The W3100-210 is the 210 g capacity variant of the Accuris Analytical Balance — same 0.0001 g (0.1 mg) analytical-balance precision tier as the W3100-120 (120 g sister), with the larger capacity supporting workflows where sample + container weight exceeds 120 g. Common scenario: weighing into pre-tared 50 mL conical tubes (empty conical ~12 g + sample), 250 mL bottles, or larger sample containers where the combined weight approaches or exceeds 120 g.

Key Specifications
| SKU | W3100-210 |
| Voltage | 115 V (North American outlet) |
| Capacity | 210 grams |
| Readability | 0.0001 g (0.1 mg) |

| List price | $2,576 |
Capacity Selection — 120 g vs 210 g
| Capacity | Use case |
| W3100-120 (120 g) | Standard reagent weighing where sample + container ≤ 120 g (typical reagent prep into small weigh boats or weighing paper) |
| W3100-210 (this product, 210 g) | Larger sample / container workflows — pre-tared 50 mL conical tubes with sample, larger weigh containers, multi-sample weighing in a single container |
For lower-capacity needs, the W3100-120 saves $357 vs this 210 g variant.
Compatibility & Configuration
For the full application profile, calibration-weight procurement guidance, and W3100 family context, see the W3100-120 parent page (which establishes the W3100 family reference content).
210 g-specific application profile:
Reagent weighing into 50 mL conical tubes — when buffer prep or reagent stock prep weighs reagent directly into pre-tared 50 mL conical tubes (eliminating the transfer step from weigh boat to container).
Multi-sample combined weighing — workflows that weigh multiple samples into a single tared container for combined-mass measurement.
Larger-volume reagent prep — bulk reagent prep where the container weight + bulk-volume reagent approaches or exceeds 120 g.
Combined sample + container weighing in clinical-research workflows — biobank intake or sample-prep workflows where the combined weight of pre-labeled containers + sample exceeds 120 g.
Frequently Asked Questions
Q: What are the capacity and readability of the W3100-210? A: 210 g capacity at 0.0001 g (0.1 mg) readability — the analytical-balance precision tier.
Q: Should I choose the 120 g or the 210 g model? A: Pick the 210 g W3100-210 when sample plus container weight exceeds 120 g (pre-tared 50 mL conical tubes, larger containers, multi-sample weighing); the 120 g W3100-120 saves $357 for smaller loads.
Q: Does the W3100-210 have internal calibration? A: No — it uses external calibration with operator-supplied weights. The internal auto-calibration variant is the W3100A-210.
Q: What calibration weights are required? A: NIST-traceable weights, typically Class F1 or Class E2 for analytical balances.
Ordering & Configuration
Calibration weight procurement. External calibration requires NIST-traceable calibration weights — typical Class F1 or Class E2 for analytical balances. Confirm calibration-weight inventory at order.
