Aluminum Weighing Dishes, 30mm Diameter, 0.3g (8mL Capacity), Crimped Side with Tab — 1000/Case
The Globe Scientific Aluminum Dish, 30mm is a lightweight disposable weighing pan engineered for gravimetric sample prep, moisture determination, and ashing applications. Crimped sidewalls add rigidity for easy handling, while the integrated tab speeds transfer onto and off the balance. Each dish holds approximately 8mL, making it well suited for small-volume liquid evaporation and solids weighing.

Frequently Asked Questions
What is the capacity and dish weight of SKU 8309?
Each 30mm dish weighs roughly 0.3g and holds about 8mL, ideal for small solid samples and low-volume liquid evaporation at the balance.
Are these aluminum dishes suitable for ashing in a muffle furnace?
Yes. Aluminum dishes tolerate moderate-temperature drying and are commonly used for loss-on-drying and ashing prep. Verify your furnace setpoint stays below aluminum's melting point (about 660°C).
How are the dishes packaged and sold?
SKU 8309 is sold by the case of 1000 dishes at $93.60 per case. Pricing is per pack as the manufacturer supplies it.
Will dilute acids or bases react with the aluminum?
Aluminum resists many organic solvents and alcohols well but is corroded by many acids and most caustics. Avoid prolonged contact with acidic or alkaline samples; keep dishes dry between uses.
