OHAUS PX323/E Pioneer PX Precision Balance, 320g Capacity, 0.001g Readability, GLP/GMP

OHAUS PX323/E Pioneer PX Precision Balance — 320g Capacity at 1 mg for Research and QC Labs

Where the 160 g PX163/E runs short on capacity, the OHAUS PX323/E Pioneer PX Precision Balance takes over — delivering exactly 320 g of range at the same 0.001 g resolution. This external-calibration model is designed for laboratories that need more headroom for sample vessels and containers without sacrificing the milligram accuracy their workflows require.

Key Features

• 320 g Capacity at 0.001 g Readability: Double the range of the 160 g model, accommodating larger containers, heavier sample matrices, or multiple-component formulation steps without compromising 1 mg precision.
• Glass Draftshield for Stable 1 mg Results: The enclosed chamber isolates the weighing pan from laboratory airflow, which would otherwise introduce variability that exceeds the instrument's 1 mg resolution.
• External Calibration for Accredited Programs: Calibrated with user-supplied certified masses, the /E variant integrates into ISO 17025 or GMP calibration workflows where traceable external standards are required.
• Dual USB and RS232 Connectivity: Both interfaces ship included and ready for use, supporting connection to LIMS, thermal printers, or Windows-based weighing software.
• GLP/GMP Data Output with Timestamping: Each printout or data transmission carries date, time, and user-definable IDs, satisfying the traceability requirements of regulated quality systems.
• 2-Second Stabilization: Despite the larger capacity and milligram-level resolution, readings settle in two seconds — maintaining practical throughput for multi-sample laboratory routines.
• Broad Weighing Unit Suite: Nineteen units spanning grams, kilograms, milligrams, carats, Tael variants, and more accommodate a wide spectrum of laboratory and commercial applications.

Detailed Overview

The OHAUS PX323/E shares the core specifications that make its sibling PX163/E reliable: ±0.002 g linearity and 0.001 g typical repeatability. The meaningful difference is the 320 g upper limit, which opens the balance to heavier flasks, denser sample matrices, and formulation protocols that involve more total mass. The 120 mm stainless-steel pan is well-matched to standard laboratory glassware. Operating through the 10°C–30°C range, it performs reliably in controlled laboratory conditions. Security-lockout and software-reset provisions protect calibration parameters in shared-instrument settings, and the two-line backlit LCD keeps operational information accessible without a complex interface.

Applications

• Pharmaceutical compound dispensing at milligram resolution with larger vessel tare weights
• Chemical analysis and gravimetric method work requiring 1 mg precision over broader sample ranges
• Gemstone and precious-metal trade weighing for stones with higher carat masses
• Animal weighing of small laboratory specimens such as rodents
• Density determination of moderately sized material samples

Why Choose the OHAUS PX323/E?

The PX323/E is the right choice when 160 g falls short but 1 mg resolution remains non-negotiable. Its additional capacity preserves the precision that research and regulated QC laboratories depend on, without requiring a step up to a more complex platform.
