OHAUS AX225D Adventurer Semi-Micro Balance, 102g/220g Capacity, 0.01mg/0.1mg Readability, AutoCal

OHAUS AX225D Adventurer Semi-Micro Balance — Dual-Range 0.01 mg / 0.1 mg with AutoCal

Two weighing modes, one instrument — the OHAUS AX225D Adventurer Semi-Micro Balance provides a 102 g range at 0.01 mg (five-decimal) resolution and a 220 g range at 0.1 mg (four-decimal) resolution in a single platform. AutoCal automatic internal calibration keeps the balance continuously verified against temperature drift, freeing researchers to focus entirely on their samples rather than calibration status.

Key Features

• Dual-Range Semi-Micro Operation: Switching between the 102 g / 0.01 mg mode and the 220 g / 0.1 mg mode allows a single instrument to handle both ultra-precise small-sample weighing and more practical mid-range work, eliminating the need for two separate balances.
• AutoCal Fully Automatic Internal Calibration: Temperature-sensing circuitry triggers internal calibration automatically whenever drift is detected, maintaining accuracy across laboratory temperature fluctuations without operator intervention.
• Full-Color 4.3-Inch WQVGA Touchscreen: High-resolution touch navigation makes application switching seamless and reduces the chance of mode-selection errors that could compromise five-decimal measurements.
• Glass Draftshield for Stable Semi-Micro Readings: An enclosed weighing chamber is essential at 0.01 mg — even minimal air currents introduce errors that would exceed the resolution specification without protection.
• 8-Second Stabilization, 20 mg USP Minimum Weight: The stabilization time reflects the extreme sensitivity of the 0.01 mg mode; the 20 mg USP minimum weight confirms suitability for validated pharmaceutical applications at this resolution tier.
• USB Host, USB Device, and RS232 Connectivity: All three ports ship included, supporting simultaneous data logging to a USB drive, LIMS integration via USB device, and RS232 peripheral connection.
• Three-Level GLP/GMP User Management: Role-based access ensures calibration parameters and operational settings are protected, with user and project IDs embedded automatically in compliance records.

Detailed Overview

The OHAUS AX225D occupies a specialized niche where analytical resolution is insufficient but a dedicated microbalance is cost-prohibitive. In semi-micro mode, linearity is ±0.1 mg with 0.00002 g typical repeatability at the 102 g range. AutoCal handles the temperature sensitivity inherent to this resolution level, making the AX225D practical for real-world lab conditions rather than only temperature-stable clean-room environments. The 80 mm stainless-steel pan accommodates standard micro-vessels. The 8-second stabilization time reflects the precision demanded in the 0.01 mg mode, while the 0.1 mg mode offers 3-second-class settling for faster throughput in less demanding tasks.

Applications

• Reference standard preparation and purity determination at 0.01 mg accuracy
• Pharmaceutical microformulation and low-dose API dispensing
• Thin-film and nanomaterial mass characterization in materials research
• Dual-mode laboratories requiring both semi-micro and analytical precision from one bench position
• High-sensitivity solution preparation for trace chemical analysis

Why Choose the OHAUS AX225D?

The AX225D eliminates the compromise between resolution and range by providing both in a single instrument. AutoCal removes the calibration burden at the most demanding measurement levels, and the touchscreen interface makes it accessible to analysts who are not semi-micro balance specialists.
