The W3200-120 is the smallest-capacity / highest-precision entry in the Accuris W3200 Precision Balance family — 120 g capacity × 0.001 g (1 mg) readability. The 1 mg readability tier is one tier below the W3100 / W3101A / W3102A analytical balances (0.1 mg readability) and appropriate for workflows where 1 mg precision is sufficient and the analytical-balance precision is over-engineered.

Two readability tiers in the family:
- 1 mg readability (120 g, 320 g, 500 g) — higher-precision workflows at lower-capacity range
- 10 mg readability (1200 g, 3200 g, 5000 g) — bulk weighing at higher-capacity range with relaxed precision
Pick the W3200-120 when: workflow needs 1 mg readability at compact capacity (small samples, primary-reagent micro-prep, sub-100 g weighing where the analytical-balance 0.1 mg readability is over-engineered).
Application Profile
Sub-100 g sample weighing at 1 mg precision — biochemistry sample weighing, primary-reagent preparation, peptide / protein bulk-prep where 1 mg precision is sufficient.
Multi-investigator shared bench with mixed precision needs — facilities running both analytical (0.1 mg) and precision (1 mg) workflows on shared bench benefit from W3200 procurement alongside W3100A series.
Educational laboratory precision-balance training — coursework introducing balance-readability hierarchy.
Cost-optimized lab procurement — labs where 1 mg readability is sufficient benefit from W3200 cost ($1,220) vs W3100A analytical balance ($2,219+).
Method-development workflows — protocol-development workflows where precision-balance tier matches method-validation precision requirements.
Frequently Asked Questions
What is the readability and capacity of the W3200-120? 120 g capacity × 0.001 g (1 mg) readability — the smallest-capacity, highest-precision entry in the W3200 precision balance family.
How does a 1 mg precision balance differ from an analytical balance? The W3200-120's 1 mg readability is one tier below the W3100/W3101A/W3102A analytical balances (0.1 mg) — appropriate where 1 mg precision is sufficient and analytical precision would be over-engineered.
Which calibration weights does the W3200-120 need? The W1100-200 F1 set ($618) for full-range calibration, or the W1005 family M1 weights for cost-optimized calibration.
When should I choose the W3200-120 over a higher-capacity W3200? When the workflow needs 1 mg readability at compact capacity (small samples, sub-100 g weighing); step to the W3200-320/500 for larger 1 mg-tier samples.
Ordering & Configuration
