OHAUS EXR125 Explorer EXR Semi-Micro Balance, 120 g Capacity, 0.01 mg Readability, AutoCal, Touchscreen

OHAUS EXR125 Semi-Micro Balance — 0.01 mg Resolution for Demanding Micro-Weighing Tasks

Where analytical balances reach their limits, the OHAUS EXR125 Semi-Micro Balance takes over. Resolving mass to 0.01 mg (10 µg) across a 120 g range, this instrument is designed for sample preparation workflows where every microgram counts. Combined with AutoCal™ automatic calibration and an anti-static enclosed draftshield, it provides the measurement stability that pharmaceutical synthesis, micro-formulation, and reference material work require.

Key Features

• 0.01 mg (10 µg) Readability: Five-decimal resolution supports high-precision micro-weighing tasks that fall beyond the reach of standard analytical balances.
• AutoCal™ Automatic Internal Calibration: Temperature-triggered recalibration ensures the balance stays within specification throughout extended shifts without user action.
• Anti-Static Glass Draftshield: Fully enclosed 80 × 80 mm pan chamber eliminates electrostatic artifacts and airflow disturbances that compromise readings at the microgram level.
• 7-inch TFT Touchscreen with Touchless Sensors: Glass-overlay display lets analysts control taring and application switching hands-free, minimizing vibration during delicate weighing sequences.
• Multi-Interface Connectivity: USB Device, two USB Host ports, RS232, and Ethernet facilitate seamless data transfer; optional Wi-Fi/Bluetooth supports wireless LIMS connectivity.
• 1,000-Entry Sample Library: Preloaded reference weights accelerate repetitive micro-formulation and parts-counting workflows without re-entry.
• Structured User Access Control: Four permission levels and a 100,000-record audit log meet GLP documentation requirements for regulated environments.

Detailed Overview

The EXR125 is the instrument of choice when measurement uncertainty at the microgram level directly affects research outcomes or product quality. Its 80 × 80 mm stainless-steel pan suits micro-scale containers and weighing boats used in trace-level chemistry. Operating between 10°C and 30°C, the balance maintains specification under typical laboratory HVAC conditions. The Explorer EXR platform's HID compatibility removes the burden of driver installation, making integration with any data-acquisition system straightforward. NTP time synchronization delivers accurate timestamps for every logged result, a prerequisite in GXP-governed research. With 11 built-in weighing applications — including density determination, differential weighing, and dynamic weighing — the EXR125 handles diverse micro-laboratory protocols from a single terminal.

Applications

• Micro-formulation of pharmaceutical compounds requiring microgram-level accuracy
• Trace analysis and reference standard preparation in analytical chemistry
• Biological sample preparation for assay development and validation studies
• Materials research involving nano- and micro-scale sample characterization
• Environmental analysis where very small sample masses are typical
