OHAUS AX125D Adventurer Semi-Micro Balance, 82g/120g Capacity, 0.01mg/0.1mg Readability, AutoCal

OHAUS AX125D Adventurer Semi-Micro Balance — Dual-Range 0.01mg/0.1mg Precision

Sub-milligram accuracy for trace-level analysis requires an instrument that minimizes every source of error. The OHAUS AX125D Adventurer Semi-Micro Balance delivers dual-range capability — 0.01mg readability at 82g and 0.1mg at 120g — paired with AutoCal automatic calibration and an enclosed draftshield, giving analytical chemists and pharmaceutical researchers the measurement confidence needed for reference standard preparation and micro-scale formulation.

Key Features

• 0.01mg High-Resolution Mode: At 82g capacity, the balance resolves to 10 micrograms — a level of sensitivity sufficient for trace analytical weighing, standard preparation, and micro-dosing verification.
• Dual-Range Operation: Automatic switching to 0.1mg readability at up to 120g extends practical capacity for sample vessels and larger analytical specimens without changing instruments.
• AutoCal Automatic Internal Calibration: Temperature-triggered recalibration keeps the balance within specification throughout extended measurement sessions, critical for analytical results that require stable reference conditions.
• Enclosed Draftshield: The full draftshield enclosure protects sub-milligram measurements from air currents that would otherwise cause instability, a non-negotiable feature at this resolution level.
• 4.3-Inch Color Touchscreen: WQVGA full-color display presents measurement values, application menus, and user settings with clarity, reducing misreading at sub-milligram resolution.
• 8-Second Stabilization Time: The extended settle time compared to heavier-duty balances reflects the fine-resolution measurement process; at 0.01mg, each digit represents 10 micrograms.
• 80mm Pan with Full Application Suite: The compact 80mm stainless steel pan is sized for analytical vessels and weighing boats, with density determination, formulation, and parts-counting modes built in.

Detailed Overview

The OHAUS AX125D Semi-Micro Balance serves the niche between a full micro balance and a standard analytical balance — providing resolution well beyond 0.1mg analytical performance while remaining accessible in price and footprint. At 0.00002g repeatability in high-resolution mode, it meets requirements for USP reference standard preparations, pharmaceutical active ingredient verification, and quantitative analytical chemistry. The linearity specification of ±0.1mg across the full high-resolution range confirms that measurement accuracy is maintained across the measurement span, not just at a single calibration point. The minimum detectable weight of 20mg (USP 0.1% method) gives analysts a practical lower boundary for reliable use in regulated analytical environments. AutoCal removes the risk of calibration drift accumulating between manual checks, particularly important in high-traffic analytical labs where ambient temperature fluctuates with occupancy and HVAC cycling.

Applications

• Reference standard and certified material preparation
• Pharmaceutical active ingredient micro-dosing and verification
• Quantitative analytical chemistry and method validation
• Trace-level environmental and food safety sample preparation
