Overview
The Sartorius Entris® II BCA Advanced Analytical Balance is an engineered solution for routine and regulated laboratory weighing tasks requiring high repeatability, traceable calibration, and operational robustness. Based on Sartorius’ proprietary monolithic sensor technology—developed and refined over nearly 150 years of German precision engineering—the Entris® II BCA delivers stable, drift-resistant measurements under variable environmental conditions. It operates on the principle of electromagnetic force compensation (EMFC), where the restoring force required to maintain zero displacement of the load receptor is precisely measured and converted into a mass reading. This architecture ensures long-term stability, minimal warm-up time (<5 minutes), and rapid settling times (typically <2 seconds at full capacity), making it suitable for high-throughput QC labs, academic teaching environments, and GLP-compliant quality control workflows.
Key Features
- Monolithic EMFC sensor with integrated temperature compensation for consistent readability across ambient fluctuations
- Real-time electronic leveling system with visual/audible alert and interactive on-screen guidance—eliminates manual bubble-level dependency and reduces setup error
- CalAuditTrail™: Automated, tamper-evident audit trail compliant with FDA 21 CFR Part 11 requirements; records date/time stamps, operator ID (if enabled), calibration weight values, and leveling status
- Graphical capacitive touchscreen interface with intuitive icon-based navigation and multi-language support (English, German, French, Spanish, Chinese, Japanese)
- 13 built-in weighing applications including parts counting, percentage weighing, density determination, formulation, checkweighing, and statistical analysis
- IP54-rated enclosure with chemically resistant housing (PBT polymer), stainless steel pan, and anti-static coated draft shield glass
- @start self-diagnostic function performs automatic internal verification at power-on, confirming sensor integrity, leveling status, and calibration validity before first use
- Three-tier data security protocol: configurable access levels (Operator, Supervisor, Administrator) restrict export, calibration, and configuration changes
Sample Compatibility & Compliance
The Entris® II BCA accommodates standard laboratory samples up to 12.2 kg, with optimal performance maintained for typical analytical masses ranging from 10 mg to 200 g when used with appropriate draft shields. Its rectangular weighing pan (180 × 180 mm) supports uniform load distribution and minimizes edge-loading errors. The balance complies with international metrological standards including OIML R76-1 (Class I), ISO/IEC 17025:2017 (for accredited calibration laboratories), and USP / for pharmaceutical weighing. Optional connectivity modules enable integration into LIMS or ELN systems with full electronic record integrity per ALCOA+ principles.
Software & Data Management
Data output is supported via RS232, USB Device (for printer/dongle), and optional Ethernet or Bluetooth interfaces. Sartorius LabX® Lite software (included) provides seamless data capture, report generation, and basic compliance reporting—including CalAuditTrail export in PDF or CSV format. All calibration and leveling events are digitally signed and timestamped; historical logs are retained for ≥10,000 entries. Audit trail files meet regulatory expectations for reviewability, retention, and non-repudiation—critical for FDA, EMA, and PMDA inspections.
Applications
- Pharmaceutical raw material and finished product assay in accordance with USP and EP monographs
- Formulation development and batch release testing in GMP environments
- Academic research requiring traceable mass measurement for stoichiometric reagent preparation
- Environmental testing labs performing gravimetric analysis of filter residues or particulate matter
- Food and beverage QA departments conducting moisture loss, ash content, or yield calculations
- Materials science labs performing density profiling of polymers and composites
FAQ
Does the Entris® II BCA support external calibration weights?
Yes—it accepts standard Class M1 or better calibration masses via its internal motorized calibration mechanism; manual calibration is also possible using external weights.
Is the touchscreen compatible with gloved operation?
The capacitive display responds reliably to standard nitrile or latex gloves; sensitivity settings can be adjusted in the service menu.
Can CalAuditTrail data be exported without administrator privileges?
No—export functionality requires Supervisor or Administrator credentials to preserve data integrity and prevent unauthorized modification.
What is the warranty coverage for the Entris® II BCA?
Sartorius provides a standard 3-year limited warranty covering parts and labor, extendable to 5 years with Sartorius Care service plans.
How often must the balance be leveled during daily use?
Once per day is sufficient under stable lab conditions; the real-time level sensor continuously monitors inclination and triggers alerts only if deviation exceeds ±0.5°.
