The W4000-100 is the Accuris Mini Balance — an extraordinarily compact, AAA-battery-powered portable balance with 100 g capacity × 0.01 g (10 mg) readability. Per the Accuris Mini Balance literature: footprint of only 2.6 × 3.9 inches (less than 3 in. wide), backlit LCD, calibration function, snap-on protective cover for transport. The Mini balance tier is the smallest physical-footprint balance in the Accuris catalog — designed for portable / field-deployment / individual-investigator workflows where a full bench-top compact balance (W3300 family) is over-engineered.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

The W4000 Mini tier vs W3300 Compact tier:
- Same readability classes (10 mg / 100 mg) at sub-kg / kg-scale capacities
- Mini delivers portability — AAA-battery operation, snap-on protective cover, 2.6 × 3.9 in footprint
- Compact delivers bench reliability — AC-powered, larger weighing pan, more advanced display features
- Mini cost ~6-10× lower than compact for similar readability — engineered for field / portable / educational use

| Best fit | Field / portable / educational / individual-investigator | Routine bench weighing, multi-investigator shared bench |
Pick the Mini (W4000-100) when:
- Portability matters — field-lab, satellite-lab, mobile teaching, individual-investigator portable kit
- Budget-tier procurement is the priority ($52 vs $354 for the compact equivalent)
- AAA-battery operation is required (no AC outlet available, or workflow requires bench-power independence)
- The W4000-100 is bundled into the E1101-SK myGel Mini Electrophoresis Starter Kit — labs ordering the Starter Kit get this balance included for agarose weighing at gel-pour time
Application Profile
Field-deployment workflows — environmental sampling, agricultural diagnostics, veterinary diagnostics labs benefit from the AAA-battery portable balance.
Individual-investigator portable kits — researchers needing their own dedicated balance for portable workflows.
Educational laboratory programs — undergraduate / graduate programs benefit from the compact balance for student-cohort exercises (multiple per teaching bench at low per-unit cost).
myGel Mini agarose weighing workflow — bundled into the E1101-SK Starter Kit for agarose weighing at gel-pour time (typical 0.5-2.0 g agarose for the 25 mL gel-tray volume).
Backup / spare balance — labs maintaining a portable spare balance for travel, field-deployment, or workstation backup.
Multi-cycler facility procurement — facilities running multiple workstations benefit from a Mini balance per workstation at low per-unit cost.
Replacement / upgrade procurement — labs replacing aging portable balances benefit from the Mini family compact form factor.

Ordering & Configuration
Battery inclusion. AAA batteries included with the chassis at first procurement — confirm at order. Plan for periodic battery replacement per workflow throughput (typical battery life depends on use intensity).
Calibration weights. The Mini balance's 10 mg readability supports calibration with standard M1 grade weights (W1005 family). For field-portable calibration, pair with W1005-100 (100 g M1 weight, $52.00) for full-range verification + W1000-TF tweezers ($42).
Confirm at quote: workflow portability needs (field vs bench), capacity (100 g vs 500 g sister W4000-500), starter-kit bundling (if also procuring myGel Mini), calibration weight pairing, and lead time.
Warranty: Per Accuris standard warranty terms — confirm at quote.
