OHAUS EX224N/AD Explorer Analytical Balance, 220g Capacity, 0.1mg Readability, AutoCal, NTEP Certified

OHAUS EX224N/AD Analytical Balance — 220g at 0.1mg with Motorized Auto Doors

Where analytical accuracy at the sub-milligram level is non-negotiable, the OHAUS EX224N/AD Analytical Balance sets a dependable standard. With a 220 g capacity, 0.1 mg (0.0001 g) readability, motorized auto doors for contamination-free sample handling, and AutoCal internal calibration, it addresses the core demands of pharmaceutical research, material characterization, and certified quality operations.

Key Features

• Motorized Auto Doors: Electrically operated draftshield doors open and close at the touch of a sensor, preventing thermal and vibration disturbances from manual door handling—critical at the 0.1 mg resolution level.
• AutoCal Internal Calibration: Built-in motorized calibration weight self-activates when ambient temperature drift is detected, maintaining linearity of ±0.0002 g and eliminating the need for external calibration weights in routine use.
• 0.1mg Readability, 2-Second Stabilization: Class I accuracy with typical repeatability of 0.0001 g supports the exacting measurement needs of analytical chemistry, formulation research, and reference-standard verification.
• NTEP & Measurement Canada Certified: Legal-for-trade approval at 1 mg certified readability satisfies regulatory requirements for pharmaceutical and certified commercial weighing.
• 5.7-Inch Full-Color VGA Touchscreen: A large, high-resolution interface displays results, application status, and menu navigation clearly, reducing user errors during complex analytical workflows.
• 90 mm Stainless Steel Pan with Draftshield: The enclosed weighing environment and compact 90 mm pan are engineered for the small, precise samples typical of analytical chemistry and reference-weight comparison.
• USB, RS232 & Optional Ethernet: Data flows directly to LIMS, GLP-compliant printers, or spreadsheet systems; Ethernet extends connectivity to networked lab environments.

Detailed Overview

The OHAUS EX224N/AD Analytical Balance is purpose-built for analytical workflows where even the small vibration introduced by opening a draftshield door can distort a reading. Its motorized auto doors eliminate that variable, while AutoCal continuously monitors temperature and recalibrates the internal standard before drift can accumulate. The result is reliable 0.0001 g repeatability across extended measurement sessions—useful during density determination, pipette calibration, formulation checking, and SQC sampling. A 2-second stabilization time balances analytical care with practical throughput. With support for 19 weighing units, the balance serves gemological, pharmaceutical, and research applications from a single certified platform. The 15.5 × 13.8 × 9.1 in housing accommodates standard lab bench depths, and the stainless steel pan withstands routine chemical cleaning.

Applications

• Pharmaceutical API weighing and reference-standard calibration
• Pipette calibration and gravimetric verification in analytical labs
• Density determination for polymer, mineral, and pharmaceutical samples
• Certified precious-metal and gemological mass determination
• Quality-control SQC sampling requiring Class I accuracy
