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
