OHAUS EXP324/AD Explorer EXP Analytical Balance, 320 g Capacity, 0.1 mg Readability, AutoCal, Touchscreen

OHAUS EXP324/AD Analytical Balance — 320 g Capacity Without Compromising 0.1 mg Accuracy

Pushing the boundaries of conventional analytical weighing ranges, the OHAUS EXP324/AD Analytical Balance supports a 320 g maximum load at 0.1 mg readability. For research and quality teams regularly working with heavier crystalline compounds, denser metal samples, or larger volumetric vessels, this extended range removes a common practical obstacle while retaining full analytical-grade precision and the compliance features the Explorer EXP line is known for.

Key Features

• 320 g Analytical Capacity: Accommodates samples nearly three times heavier than a typical 120 g analytical balance while maintaining 0.1 mg resolution throughout the range.
• AutoCal Internal Calibration: Thermal-change-triggered automatic calibration prevents drift across the full 320 g range, ensuring consistent 0.1 mg accuracy at any load.
• Ionizer and Anti-Static Glass Draftshield: Active static neutralization and an enclosed weighing chamber protect 0.1 mg measurements from the electrostatic and airflow interference that escalates at lower sample masses.
• Motorized Anti-Pinch Autodoors: Two touchless sensors trigger smooth electric door operation, enabling clean-room-compatible, hands-free sample handling.
• 2-Second Stabilization Time: Consistent fast settling across a wide load range supports high-volume analytical laboratories where time per measurement directly affects productivity.
• Extensive Application Modes: Fifteen built-in modes—including density determination, formulation, and fill-weight variation—cover the workflows typical of pharmaceutical and research labs.
• Audit-Ready Platform: Four-level user management, NTP time sync, and a 100,000-entry log address regulatory documentation requirements in GMP-governed facilities.

Detailed Overview

The OHAUS EXP324/AD Analytical Balance delivers the combination of extended range and high resolution demanded by modern multi-purpose analytical laboratories. The stainless steel SST 316 pan (90 × 90 mm) resists chemical exposure and remains easy to remove for cleaning between samples. A 100 mg USP minimum weight at the 0.1% threshold confirms reliable analytical performance across the full capacity span. The balance's modular design allows authorized service technicians to upgrade individual components, extending service life and protecting the instrument investment. Connectivity through Ethernet, USB-C, and dual USB-A ports enables real-time transfer to LIMS, ELN, or direct printing without secondary software. The optional ionizer anti-static kit and in-use cover further adapt the EXP324/AD to demanding environmental conditions.

Applications

• High-mass pharmaceutical compound weighing at analytical precision
• Metal alloy and dense material density determination
• Multi-component formulation with heavier vessel tare weights
• Reference standard preparation using larger calibration masses
• SQC and fill-weight variation monitoring in production environments

Why Choose the OHAUS EXP324/AD?

For analytical chemists who have worked around a 120 g or 220 g ceiling by using less precise instruments for heavier samples, the EXP324/AD removes that compromise entirely. Full 0.1 mg accuracy at 320 g, automatic calibration, and a complete compliance infrastructure make it a single-instrument solution for a wide analytical workload. Order today and eliminate the trade-off between capacity and precision.
