The W3200-5K is the largest-capacity precision balance in the Accuris W3200 family — 5,000 g (5 kg) capacity with 0.01 g (10 mg) readability. Sized for bulk reagent prep workflows (multi-kilogram buffer batch prep, bulk media prep, large-volume reagent stock prep), larger sample weighing (multi-kilogram environmental samples, food-science samples, bulk biological-material weighing), and any workflow where the smaller W3200-500 (500 g capacity) doesn't support the workflow's total weight.
The readability trade-off: at 10 mg readability vs the W3200-500's 1 mg, the larger-capacity W3200-5K is one tier coarser. This is appropriate for bulk-weight workflows where 10 mg precision on a 5 kg sample (0.0002% precision) is sufficient — but 10 mg precision is too coarse for milligram-range workflows that the W3200-500 covers.

W3200 Family Position
| SKU | Capacity | Readability | When to pick |
| W3200-500 | 500 g | 0.001 g (1 mg) | Mid-volume weighing where 1 mg precision matters |
| W3200-5K (this product) | 5,000 g (5 kg) | 0.01 g (10 mg) | Bulk weighing where 10 mg precision is sufficient AND larger capacity is required |
For sub-milligram analytical precision at smaller capacity, see the W3100 / W3100A analytical balance family.
Why a 5 kg Capacity Balance
Most lab balances cap at 200-500 g capacity — sized for typical reagent / sample weighing. The W3200-5K's 5 kg capacity covers workflows that exceed standard balance capacity:
- Bulk buffer prep at multi-litre scale — buffer batches at 5+ litres total volume where the buffer salt + container exceeds 500 g
- Bulk media prep for cell-culture core facilities — institutional cell-culture media prep at multi-kilogram total weight
- Environmental sample weighing — soil, water, sediment samples at sample weights up to 5 kg
- Food-science sample weighing — food-product weighing for nutritional analysis or QC workflows
- Bulk pharmaceutical compounding — institutional compounding pharmacy prep at larger formulation weights
- Bulk reagent stock prep — institutional reagent inventory prep at multi-kilogram bulk weight
Application Profile
Bulk buffer and media prep at institutional scale — institutional clinical-research, biotech, and pharma R&D labs prep buffers and media at multi-litre / multi-kilogram batch sizes.
Cell-culture core facility media prep — institutional cell-culture cores prep media at bulk scale for multiple researchers' workflows.
Environmental and food-science sample weighing — sample weighing at multi-kilogram scale where standard analytical balances don't support the sample weight.
Industrial pharma compounding — institutional compounding workflows at larger formulation weights.
Educational and teaching labs running bulk-prep exercises — teaching workflows where students learn bulk-prep methodology benefit from the larger capacity.
Frequently Asked Questions
Q: What capacity and readability does the W3200-5K have? A: 5,000 g (5 kg) capacity with 0.01 g (10 mg) readability.
Q: How does it differ from the W3200-500? A: The W3200-500 offers finer 1 mg readability at 500 g capacity; the W3200-5K trades to 10 mg readability for 10× the capacity (5 kg).
Q: Is 10 mg readability precise enough? A: On a 5 kg sample, 10 mg is 0.0002% precision — sufficient for bulk-weight workflows, but too coarse for milligram-range work (use the W3200-500 or an analytical balance).
Q: What calibration weights does it need? A: NIST-traceable weights at the appropriate class for 5 kg-range balances, typically Class M1 (operator-supplied).
Q: Can it run on 230V? A: Yes — 115V for North American outlets, with a 230V variant available by special order.
Ordering & Configuration
Calibration weight procurement. External calibration requires NIST-traceable calibration weights at the appropriate weight class for 5 kg-range balances (typically Class M1). Operator-supplied; confirm calibration-weight inventory at order — 5 kg balances may require larger calibration weights than analytical-balance workflows.
Power configuration. 115 V (this SKU) for North American outlets; a 230 V variant is available by special order.
Confirm at quote: voltage configuration, capacity needs (5 kg vs the W3200-500 at 500 g), readability tier confirmation (10 mg precision sufficient), calibration-weight inventory (Class M1 weights for 5 kg-range balance), training requirements, and lead time.
Warranty: Per Accuris standard warranty terms — confirm at quote.
Accuris W3200 precision balance family:
- W3200-500 — 500 g, 1 mg readability (mid-volume precision)
- W3200-5K (this product, 115 V) — 230 V available by special order — 5,000 g, 10 mg readability (largest-capacity precision)
Pick the W3200-5K when bulk weighing capacity matters and 10 mg precision is sufficient.
