OHAUS PX225D Pioneer PX5 Semi-Micro Balance, 82g/220g Capacity, 0.01mg/0.1mg Readability, AutoCal

OHAUS PX225D Pioneer PX5 Semi-Micro Balance — Dual-Range 0.01 mg Accuracy with AutoCal

Sub-0.1 mg weighing demands a balance that minimizes every source of uncertainty. The OHAUS PX225D Pioneer PX5 Semi-Micro Balance addresses this with dual-range capability — 0.01 mg readability up to 82 g and 0.1 mg readability up to 220 g — combined with fully automatic internal calibration and a glass draftshield, all within the accessible Pioneer PX form factor.

Key Features

• 0.01 mg Readability in Semi-Micro Range: Ten-microgram resolution supports trace-level analytical work, elemental analysis sample preparation, and high-sensitivity formulation tasks.
• Dual-Range Operation (82 g / 220 g): Automatically applies the appropriate resolution — 0.01 mg below 82 g, 0.1 mg up to 220 g — without manual range switching.
• AutoCal Fully Automatic Internal Calibration: Calibration triggers automatically in response to temperature changes, ensuring accuracy is maintained without operator intervention throughout the measurement session.
• Glass Draftshield with 80 mm Pan: At 0.01 mg resolution, protecting the pan from the smallest air movements is non-negotiable; the enclosed glass draftshield fulfills this requirement.
• Typical Repeatability of 0.02 mg: Excellent precision at the semi-micro range confirms the instrument's suitability for demanding trace-level measurement applications.
• USB and RS232 Connectivity: Both ports support GLP-formatted output with real-time clock timestamps for traceable documentation of semi-micro measurements.
• 10-Second Stabilization Time: The balance settles longer than precision counterparts, reflecting the additional sensitivity and the time required to resolve measurements at the 0.01 mg level.

Detailed Overview

The PX225D occupies a specialist position within the Pioneer PX range, serving applications where standard analytical precision is insufficient. Its AutoCal system is particularly valuable in semi-micro work because even minor thermal gradients can shift readings at 0.01 mg resolution — the automatic response removes the risk of measurement drift between manual calibration events. Linearity is rated within ±0.0001 g at the semi-micro range, verifying the instrument's suitability for traceable high-precision protocols. The dual-line LCD with dot-matrix secondary display provides procedural guidance during multi-step analytical operations. GLP/GMP outputs include user and project IDs, supporting documentation in pharmaceutical R&D and research institution audit trails.

Applications

• Trace elemental analysis and spectroscopy sample preparation requiring 0.01 mg accuracy
• Pharmaceutical R&D gravimetric measurements at the semi-micro level
• High-sensitivity density determination and pycnometry
• Academic research in analytical chemistry requiring sub-0.1 mg reproducibility
• Standards preparation and gravimetric calibration of volumetric glassware
