OHAUS PX623/E Pioneer PX Precision Balance, 620 g Capacity, 0.001 g Readability, GLP/GMP

OHAUS PX623/E Pioneer PX Precision Balance — 620g Capacity at 1mg Resolution with Draftshield

Milligram-level precision in a precision balance format makes the OHAUS PX623/E Pioneer PX Precision Balance a versatile bridge between standard precision and full analytical work. With 0.001g readability across a 620g range — and an included glass draftshield to protect measurements from environmental interference — this balance handles fine chemical weighing, small-sample formulation, and density determination with analytical-class stability at a precision-class price.

Key Features

• 0.001g Readability Across 620g: Milligram discrimination on a balance suited to small-scale pharmaceutical, research, and specialty weighing tasks.
• Included Glass Draftshield: Shields the 120mm pan from ambient airflow, which is critical for stable readings at the 1mg level.
• 2-Second Stabilization Time: Balances speed and accuracy at high resolution — settling faster than many analytical balances while still achieving 1mg precision.
• GLP/GMP Output with Real-Time Clock: Structured, time-stamped print records support compliant documentation in regulated laboratory environments.
• Dual USB/RS232 Connectivity: Supports connection to both PCs and serial printers simultaneously for flexible data management.
• External Calibration with Span Point Selection: Multi-position verification using traceable external masses suits ISO/IEC 17025 and GLP calibration requirements.
• User-Definable IDs and Software Lockout: Enables structured multi-operator workflows and protects calibration settings from inadvertent changes.

Detailed Overview

The OHAUS PX623/E Pioneer PX Precision Balance occupies a specialized position: it provides 1mg readability in a precision balance chassis rather than a fully enclosed analytical design. The 120mm stainless steel pan is well-suited to small vessels and reaction flasks, while the included draftshield brings the environmental protection needed for reliable milligram measurement without requiring a separate analytical balance. Linearity of ±0.002g and repeatability of 0.001g confirm that performance meets expectations for small-scale research and pharmaceutical pre-formulation. The 2-second settling time — faster than many analytical models — makes it practical for settings where measurement throughput matters. With support for 19 units of measurement, including milligrams, carats, pennyweight, and troy ounces, the instrument serves diverse analytical disciplines.

Applications

• Pharmaceutical pre-formulation and small-batch compounding at 1mg resolution
• Analytical chemistry sample preparation requiring draftshield protection
• Jewelry and precious metals weighing using carat and troy ounce units
• Density determination on small specimens via the weigh-below hook
• Research laboratory weighing bridging precision and analytical performance
