OHAUS EXR124 Explorer EXR Analytical Balance, 120 g Capacity, 0.1 mg Readability, AutoCal, Touchscreen

OHAUS EXR124 Analytical Balance — 0.1 mg Readability with AutoCal for 120 g Samples

Analytical weighing at the 0.1 mg level demands an instrument that eliminates every source of error, from airflow to temperature drift. The OHAUS EXR124 Analytical Balance addresses both: its enclosed anti-static glass draftshield protects the 90 × 90 mm pan, while AutoCal™ continuously monitors for calibration drift and corrects it without operator input. For chemists and pharmaceutical scientists who need both sub-milligram precision and reliable documentation, the EXR124 is a compelling choice.

Key Features

• 0.1 mg (0.0001 g) Readability: Four-decimal precision covers gravimetric analysis, API weighing, and reference standard preparation with confidence.
• Anti-Static Glass Draftshield: Fully enclosed weighing chamber neutralizes electrostatic charge on lightweight samples while shielding the pan from air currents.
• AutoCal™ Internal Calibration: Automated recalibration triggered by temperature change maintains accuracy throughout a full working day without manual weights or operator time.
• 7-inch Color Touchscreen: Intuitive glass-overlay interface with touchless sensors allows taring and application control without touching the terminal, reducing contamination risk.
• Multi-Port Connectivity: RS232, USB Device, dual USB Host, and Ethernet are built in; optional wireless module adds Wi-Fi and Bluetooth for LIMS integration.
• 11 Application Modes: From density determination using Archimedes' principle to differential weighing and formulation, all modes are accessible through the touchscreen menu.
• GLP-Ready Audit Log: A 100,000-entry internal log with four-tier user management supports regulated laboratory documentation requirements.

Detailed Overview

Designed for laboratories where sub-milligram accuracy is non-negotiable, the EXR124 delivers a 120 g maximum capacity paired with 0.1 mg resolution — a range suited to typical analytical sample sizes in pharmaceutical, chemical, and research settings. The compact 90 × 90 mm stainless-steel pan accommodates standard volumetric containers and weigh boats. Metal housing provides the rigidity needed to maintain calibration under repeated daily use, and the unit operates reliably across 10°C–30°C and up to 80% non-condensing relative humidity. The NTP time-synchronization feature stamps each result with a verifiable timestamp, a detail that matters in compliance-critical workflows. HID compatibility means connecting the balance to a PC requires no device driver installation.

Applications

• Active pharmaceutical ingredient (API) dispensing and gravimetric assay work
• Reference standard preparation and primary calibration in accredited labs
• Density determination of solids and highly viscous liquids
• Micro-formulation and compound preparation in research chemistry
• Educational laboratory training for quantitative analytical techniques
