inexpensive line of containers for weighing powdered or liquid samples. Constructed of resilient anti-static polystyrene plastic, which ensures unusually accurate control of “pour-outs” after weighing, whether performed by hand or with forceps clamped to the lip rim. Have multiple uses. Can be used as discard trays for broken ampules and other small problem items, or for quick freezing of samples. They are rugged enough for mixing, non-sticking and very convenient! The blue dish contrasts with white powders and solids, increases sample visibility and improves measuring accuracy.
