Set-vs-set selection:
- W1105-8-50 (this product): Smallest, lowest-cost, low-mass-only (1-50g), basic standard balance calibration
- W1105-12-500 / -13-1000. Larger sets, no sub-mg coverage but extended mid/high mass range
- W1105-21-100 / -22-200, Sub-milligram coverage included, analytical balance calibration
Set vs Individual Weight Procurement
| Procurement | Cost | Pieces | Best for |
| W1105-8-50 set (this product) | $149 | 8 pieces, 1-50g M1 | Single-procurement low-mass calibration |
| Individual W1005 weights (1g + 2g + 5g + 10g + 20g + 50g) | $149.00 ($17 + $16 + $21 + $21 + $28 + $30 + duplicates) | 6+ pieces | Per-mass procurement; replacement-only orders |
The set carries a small premium over individual weights (~$30 vs piece-by-piece), justified by case + organized handling + multi-piece convenience.
Application Profile
Low-mass standard balance calibration. 50 g – 200 g standard balances where calibration coverage is needed in the low-mass range only.
Educational laboratory calibration training. Undergraduate analytical chemistry programs introducing calibration concepts.
Method-development workflows. Protocol-development workflows where low-mass calibration accuracy is being verified.
Multi-balance facility low-cost procurement. Facilities with multiple low-capacity balances benefit from M1 set per balance.
Replacement / upgrade procurement. Labs upgrading from older calibration sets.
Ordering & Configuration
Pair with W1000-TF tweezers.
Confirm case / storage. Calibration weight sets ship in protective case with weight-position cutouts.
Confirm at quote: balance grade and capacity, low-mass-range coverage need, case inclusion, and lead time.
