Sartorius Practum1102-1CN Precision Balance

Overview

The Sartorius Practum1102-1CN is a high-performance precision balance engineered for routine laboratory weighing tasks requiring consistent accuracy, robust mechanical stability, and regulatory-compliant data integrity. Designed according to electromagnetic force compensation (EMFC) principles, it delivers stable, drift-compensated measurements across dynamic environmental conditions — including minor vibrations, air currents, and thermal fluctuations common in shared lab spaces. With a maximum capacity of 1100 g and readability of 0.01 g (10 mg), the Practum1102-1CN meets the definition of a Class II precision balance per OIML R 76 and ASTM E898–22 standards. Its sealed, corrosion-resistant weighing cell and rigid aluminum die-cast housing ensure long-term metrological stability and resistance to mechanical stress during frequent use. The balance operates within an ambient temperature range of 10–40 °C and relative humidity up to 80 % RH (non-condensing), making it suitable for QC labs, educational institutions, and production support environments where reproducibility and traceability are essential.

Key Features

• Electromagnetic force compensation sensor with active drift correction and automatic internal temperature stabilization
• Integrated draft shield with quick-release side panels and adjustable rear airflow vents for optimal weighing stability
• Lower hook assembly for below-balance density determination and heavy or oversized sample weighing
• Large, backlit graphical display with intuitive icon-based navigation and multilingual interface (English, German, French, Spanish, Chinese)
• USB-B port compliant with virtual COM port protocol for direct data streaming to Microsoft Excel®, LabArchives®, or LIMS without proprietary drivers
• Programmable print intervals (1–999 s) supporting GLP-compliant timestamped output via RS-232 or USB-connected printers
• Supervisor lock function enabling password-protected restriction of menu access — ideal for teaching labs and standardized SOP execution
• Peak Hold mode with configurable hold duration (1–60 s) for capturing transient readings during unstable weighing scenarios (e.g., live animal weighing, viscous material settling)
• LevelControl™ system featuring oversized front-mounted leveling feet and integrated bubble level indicator for rapid, repeatable instrument leveling

Sample Compatibility & Compliance

The Practum1102-1CN accommodates diverse sample forms — solid masses, granular powders, low-viscosity liquids, and irregularly shaped objects — without compromising repeatability. Its 216 mm diameter stainless steel pan provides ample surface area for large containers or multi-step tare operations. For density determination, the optional Sartorius Density Kit (Order No. YDK01) enables rapid calculation of solid material density using Archimedes’ principle, with automatic buoyancy correction applied per ISO 1183-1. The balance supports multiple regulatory workflows: audit trail logging (via optional software), user-defined calibration due dates, and full compliance with FDA 21 CFR Part 11 requirements when paired with Sartorius LabX® software. All internal calibration records, weighing events, and configuration changes are time-stamped and user-identified, satisfying ISO/IEC 17025 clause 7.7 and EU GMP Annex 11 expectations for analytical instrument qualification.

Software & Data Management

Data export is natively supported through ASCII-formatted USB transmission, compatible with CSV parsing in spreadsheet applications. For advanced traceability, the balance integrates seamlessly with Sartorius LabX® standalone software, enabling automated report generation, electronic signature capture, deviation alerts, and full 21 CFR Part 11 compliance (including role-based permissions, audit trail review, and secure electronic records). Raw weighing data includes metadata such as date/time stamp, operator ID (if configured), balance ID, net/gross/tare values, stability status flag, and environmental condition tags (when connected to optional temperature/humidity sensors). All exported files adhere to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Quality control testing of raw materials and finished products in pharmaceutical, food, and chemical manufacturing
• Formulation and compounding in research laboratories requiring precise mass-based ratios
• Educational demonstrations of metrology fundamentals, uncertainty propagation, and statistical process control
• Density analysis of metals, polymers, and ceramics per ASTM D792 and ISO 1183
• Checkweighing of packaged goods against predefined tolerance limits (±% deviation mode)
• Parts counting of uniform components (e.g., tablets, fasteners, microelectronics) with automatic unit weight averaging
• Weighing under non-ideal conditions — including animal studies, field-deployed mobile labs, and vibration-prone industrial settings

FAQ

What calibration standard is required for external calibration of the Practum1102-1CN?
A certified Class M2 or better weight set (e.g., ASTM E617 Class 3) with nominal values covering at least 5%, 50%, and 100% of full scale (55 g, 550 g, and 1100 g) is recommended for routine verification and adjustment.
Does the balance support internal calibration?
No — the Practum1102-1CN is externally calibrated only; it does not include motorized internal calibration weights.
Can the USB interface be used for remote control via PC?
Yes — when used with Sartorius ComSoft® or third-party serial terminal emulators, the USB port supports command-driven operation (e.g., TARE, PRINT, GETWEIGHT) using standard SCPI-like syntax.
Is the balance suitable for use in a fume hood?
It may be installed in a fume hood only if airflow velocity at the pan position remains below 0.2 m/s and the hood is operated with sash fully closed during weighing; otherwise, measurement instability will occur.
How is regulatory compliance validated for audit purposes?
Instrument qualification documentation (IQ/OQ/PQ templates), calibration certificates, and software validation packages are available from Sartorius upon request and are aligned with ISO 13485, ICH Q7, and USP requirements.
