Aluminum Weighing Dishes, Crimped Side with Tab, 50–76 mm, 100/Pack
The Globe Scientific Aluminum Dish is a lightweight, disposable pan engineered for fast sample weighing, moisture-content determination, and solvent evaporation. Crimped sidewalls and an integrated tab give rigidity and easy handling, while smooth aluminum surfaces release residue cleanly. Bench chemists rely on these dishes for gravimetric prep, oven drying, and routine ashing where single-use convenience prevents cross-contamination.

Frequently Asked Questions
What maximum temperature can these aluminum dishes withstand?
Aluminum tolerates typical drying and ashing temperatures well above 500 °C, making these dishes suitable for oven drying, moisture analysis, and loss-on-ignition work. Confirm your method's setpoint against aluminum's melting point near 660 °C.
Are the dishes graduated or marked with volume?
No. The stated 20, 40, and 80 mL figures are nominal capacities for the 50, 60, and 76 mm formats; the dishes have no printed graduations and are intended for gravimetric, not volumetric, use.
How are the dishes packaged and sold?
Each is sold per pack of 100 dishes, with 10 packs per carton (1,000 dishes). Prices shown are per pack; full-carton and multi-carton tiered pricing is available on request.
Which reagents should I avoid in these dishes?
Avoid strong or oxidizing acids and caustic bases, which corrode aluminum. The dishes handle alcohols, acetonitrile, aromatic and chlorinated solvents, and neutral aqueous buffers well for routine weighing and evaporation.
