OHAUS EX324N Explorer Analytical Balance, 320g Capacity, 0.1mg Readability, AutoCal, NTEP Certified, Touchscreen

OHAUS EX324N Analytical Balance — 320g Extended Range at 0.1mg Resolution

A wider analytical capacity without sacrificing sub-milligram precision—that is the practical advantage offered by the OHAUS EX324N Analytical Balance. Running to 320 g at 0.0001 g readability, with AutoCal internal calibration and NTEP Class I certification, it handles the larger sample sizes common in pharmaceutical development and environmental analysis while maintaining the resolution demanded by rigorous analytical methods.

Key Features

• 320g Analytical Capacity: A 100 g extended range over comparable 220 g models accommodates larger containers, multi-sample setups, and samples requiring displacement-based density calculations without overloading the pan.
• AutoCal Internal Calibration: Thermal drift triggers automatic internal recalibration, sustaining ±0.0002 g linearity throughout extended measurement sessions without any manual weight handling.
• 3-Second Stabilization Time: Deliberate settling at the analytical resolution level ensures results are fully stable before recording, reducing the risk of capturing an intermediate reading during quiet-critical analyses.
• NTEP Class I Certification: Legal-for-trade approval at 1 mg certified readability supports regulatory compliance in pharmaceutical production, certified reference weighing, and commercial analytical services.
• Included Glass Draftshield: The fully enclosed weighing chamber maintains stable air conditions around the 90 mm stainless steel pan, directly supporting the 0.0001 g repeatability specification in real laboratory environments.
• 5.7-Inch Full-Color VGA Touchscreen: Clear application selection and real-time status monitoring on a bright, adjustable display keep complex analytical workflows moving efficiently.
• 19-Unit Measurement Library: Covers milligrams, carats, grains, troy ounces, and 15 additional units for versatile application across pharmaceutical, gemological, and academic labs.

Detailed Overview

The OHAUS EX324N Analytical Balance is built for analysts who need a certified 0.1 mg instrument with enough capacity to handle the containers and sample masses associated with pharmaceutical development, environmental sampling, and material-characterization work. The 320 g range keeps the balance compatible with standard 100 mL volumetric flasks and typical sample containers, reducing the need to transfer samples into lighter vessels. AutoCal brings automatic recalibration to the analytical level, so the balance remains accurate after temperature changes from HVAC cycling or door openings. The 90 mm pan diameter matches most analytical glassware footprints, and the included in-use cover protects the pan and draftshield between sessions. With 15-plus built-in application modes—including SQC, differential weighing, and pipette adjustment—the EX324N handles the full analytical task spectrum from a single instrument.

Applications

• Pharmaceutical API and excipient weighing requiring extended capacity
• Environmental sample mass determination for gravimetric analysis
• Density determination of polymers, minerals, and solid pharmaceutical forms
• Pipette calibration and gravimetric verification in analytical chemistry
• Certified gemological and precious-material weighing in carat units
