Aluminum Weighing Dishes, Crimped Side & Curled Lip, 20–200 mL, 100/Pack
The Globe Scientific Aluminum Weigh Dish is a disposable, smooth-wall pan engineered for fast gravimetric weighing, moisture determination, and sample ashing. Crimped sidewalls add rigidity for handling, while the curled lip gives a clean pour edge and reinforced rim. Available in four volumes from 20 mL to 200 mL to match microbalance samples through bulk drying applications.

Applications
- Gravimetric sample weighing on analytical and top-loading balances
- Moisture and loss-on-drying analysis in ovens up to aluminum's working temperature
- Ashing of organic samples prior to mineral analysis
- Solvent evaporation and residue determination
- Aliquoting powders, granules, and pastes for QC labs
- Sample staging in food, environmental, and agricultural testing
Chemical Resistance
| Reagent Class | Compatibility |
| Aqueous buffers (neutral pH) | Good |
| Dilute acids | Limited — aluminum is attacked by acids; avoid prolonged contact |
| Dilute bases | Poor — aluminum reacts with alkaline solutions |
| Alcohols | Good |
| Acetonitrile | Good |
| Aromatic solvents | Good |
| Chlorinated solvents | Good |

Frequently Asked Questions
What is the pack size for these aluminum weigh dishes?
Each SKU ships as a pack of 100 dishes. Listed prices are per pack; tiered pricing applies to larger institutional orders.
Can these dishes be used for moisture analysis and ashing?
Yes. The aluminum construction withstands typical drying-oven temperatures used for loss-on-drying and ashing, then can be discarded to avoid carryover between samples.
Are aluminum weigh dishes compatible with acids or bases?
Aluminum resists most organic solvents and neutral aqueous solutions but reacts with acids and bases. For strongly acidic or alkaline samples, use a polypropylene or PTFE alternative.
What is the difference between the 70 mL and 75 mL dishes?
Both share a 70 mm outer diameter; SKU 8313 (75 mL) and SKU 8314 (70 mL) differ slightly in depth and capacity to suit varying sample volumes within the same footprint.
