The W3200-500 is the Accuris Precision Balance with 500 g capacity and 0.001 g (1 mg) readability — the precision-balance tier in the Accuris weighing catalog. Distinct from the W3100 analytical-balance series (0.0001 g readability) by the 1 mg readability tier, which is sufficient for workflows where milligram precision (vs sub-milligram analytical precision) is the protocol requirement. The 500 g capacity supports mid-volume weighing workflows (buffer prep at 500 mL scale, reagent stock prep at multi-gram quantities, larger sample weighing) that exceed the analytical-balance 120 g / 210 g range.

Key Specifications
| SKU | W3200-500 |
| Voltage | 115 V (North American outlet) |
| Capacity | 500 grams |
| Readability | 0.001 g (1 mg) — precision-balance tier |
| Capacity sister (larger) | W3200-5K (5,000 g capacity, 0.01 g readability) |
Precision Balance vs Analytical Balance
The Accuris weighing catalog ships balances in two readability tiers:
| Family | Readability | Precision tier | When to pick |
| W3100 Analytical | 0.0001 g (0.1 mg) | Analytical (sub-milligram) | Reagent / sample weighing where 0.1 mg precision matters (analytical chemistry, pharmaceutical compounding, standard prep) |
| W3200 Precision (this kit's family) | 0.001 g (1 mg) | Precision (milligram) | Workflows where 1 mg precision is sufficient (buffer prep, reagent stock prep, sample weighing for non-analytical workflows) |
The W3200 precision-balance tier is roughly 30% lower acquisition cost than the W3100 analytical-balance tier at comparable capacity — the right pick when 1 mg precision is sufficient and the analytical-balance precision is overkill.
W3200 Precision Balance Family Position
| SKU | Capacity | Readability |
| W3200-500 (this product) | 500 g | 0.001 g (1 mg) |
| W3200-5K | 5,000 g | 0.01 g (10 mg) |
Pick W3200-500 for mid-volume precision-balance weighing (500 mL buffer prep, reagent stock prep, sample weighing in the gram range with 1 mg precision). For larger-capacity workflows where 10 mg precision is sufficient, the W3200-5K supports up to 5 kg.
Application Profile
Buffer prep at 500 mL scale — weighing buffer salts and reagents for 500 mL working-volume buffer batches.
Reagent stock prep — weighing reagents in the gram range for stock-solution prep.
Sample weighing for non-analytical workflows — clinical-research sample-prep workflows, biobank sample weighing, environmental sample mass-quantification.
Pharmacy and compounding workflows at mid-volume — pharmaceutical compounding where 1 mg precision is sufficient and the larger 500 g capacity supports the formulation total weight.
Educational and teaching labs — undergraduate biology, biochemistry, and chemistry teaching where 1 mg precision and 500 g capacity match the curriculum's weighing exercises.
Multi-purpose lab balances — general lab weighing where the milligram precision and larger capacity match most workflow requirements.
Frequently Asked Questions
What are the capacity and readability of the W3200-500? 500 g capacity with 0.001 g (1 mg) readability — the precision-balance tier.
How does a precision balance differ from an analytical balance? A precision balance reads to 1 mg (0.001 g); the analytical W3100 series reads to 0.1 mg (0.0001 g). The W3200 precision tier costs roughly 30 % less at comparable capacity and is the right pick when 1 mg precision is sufficient.
What is the larger-capacity sister? The W3200-5K — 5,000 g capacity with 0.01 g (10 mg) readability.
Are calibration weights included? No. External calibration requires NIST-traceable weights at the appropriate class (typically Class F1 or M1), supplied by the lab.
Can the W3200-500 run on 230 V? Yes, a 230 V variant is available by special order.
Ordering & Configuration
Calibration weight procurement. External calibration requires NIST-traceable calibration weights at the appropriate weight class (typically Class F1 or Class M1 for precision balances). Operator-supplied; not included with the balance.
Power configuration. 115 V (this SKU) for North American outlets; a 230 V variant is available by special order.
Confirm at quote: voltage configuration (115 V standard; 230 V variant by special order for international outlets), capacity (500 g vs the W3200-5K at 5,000 g), readability tier confirmation (1 mg precision vs analytical-balance 0.1 mg precision), calibration-weight inventory, training requirements, and lead time.

Accuris weighing catalog tiers:
- W3200-500 (this product, 500 g × 1 mg) — Precision balance, mid-volume
- W3200-5K (5,000 g × 10 mg) — Precision balance, larger capacity
- W3100 / W3100A series (120 g / 210 g × 0.1 mg) — Analytical balance, sub-milligram precision
Pick the W3200-500 when 1 mg precision is sufficient and the 500 g capacity matches the workflow. Pick the W3100 series when sub-milligram analytical precision matters.
